Angelo Bodetti Expert Confident picked Feb 22, 2026 (6 days before fight)
Ailín Pérez

Angelo is shocked that Ailín Pérez is only a -165 favorite, believing she should be a -300 favorite. He highlights Pérez's relentless takedowns and pressure, noting that Macy Chiasson gets taken down easily and has been on a losing skid. He expects Pérez to shoot takedowns and win a decision, especially with the Mexican judges favoring aggression.

Expresses surprise at the odds, says Ailín should be a -300 favorite.
"Ailen should be a minus 300 favorite. I am shocked to see that Macy Chasson is even a reasonable underdog."

Ailín Pérez

Big Brady picks Ailín Pérez but expresses hesitation due to elevation concerns and Pérez's history of gassing. He compares Macy Chiasson to 'female Phil Rowe,' noting she is big but ineffective and can be controlled on the ground. He believes Pérez can take Chiasson down and win the first two rounds, but the third could be sketchy. He predicts a decision win.

Diary of a Pro Gambler Expert Hesitant picked Feb 28, 2026 (fight day)
Macy Chiasson

The host is betting on Chiasson despite her inconsistency because the odds are too wide. He believes Chiasson is better than Pérez everywhere: she has a huge size and reach advantage, is a better striker and grappler, and has superior cardio. However, Chiasson has self-destructive tendencies and bad fight IQ, making her unreliable. The host caps the fight at 50/50 because Chiasson only shows up half the time, but at +149, the value is too good to pass up. He also notes Pérez's cardio may suffer at high altitude.

"There's no way Chersison should be an underdog in this fight. The odds just don't make any sense at all. ... Problem is quite often Chazon doesn't show up."
LU
Lucrative James Expert Confident picked Feb 22, 2026 (6 days before fight)
Ailín Pérez

James favors Pérez due to her wrestling and top control, which should neutralize Chiasson's striking. He notes Chiasson's confidence issues and tendency to wilt when pressured. James predicts Pérez wins by decision, though he admits bias as he knows Pérez personally.

"My pick will be E Island Perez to win this fight. Most likely via decision."

Macy Chiasson

The host picks Macy Chiasson as an underdog, surprised that Pérez is -185. He believes Chiasson is stronger and lands more damage, while Pérez relies on grinding top control. He expects Chiasson to defend takedowns and land the better strikes, winning a decision. He notes Chiasson's recent losing streak but thinks she matches up well.

"Give me Kason and Kason by decision."

Paul Shaughnessy Expert Confident picked Feb 25, 2026 (3 days before fight)
Ailín Pérez

Paul expects Pérez to use her wrestling to control Chiasson, who struggles with weight cuts and cardio at altitude. He sees a decision win for Pérez and recommends waiting for weigh-ins to confirm Chiasson's condition.

"AFP by boring stalling uh wrestling clinic and then somehow she'll be like borderline top 10 fighter at that point."

Ailín Pérez

The MMA Guru picks Ailín Pérez, trusting her takedown entries and physicality. He notes that Macy Chiasson looked bad in her last fight against Irene Aldana, and he believes Pérez can take her down and control the ground. He predicts a 29-28 decision win, acknowledging that Pérez has been improving and has a strong build for the division.

29-28 decision
"I'm going to go with Ailin Perez. ... I think she's going to win this fight by decision. A shitty decision, 29-28."
ZA
Zane Simon Expert Confident picked Feb 27, 2026 (1 day before fight)
Ailín Pérez

Zane picks Pérez because she is mentally consistent, has a clear winning game plan, and sticks to it. He notes that Chiasson is bigger and more powerful but breaks down mentally and physically. Pérez's takedown game and high motor should wear on Chiasson, who has a weak core and struggles with leverage.

Chiasson opened at -110, now +155; Pérez opened at -110, now -180. Zane calls these sensible odds.
"I'll take Perez too. I just think she seems very mentally consistent from one round to the next one minute to the next."

Ailin Perez vs. Karol Rosa
BETTING PREVIEW | SCOUTING REPORT | ODDS: Rosa (-265), Perez (+215)

Round 1
Since making her promotional debut in 2019, Rosa (18-6, 7-3 UFC) has gone to decision in all 10 of her UFC outings. The Brazilian may tie a record if she hears the final bell against Perez (11-2, 4-1 UFC)—but the only decisions for Perez have come when she won the fight. Serving as the only women’s match of the evening, the ladies try to do their division justice and improve on the paltry finish rate that marred last year. They will do so as referee Mike Beltran takes charge of the cage. A fist bump starts the action, and Rosa assumes the center of the cage to get going. Slowly walking towards the Argentinian, Rosa ignores incoming leg kicks so she can let her hands go. Perez charges her, clinching up with a body lock to try for a takedown, and Rosa slides away and breaks free. As she marches forward again, Rosa lets go with a right hand, and Perez times a tackling takedown to put the Brazilian on her back. Landing in half guard, Perez gets right to work with grinding top control. The action stalls out with Perez dragged back to the full guard, as she lands the occasional blow and amassing plenty of control time. Perez passes to half guard on the other side, and Rosa actively pushes off the leg and launches an upkick to make Perez turn away and back off. Rosa punches her way into another exchange, where she stuffs a takedown and flicks out a jab at the end of it. Perez connects with three punches and darts away before getting caught, and she reaches down in hopes of catching a leg kick to attempt a takedown. Rosa tosses her out of the way and hammers the midsection with a right hand, and both ladies reset. Perez times a spinning back fist as Rosa advances, and Rosa gives her back a low kick to think about. Perez attempts high kick, and she fails to check a low kick when planting. Rosa keeps chewing up the lead leg of her opponent, forcing a stance switch. Perez waves on Rosa to come at her, but the round ends before she can.

Round 2
Perez leads off the round with peppering low kicks, keeping Rosa at bay early. Rosa jabs her way forward, and she whips a low kick up that appears to slap into Perez’ groin. Beltran calls time, and Perez takes a few seconds before getting back to it. They resume trading leg kicks, and Rosa overswings a right hand that allows Perez to clinch her. Rosa gets out of the tie-up to push out a jab, and she defends a takedown shot with relative ease. Perez paws out a front kick, and she raises her leg in time to stop a low kick from harming her. Rosa keeps her hands up to block a one-two, and she parries a spinning back fist and a body kick while pressing forward. Perez jumps at her with a knee, and Rosa pushes it to the side and punches her in the face. Perez works the body with a kick, and she backs off when a one-two is fired down the pipe. Perez scores a spinning back fist, lands and releases a body kick before Rosa can get to her. Rosa settles down, loops a right hand over the guard, and is out of range before a counter gets to her. Rosa puts two punches on the jaw and pops Perez with a flying knee, but the subsequent takedown attempt slows her down. Rosa defends the first try, but the second effort by the Argentinian leads to her securing top position, landing in half guard. Perez prefers position over offense when getting the fight down, clinging to her foe and softening her up with the occasional blow. Perez hangs on in an arm-triangle setup, only to get bucked back to the guard when it starts getting close. The round ends with both women striking while horizontal, and it might go either way.

Round 3
There is a double touch of gloves to begin the last round, and Perez paws out her left hand to start things off. They connect at the same time with alternating single punches, and then back away to reset. Perez scores a low kick and gets popped with a left hook, but it is one-and-done for the Brazilian. Rosa aims an overhand right at the target, and it brushes past “Fiona,” who chambers and fires two kicks in rapid succession. Rosa stalks down her adversary and jackhammers her with an inside low kick that makes Perez stumble and change stances. Perez returns fire with her own calf kick, and Rosa no-sells it and hacks at the front wheel. Rosa ducks a telegraphed spinning back fist and checks a few low kicks while pressing ahead, and her landed leg kick consistently gets Perez’ attention. Two big punches from Rosa force Perez to tie her up, and she cannot hold her for long before Rosa breaks away. Rosa nails the front leg with a kick that makes Perez wince, and some swelling develops above Perez’ left eye. Rosa stays in her foe’s face, keeping just out of range of the flying strikes so she can sit down on left hooks and leg kicks. Perez is compromised but still in the fight, and at the 90-second mark, Rosa does not appear to be aggressive to the point of forcing a finish. Instead, Rosa remains composed, slowly chipping away at either leg and jabbing her way forward. Perez smacks Rosa upside the head with a right hand, and Rosa stalks her around the cage lobbing punches and heavy kicks. Perez pushes her back with front kicks and a stomping kick to the knee, but Rosa decides to take a page out of her playbook and spin to strike. There is no finish, and the bantamweights go the distance to likely set a record for Rosa starting her UFC run with 11 straight decisions.

Ailín Pérez

Angelo picks Ailín Pérez as an underdog, believing her wrestling and forward pressure will be too much for Karol Rosa, who hasn't faced a strong wrestler recently. He notes that Rosa's takedown defense is untested against a wrestler of Pérez's style. He has a small bet on Pérez at +150 and is surprised the odds are widening instead of tightening.

Small bet half a unit on Ailín Pérez at +150; may double down or bet +3.5 rounds for cushion.

Ailín Pérez

Cody picks Ailín Pérez as an underdog, citing her wrestling and top control. He notes that Pérez has taken down all her UFC opponents and has improved rapidly at Fortis MMA. Rosa has poor takedown defense and no get-up game once taken down, as seen against Sarah McMahon and Norma Dumont. Cody believes Pérez will take Rosa down, control her, and win rounds. He also mentions that Rosa has no power and all her wins are by decision, so Pérez only needs to win the first two rounds.

Lucrative James Expert Confident picked Jan 15, 2025 (3 days before fight)
Karol Rosa

Lucrative James picks Karol Rosa, stating she is the better overall MMA fighter with superior striking, cardio, experience, and grappling. He acknowledges Ailín Pérez's tenacious wrestling and potential to cause problems early, but notes Pérez's poor cardio and striking, which often leads to her fading in round three. James observes that Rosa typically has her best round in the third, while Pérez fades, making a late stoppage or decision win for Rosa likely. He understands the appeal of Pérez as a big underdog due to her grappling, but ultimately favors Rosa's well-rounded game.

"I have to pick Carol Roser in this fight but I understand if you're taking Perez as a massive Underdog just because of the potential that this is women's MMA kind of close fight"

Karol Rosa

The MMA Guru picks Karol Rosa over Ailín Pérez. He argues that Rosa is better at MMA overall, with great takedown defense, ability to get back to her feet, and striking that doesn't look amateurish. He notes Rosa has competed with top division fighters like Irene Aldana and Norma Dumont, and outlanded Aldana. He sees this as a step up for Pérez against a real MMA fighter.

"I'm going to side with Carol Rosa I just think it's the next step in aen Perez's career where she actually faces a female MMA fighter who is good at MMA"

Ailin Perez (136.5: Missed Weight) vs. Darya Zheleznyakova

Round 1
In a fight that some have posited should not be happening today, Perez (10-2, 3-1 UFC) appears to be in much better shape than she was on Friday. The Argentinian still did miss weight as she cut down to 136.5 pounds, and her tremors and wobbly nature appear to be a thing of the past. Her team says the shakes were a ruse, but is Perez that good of an actor? Happy to take 20% of her foe’s purse, Zheleznyakova (9-1, 1-0 UFC) would also like to cash a second check and further work her way up the women’s bantamweight ladder. There is no glove touch offered as this has developed into a chippy fight, and referee Herb Dean watches on. After a fair amount of circling, Perez eventually engages with a takedown shot. Zheleznyakova pushes her away, and they resume their staring contest. Zheleznyakova decides she would like to try the grappling game, and she gets Perez down and lowers herself to side control. Zheleznyakova bails on the position for some reason and stands, and she has to quickly defend a shot from the Argentinian. Zheleznyakova reaches her opponent with a right hand, and she stuff another try and connects with another right hook. Perez crashes the pocket and tackles Zheleznyakova to the mat with a body lock takedown, where she scrambles her way all the way to full mount. Perez opens up with a few punches as she gets dragged back to half guard, and she starts setting up an arm-triangle choke. Perez lowers her body weight down to pressure the Russian’s throat, and Zheleznyakova’s face transforms to a brilliant shade of red in a hurry. Before she even moves to side control or mount, Perez manages to elicit the tap she was seeking. Dean officially calls a halt to the match, and when Zheleznyakova stands, Perez twerks in her face. The fans don’t know what to think, but she does not care, as her celebration dance continues.

Daria Zhelezniakova

Cody picks Zhelezniakova as an underdog, citing the hometown advantage and Pérez's tendency to do just enough to win without finishing. He notes that Pérez's takedowns often lead to little damage, and the judges may favor the local fighter in close rounds. Zhelezniakova is a striker who can outland Pérez on the feet.

He notes Zhelezniakova has poor takedown defense and has been controlled on the ground. He expects Pérez to win by decision or ground-and-pound, but is not interested in the price.

Paul initially picks Pérez due to her takedown threat, but after discussion, he switches to Zhelezniakova citing the CF model and hometown cooking. He notes that Pérez doesn't do enough with takedowns and that the fight could be close, favoring the local fighter.

"I'm switching my pick CF do model... cornal is the pick"

The MMA Guru Expert Confident picked Sep 24, 2024 (4 days before fight)
Ailín Pérez

The MMA Guru picks Ailín Pérez over Daria Zhelezniakova, citing Pérez's size and strength, particularly her lower body power. He notes that Zhelezniakova has good striking but struggles with grappling, and Pérez has strong takedown entries. He expects Pérez to win via grappling.

"I'm going to go with aen Perez being big strong having good entries on takedowns and uh doing work from there"

Zane Simon Expert Confident picked Sep 27, 2024 (1 day before fight)
Daria Zhelezniakova

Zane thinks Zhelezniakova is a bigger athlete with a functional game she sticks to, while Pérez is too small and relies on a grappling style that may not work against better fighters. He notes that Pérez has been winning due to commitment to a simple game, but Zhelezniakova will have opportunities to tag her and force ugly shots.

"Zhelezhnikov seems like it's just way bigger, has a functional game she sticks to. That's enough."

Joselyne Edwards vs. Ailin Perez
BETTING PREVIEW | SCOUTING REPORT | ODDS: Perez (-198), Edwards (+164)

Round 1
One lone women’s bout will play out on the billing tonight, and it comes now at the 135-pound division between two women that will not likely go out for a beer after. In the last few years, Argentina’s Perez (9-2, 2-1 UFC) has built a pattern of winning two and losing the third, and she currently rides a two-fight win streak. Looking to keep that pattern going will be Edwards (13-5, 4-3 UFC), who has heard the final bell in all seven of her previous outings in the Octagon. Referee Gasper Oliver may be in it for the long haul, and he clocks the grudge match in as they have no interest in touching gloves first—although Perez does offer. Perez backs off and reaches out low kicks, and Edwards checks one and throws a front kick back. Perez punches, and she moves in to grab hold of Edwards and drags her back to the cage by putting her own back to the wall. This is all part of the plan, even as she eats a solid knee to the body, as she slings Edwards down to the floor. “La Pantera” fights her way back up with the fence behind her, so Perez mat returns her back down with a throw that plants her on her back in the middle of the cage. Perez lands a few punches from on top, and she is warned for punches to the back of the head. Edwards sweeps her when Perez tries to pass guard, and a wild scramble results in multiple reversals and changes in position. Edwards finds her way on top, and Perez flips her back over, only to get put on her back as Edwards times Perez advancing again. Edwards scoots her way to the cage wall, and as soon as she stands back up, Perez tosses her back down. “Fiona” settles down and hacks down with elbows, remaining more composed and less reckless so she can rack up control time without getting swept. Edwards hangs on with an arm-triangle off her back, and Perez completely ignores it as she resides in half guard, grinding out the round and dropping occasional elbows. Perez tries to move to mount, and Edwards remarkably flips her over once more. The amusing round ends with Edwards on top.

Round 2
Edwards comes out of her corner and takes the center of the cage, only to get driven back by two punches and an attempted high kick. Edwards replies with a single body kick, and she blocks a head kick aimed her direction. Perez defends from a high kick and a haymaker by swiping out with a left hook that stuns Perez momentarily. Perez shoots recklessly for a takedown, and Edwards snatches up a guillotine that is tight in a hurry. The Panamanian uses the submission to push Perez on her back, and she lands in half guard. Edwards postures up to land strikes occasionally, and as she lowers herself down, she smashes Perez in the face with her forehead with what appears to be an intentional headbutt. Perez clutches her cheek after the illegal blow, and Oliver calls time. Perez appears compromised from the blow, and Oliver simply asks Edwards to watch her head without issuing a hard warning or taking a point. Oliver clocks them back in, and Perez is still holding onto her cheek. When they do continue, Perez totally shocks her foe with a spinning back fist, knocking Edwards clean off her feet. Edwards appears stunned, and she somehow comes to her senses as Perez does not give chase. Instead, the two appear confused, and Perez decides to tackle Edwards to the mat. Perez falls off the side, and she pursues an armbar, only for Edwards to flip her over. Edwards holds top position to the bell.

Round 3
Once more, Edwards is the aggressor to lead off the round, but Perez takes advantage of that by kicking her hard in the ribs. Edwards overswings, and Perez attempts to take her down. Edwards stonewalls her, and Perez tries again to no avail. On this second effort, Edwards shuts her down and pushes her towards the fence. Perez kicks off the fence to change her position, and she hunts for a hip toss but cannot get it this time. Edwards stays tightly pressed in the clinch, and the two tie their legs up until Perez chucks her to the mat. Edwards stands back up, and Perez backs off and pulls on the fence to stand back up. Edwards backs her off with a front kick, and she chases after a retreating Perez and kicks her in the front leg as well. A second low kick from Edwards forces a brief change in stances, and the pace wanes significantly. Perez comes up short on a big left hand, and Edwards spins with a back fist but is blocked. Perez tosses out a half-hearted high kick that easily gets redirected, and her leg kick comes up short. Edwards goes after her with reaching punches, and she misses the mark. Edwards plants a kick on the chest, and they trade leg kicks until Edwards catches her with a few punches. Perez spins with a back fist, and they both smile and touch gloves in a potential sign that the bad blood is dissipating. They keep slamming one another in the front leg with kicks, and Perez turns her hips to her side to deliver a solid side kick to the body. Edwards throws a few punches, and Perez rushes forward to take her down and lands it with seconds to spare. As Edwards stands, the fight ends, and the two women hug it out and appear to apologize to one another for everything that transpired between them. The teams also shake hands with one another, and the bantamweight share a finalizing embrace.

Angelo Bodetti Expert Confident picked May 26, 2024 (6 days before fight)
Ailín Pérez

Angelo picks Ailín Pérez to win due to her relentless wrestling and forward pressure, despite her sometimes sloppy control on the ground. He thinks Joselyne Edwards is underrated and has good kickboxing and improved takedown defense, but believes Pérez's wrestling will be the difference. He plans to bet on Edwards plus 3.5 and over 2.5 rounds as prop bets.

Ailín Pérez

Big Brady thinks Ailín Pérez will be under the radar. He expects her to wrestle, get multiple takedowns, control time, and ground strikes. He notes Joselyne Edwards struggles with getting taken down and held down. He does not see a finish but expects a solid score at low ownership.

Cody Saftic Expert Hesitant picked May 29, 2024 (3 days before fight)
Ailín Pérez

Cody picks Pérez but is hesitant, noting she slowed down in the third round against Lucie Pudilova and took damage. He expects Pérez to get early takedowns and control the fight, but worries about her cardio. He thinks she will win by decision but is not confident enough to add her high on parlays. He acknowledges Edwards' fights are close and could go either way.

"I expect her to get takedowns early, control and probably win this fight by decision... but round three was like she started to slow down... that would be my only concern."

Daniel Vreeland Expert Hesitant picked May 28, 2024 (4 days before fight)
Ailín Pérez

Daniel notes Edwards has improved but still gets reversed. He thinks Pérez's relentless takedown attempts will be enough if Edwards makes a mistake. He reluctantly picks Pérez but says it's dog or pass.

"I'm gonna reluctantly say aen is able to capitalize on Joselyn throwing kicks and falling"
MM
MMA Lock of the Night Expert Confident picked May 27, 2024 (5 days before fight)
Ailín Pérez

The host expects Pérez to exploit Edwards' poor takedown defense and grind out a decision. Pérez's strength and top control should neutralize Edwards' volume striking, and Edwards' lack of finishing threat late in fights allows Pérez to survive her own cardio issues. The grudge match may add emotion, but Pérez's discipline and physicality should prevail.

"I think we'll see her exploit the takedown defense issue in Joselyn Edwards's game and that will allow Perez to just grind her out from that top position."
PA
Paul Shaughnessy Expert Confident picked May 29, 2024 (3 days before fight)
Ailín Pérez

Paul picks Pérez, citing her physical strength and top pressure. He notes Edwards' fights are always close and go to decision, and she lacks volume and power. Paul believes Pérez will initiate takedowns, control the clinch, and win a decision. He mentions Pérez's win over Stephanie Egger and her grappling credentials. He expects the New Jersey crowd to favor Pérez's aggressive style.

"Perez seems to just kill that space chest to chest... she's physically strong... she's going to be pressing Edwards into the cage... Perez by decision."

The MMA Guru Expert Confident picked May 27, 2024 (5 days before fight)
Ailín Pérez

The MMA Guru picks Ailín Pérez based on MMA math: Pérez dominated Lucy Pudilova on the ground, while Edwards was outgrappled by the same opponent. He acknowledges that both fighters are similar but believes Pérez's grappling is superior. He notes that Edwards is a bit bigger and rangier but hasn't beaten a good UFC fighter.

"I'm going to go with aen Perez here purely based on the fact that aen Perez dominantly defeated a opponent that they share in common"

Ailín Pérez

Big Brady finds Perez's nickname change to 'Nurmagomedov' hilarious but thinks she earned it with 10 takedowns in her last fight. He sees Perez as a bully who will come forward, push Pudilová against the cage, and take her down repeatedly. He notes Pudilová has better striking but has struggled with takedowns and control in the past. He believes the odds flip is correct and Perez should be the favorite, winning a grinding decision.

Lucie Pudilová

Pudilová has improved her grappling significantly since her first UFC stint, now using it offensively. She is the cleaner striker and can cut up Pérez on the feet. Even on the ground, Pudilová can throw up submissions and reverse positions. Pérez relies on strength and bullying, which may not work against a technically better grappler like Pudilová. Pudilová wins by decision.

"I'm actually going to lean with pudova to win this fight I think she batters uh Perez throughout this matchup I think she nullifies the control of Perez with her own damage and that will end up being the Difference …"

The MMA Guru Expert Confident picked Nov 14, 2023 (4 days before fight)
Lucie Pudilová

The MMA Guru picks Lucie Pudilová over Ailín Pérez, noting Pudilová's height and reach advantage as a rangier striker. He rates Pudilová's wins higher, including a close fight with Joselyne Edwards and a win over Yanan Wu, while criticizing Pérez's decision win over Ashley Evans-Smith as unimpressive. He believes Pudilová's improvement and range will be key if the fight stays standing, and doesn't see Pérez out-grappling her.

"I'm going to go with Lucy Pudilova... I think she'll have improved more, I think she's rangier taller, I reckon that's going to be a factor here if it ends up staying on the feet."

Ailín Pérez

Angelo picks Ailín Pérez, believing Ashlee will be rusty after a two-year layoff due to a USADA suspension. He notes Pérez defended five takedowns in her debut and got one of her own, while Ashlee is well-rounded but not a killer. He acknowledges Ashlee's experience makes her a live dog but thinks Pérez's youth and activity give her the edge.

Ailín Pérez

Big Brady picks Ailín Pérez because Ashlee Evans-Smith is coming off a 2.5-year layoff, is 36 years old, and was 1-4 in her last five fights before the suspension. He doubts she will show a much improved version of herself. While he acknowledges Pérez is not great, he believes her youth and activity will be enough to win. He calls laying -225 'very irresponsible' and says he won't bet it, but he thinks Pérez wins the fight.

He believes Pérez will follow a similar game plan to Norma Dumont, using forward pressure and power to nullify Evans-Smith's wrestling and win by decision. Despite Pérez being raw, the host favors her due to Evans-Smith's inactivity and age.

He notes that while Ailín Pérez is a good prospect who can bully opponents, Egger is likely to get the takedowns and work control. He thinks the odds are too wide and would consider betting on Pérez with a plus 3.5 round buy or a win inside distance decision no action prop.

Stephanie Egger

Big Brady picks Stephanie Egger to win by first-round submission. He notes that Ailín Pérez has looked good but against very low-level competition, and this is a huge step up. He believes Egger's experience against better fighters and her ability to get the fight to the mat will be decisive, and that Pérez has faced no adversity and will struggle when she does.

Stephanie Egger

Cody picks Stephanie Egger, noting that she is a judo black belt with strong clinch and ground game. He argues that Ailín Pérez is a low-level fighter with a padded record and poor competition. Egger should be able to take Pérez down and submit her, as she has done to similar opponents. Cody likes the under 35.5 significant strikes for Egger on PrizePicks, as her fights are usually grappling-heavy and low-volume.

Daniel Levi picks Ailín Pérez as an underdog, believing her physicality and aggression could overwhelm Stephanie Egger. He notes that Pérez likes to tie up and impose her will, which could neutralize Egger's judo. He acknowledges it's a 50/50 fight and that Pérez might get thrown, but he leans toward the upset.

Stephanie Egger

The host leans towards Stephanie Egger, believing she is the better overall grappler and will be more proactive on the mat, possibly finding a submission or dominating from top position. However, he is hesitant to bet at -300, fearing that Pérez might transfer her regional success to the UFC. He predicts Egger inside the distance but will likely stay off the fight entirely.

Macy Chiasson

The host is betting on Chiasson despite her inconsistency because the odds are too wide. He believes Chiasson is better than Pérez everywhere: she has a huge size and reach advantage, is a better striker and grappler, and has superior cardio. However, Chiasson has self-destructive tendencies and bad fight IQ, making her unreliable. The host caps the fight at 50/50 because Chiasson only shows up half the time, but at +149, the value is too good to pass up. He also notes Pérez's cardio may suffer at high altitude.

"There's no way Chersison should be an underdog in this fight. The odds just don't make any sense at all. ... Problem is quite often Chazon doesn't show up."

Ailín Pérez

Zane picks Pérez because she is mentally consistent, has a clear winning game plan, and sticks to it. He notes that Chiasson is bigger and more powerful but breaks down mentally and physically. Pérez's takedown game and high motor should wear on Chiasson, who has a weak core and struggles with leverage.

Chiasson opened at -110, now +155; Pérez opened at -110, now -180. Zane calls these sensible odds.
"I'll take Perez too. I just think she seems very mentally consistent from one round to the next one minute to the next."

Ketlen Vieira vs. Macy Chiasson
BETTING PREVIEW | SCOUTING REPORT | ODDS: Chiasson (-118), Vieira (-102)

Round 1
What was once a likely bantamweight title eliminator has become a featherweight fight of little import, thanks to Vieira (14-4, 8-4 UFC) being unable to get down to the 136-pound limit. Chiasson (10-3, 8-3 UFC), with eyes to the future, gladly accepts 25% of Vieira’s purse before getting to punch her in the face for her transgression. Referee Mark Smith stands by to keep things on the up-and-up, although the match still opens with the ladies clapping hands first. Vieira takes to the center of the Octagon, with Chiasson circling around her probing her with low kicks and jabs. The Louisiana native manages her distance well, staying active and not letting Vieira strike her. Chiasson fires up a head kick, and uses it as a way to open a left hand up. Vieira looks to counter, but Chiasson is out of range from everything besides a pair of body shots. Vieira sits down on a right hand, shaking Chiasson up a little and forcing her to reset. Chiasson goes for a spinning wheel kick that misses the mark significantly, and Vieira tracks her down and smashes her in the face with a ferocious right hand. Chiasson wears it well but is not a fan, scooting out of the way before Vieira can pin her down again. Chiasson prods the body with jabs and kicks, and Vieira counters with a right hand over the top. Vieira connects with a few fast hands, and when Chiasson clinches, she lays into her with another flurry of blows. Both women try to land elbows from up close, but they sway just enough to let them soar past one another. Vieira bullies Chiasson against the fencing, and Chiasson slowly but methodically fights her way out while using a knee to get some space. Vieira pushes her close again and back to the wall, and she punches her way out rather than glom on to the taller woman. Chiasson chips at the front leg a few times, and she catches Vieira on the temple with a long right hand. Vieira scores a combo of punches to end the round.

Round 2
The moment gloves are touched, Chiasson shoots in for a takedown. Vieira’s defense spikes them both on their faces, and she recovers just the faster to turn to the side to establish top position. The Brazilian hops a few times to get herself in the conventional guard, but she is intent on passing to somewhere better and clinging to an arm-triangle choke setup. Chiasson is wise to it and she fights back with elbows and even flirts with an armbar setup, but she is stifled when Vieira stays flatly pressed to her. Chiasson pushes off the hips, and she turns to a knee but inadvertently gives up her back. As she rolls, Chiasson finds herself still in Vieira’s clutches. Vieira gets herself back on top in the guard, smothering the American while not otherwise utilizing much offense. Vieira lands punches every so often, preferring to rack up control time while shutting down anything Chiasson can do. Chiasson slashes off her back with her elbow, and she scores two more when Vieira postures up. Vieira rides out the remainder of the round on top.

Round 3
Before the third round begins, Smith calls in a cutman to slice the tape off of Vieira’s glove. The two touch gloves, and Chiasson comes out shot out of a cannon. Punching her way into a single, Chiasson finds that the Brazilian is not about to go down and falls to her back. Vieira establishes herself on top again, and she embraces the grind immediately. It does not take Smith long to ask for more activity, with Vieira content to work the body with short strikes and remain busy enough to keep her position. Vieira sits up and drills Chiasson with a pair of punches that lead her corner to hoot and holler, and Chiasson fails to employ butterfly hooks to get some space. Vieira’s smothering ground control is sucking the energy out of the building, and when Chiasson attempts to escape, the Brazilian is there to shut her down completely. Smith again asks for Vieira to do more, and it is Chiasson who does some damage with a vicious elbow that rips open a cut on Vieira’s forehead. Chiasson uses the moment to explode to her feet, where she starts laying into Vieira with punches and elbows. Vieira tries to clinch, and Chiasson bails on it and leaps at her with lunging punches and kicks. Chiasson drills the Brazilian with exhausted one-twos, and her late onslaught may sway a judge or two because of the damage inflicted. The not-so-thrilling fight comes to an end.

Angelo picks Ketlen Vieira, believing she can bully Macy Chiasson by closing the distance and negating Chiasson's length. He notes that Vieira lost to Kayla Harrison (potential champion) while Chiasson's win was due to a cut. He is cautious about betting on someone coming off a loss but would bet on Vieira as a dog if odds flip.

He notes that Chiasson has improved but still struggles in the clinch and is easy to hit. However, he acknowledges that if Vieira cannot get takedowns, she will struggle due to her poor striking confidence.

Mayra Bueno Silva vs. Macy Chiasson
BETTING PREVIEW | SCOUTING REPORT | ODDS: Bueno Silva (-115), Chiasson (-105)

Round 1
With the 135-pound title picture in flux, the winner of Silva (10-3-1, 1 NC; 5-3-1, 1 NC UFC) and Chiasson (9-3, 7-3 UFC) could be next in line for a shot at gold—although Silva fell short her last time out vying for the title in an exceptionally dull affair. The 32-year-old bantamweights come together to touch gloves to start the fight all while referee Chris Tognoni prepares himself to officiate. Silva maintains the center of the cage while Chiasson strafes on the outside. Chiasson swings too hard with a right hand, resulting in Silva grabbing hold of her and clinching her to land a knee and an elbow. Chiasson separates and reaches out with a left hook, and on a second effort she misses with the same strike as a body kick belts her in the ribs. Silva kicks the front leg, sticks out a right hand and evades a counter. Silva plants the ball of her foot on Chiasson’s chest, fires a head kick off from the other leg and punches her way into the clinch. When up close and personal, the Brazilian strikes with an elbow, and Chiasson answers her with one of her own. Silva breaks out of the tie-up after absorbing this strike, and she misses a body kick and keeps turning to slap Chiasson in the face with a wheel kick. Chiasson scores a front kick and a low kick, and she keeps her guard up to defend a head kick. Silva works the body with several punches and knees, and she pulls Chiasson down to knee her in the face a few times. Chiasson defends from a takedown and walks to the fence, and she uses body shots in close range with several uppercuts. Silva tries to go after the trip, and Chiasson stifles it and takes a few knees to the midsection. Silva gets off an elbow, and Chiasson rips the body and goes up high in a flurry. Silva backs herself up against the cage wall, and the two end up back in the clinch trading body blows. Chiasson lines up several knees to the body, and Silva pushes away and tags Chiasson with a right hand. Silva uses the opportunity to shoot for a double, and Chiasson sprawls against the wall but is tripped to a knee for a second. Chiasson springboards back up and presses Silva against the wire until the round ends.

Round 2
The ladies clap hands, and Chiasson is ready to party and starts trading strikes. Head shots lead to other punches to the body and kicks, and she decides to take the fight down to the ground and succeeds. One single elbow from Chiasson slices a massive cut open above Silva’s right eyebrow. Chiasson stays tightly pressed to her opponent, and Silva throws her legs up in pursuit of an armbar. Chiasson remains stacked up on top until Silva abandons it, and Silva kicks her off of her. Chiasson stands and whips low kicks at the thigh from both sides, while Silva lays on her back with her hands behind her head bicycling upkicks. Chiasson decides to let Silva up, and Tognoni calls time to bring in the physician to observe the monstrous cut above her eyebrow. This appears to be a fight-ending cut, nearly two inches wide from one to the other. The doctor tells Tognoni the cut is extremely deep and that the blood will pour into her eye, and it already has as Silva’s face is covered with blood. Tognoni waves the fight off, and Silva is incensed, to the point that she climbs out of the cage and tries to plead her case to UFC head Dana White. He and others around him back away as she is leaking all over the place, and White tells her she needs to go see the doctor and get patched up. No matter her cries, this is a legitimate stoppage and way to win the fight—the head wound is no joke, much like the headliner of PFL last night.

The Official Result
Macy Chiasson def. Mayra Bueno Silva R2 1:58 via TKO (Doctor Stoppage)
CO
Cody Saftic Expert Confident picked Jun 26, 2024 (3 days before fight)
Macy Chiasson

Cody picks Chiasson, citing her size, wrestling, and cardio advantages. He notes that Bueno Silva has poor takedown defense and cardio issues, and that Chiasson has consistently scored takedowns against tough opponents. Cody believes Chiasson will use her clinch work and wrestling to wear on Bueno Silva, and that she can win a decision or possibly get a submission. He also mentions that Bueno Silva's best wins are over lower-tier competition and that she failed a drug test.

"I'll take Macy Chiasson to again probably a close competitive first round... she may get taken down herself but it's all about using that strength and physicality."
DA
Daniel Vreeland Expert Confident picked Jun 27, 2024 (2 days before fight)
Macy Chiasson

Daniel Vreeland picks Macy Chiasson because she has looked better recently, rounding out her game and improving her takedown defense. He notes that Chiasson is a better striker than Bueno Silva and has a significant reach advantage (six inches). Vreeland believes Bueno Silva's only path to victory is grinding, but Chiasson has the skills to stuff takedowns and keep the fight standing. He also cites Bueno Silva's poor gas tank in her last fight against Raquel Pennington as a concern.

"I'm going to go with Macy Shon... she's looked a lot better as of late... she seems to be really working on her takedown defense... she's always been a better Striker than my rib bua silda."
DA
Daniel Vreeland Expert Confident picked Jun 27, 2024 (2 days before fight)
Mayra Bueno Silva

Daniel believes Bueno Silva has championship potential, citing her power, calf kicks, and opportunistic submissions. He notes that her loss to Pennington came when she was sick and had a busted eardrum. He views Chiasson as having physical attributes but being flaky and prone to mistakes under pressure. He thinks Bueno Silva is meaner, more athletic, and has a higher trajectory.

"I'm going Mya... I think she's meaner I think she's more athletic and I think she's got a higher trajectory I think she can be a champion."
JE
Jeff Fox Expert Confident picked Jun 27, 2024 (2 days before fight)
Macy Chiasson

Jeff Fox picks Macy Chiasson, echoing Vreeland's reasoning. He notes that Bueno Silva did not look good in her last fight and has gas tank concerns. Fox points out that Chiasson is way bigger, a better striker, and has improved her grappling. He also mentions that Chiasson's coach will keep her focused.

"I like the Macy chaon as well... buo Silva did not look good in her last fight... way bigger better Striker and as you said she's bringing better at her grappling."

MMA Lock of the Night Expert Lean picked Jun 25, 2024 (4 days before fight)
Macy Chiasson

The host leans Chiasson, citing her strength and ability to grind on Bueno Silva. He notes Bueno Silva is dangerous with submissions off her back early, but if Chiasson can control her against the cage for the first 6-7 minutes and then take her down, she will have success. He mentions the line has moved from +180 to nearly pick'em, indicating confidence in Chiasson.

Paul Shaughnessy Expert Lean picked Jun 26, 2024 (3 days before fight)
Mayra Bueno Silva

Paul picks Bueno Silva by submission, noting that her submission grappling is her biggest weapon. He acknowledges that Chiasson is bigger and has better wrestling, but believes Bueno Silva can catch her in a submission if the fight goes to the ground. Paul points out that Bueno Silva has a history of pulling off submissions from seemingly losing positions, and that the plus-370 odds for her by submission offer value.

"I found a couple of my books they got plus 370 on Bueno Silva by sub... I feel like that is the play."

He believes Chiasson can muscle her around and out-hustle her. He also mentions Chiasson's flexibility in submissions and her competitive fight against Norma Dumont.

"I'm going to go with Macy chasson... she's a lot than Mayra buo Silva"

Angelo Bodetti Expert Confident picked Mar 11, 2024 (5 days before fight)
Macy Chiasson

Angelo acknowledges Kianzad has a big striking advantage with her boxing, but she was unable to get up off the bottom in her last fight against Ketlen Vieira. Chiasson has added grappling to her game, taking down Norma Dumont six times and Irene Aldana three times. He thinks Chiasson will get takedowns and hold Kianzad down. He also suggests a plus 3.5 round bet on Kianzad as she might win a round on the feet.

Pannie Kianzad +3.5 rounds (buying points) if odds drop

Macy Chiasson

Big Brady picks Macy Chiasson to win by decision. He expects Chiasson's size and physicality to be too much for Kianzad, allowing her to control the fight against the cage and on the mat. He references Kianzad's recent loss to Vieira as a blueprint.

CO
Cody Saftic Expert Lean picked Mar 13, 2024 (3 days before fight)
Macy Chiasson

Cody leans toward Macy Chiasson, citing her size, physicality, and grappling advantage. He notes she has choked Kianzad out before and is the better grappler. However, he is wary of the minus 240 line due to Chiasson's weight cut struggles and long layoff. He suggests waiting for weigh-ins before betting.

"Macy Chiasson... she's a bigger stronger more physical bruiser on the feet... she's already choked her out once."
LU
Lucrative James Expert Confident picked Mar 12, 2024 (4 days before fight)
Macy Chiasson

Lucrative James picks Macy Chiasson to win, likely by submission or ground-and-pound TKO. He notes that Chiasson is physically stronger, has better grappling, and finished Kianzad before on The Ultimate Fighter. He also questions whether Kianzad has lost a step and mentions Chiasson's recent performances against tough opponents. He expresses concern about Chiasson's weight cut but still expects her to win.

MM
MMA Lock of the Night Expert Confident picked Mar 15, 2024 (1 day before fight)
Macy Chiasson

The host acknowledges Kianzad's striking advantage but believes she will be frustrated by Chiasson's grapple-heavy approach. He notes Chiasson's ability to bully opponents in the clinch and get fights to the ground easily, where she can rough up Kianzad from top position for the majority of the fight and win by decision.

"I think we'll see kiasan Drager to the mat rougher up from that top position and keep her there for the majority of 15 minutes eventually getting her hand raised by decision"
PA
Paul Shaughnessy Expert picked Mar 13, 2024 (3 days before fight)

Paul passes on betting this fight, noting Chiasson's weight cut issues and unimpressive recent performances. He mentions the bizarre liver kick loss to Aldana and questions her durability. He does not pick a winner and says it's a pass from a betting perspective.

"There's no way I bet minus 240 on Macy Chiasson it's going to be a pass from a betting perspective."

Macy Chiasson

Angelo picks Macy Chiasson, noting she can beat Irene Aldana the same way Holly Holm did: manage distance and use takedowns. He thinks Chiasson's length and grappling will be key, and she just took down Norma Dumont six times. He placed a small moneyline bet at +178, which has since moved to +160.

Irene Aldana

Big Brady picks Irene Aldana to win by decision, highlighting her 84% takedown defense and superior striking. He notes Macy Chiasson's path to victory relies on using her size and clinch, but Aldana's takedown defense is phenomenal and she has fought much better competition. He believes Aldana has more power and better cardio, and a finish wouldn't shock him.

"Give me Aldana to win by decision."
CO
Cody Saftic Expert Confident picked Sep 7, 2022 (3 days before fight)
Irene Aldana

Cody is confident in Irene Aldana, having already bet her at -161. He believes Aldana dominates on the feet, as Chiasson's wrestling is not highly rated and her cardio fades. He notes that Chiasson's move back to 135 could be problematic. He thinks Aldana's boxing and footwork will be too much.

Irene Aldana

Daniel Levi picks Irene Aldana but with low confidence. He notes Aldana's high output and power, but also her tendency to underperform in favored spots. He acknowledges Chiasson's physical advantages (height, reach) and improved wrestling, as seen against Dumont. Levi says he's been burnt by Aldana before and won't lay the chalk, but still sees her as the pick.

"While i definitely lean aldana it's just how many times am i gonna be burnt by this aldana chalk price so i ain't laying it personally the pick is aldana."

"I love Aldona in this matchup I think that she's gonna find that shot versus Macy harder cause you watch that Macy fight versus Norma Dumont was grappling grappling grappling dominating the first dominating the second the second Norma Dumont …"

Macy Chiasson vs. Norma Dumont (146.5: Missed Weight)
BETTING PREVIEW | SCOUTING REPORT | ODDS: Dumont (-220), Chiasson (+180)

Round 1
In this unexpected 147-pound catchweight affair, this time, it is not Chiasson (7-2, 5-2 UFC) who tipped the scales above the featherweight limit. Instead, it is Dumont (7-1, 3-1 UFC), who continues her issue with weigh-ins as she could not find the bantamweight cap well either. Depending on the result, and due to the thinness of the division, the victor here could be up next for a crack at Amanda Nunes’ 145-pound throne. Referee Keith Peterson is on call for this nonsense-free title eliminator, and the fighters are intense and but still touch gloves to start things off. Chiasson keeps a wide berth and prods out with a front kick to the knee, and she switches things up with a high kick that gets blocked. Chiasson targets another high head kick, and wades forward with a pair of punches. They trade leg kicks, and Chiasson stays a little more active from distance as Dumont watches on. When Chiasson leaves a kick out too long, she gets knocked back from an overhand right. Chiasson fakes a level change, and Dumont is ready to meet her and delivers a right hand over the top. A front kick from Chiasson slaps into Dumont’s face, and Dumont tries and fails to toss out a leg kick. The pace is slow but deliberate, as Chiasson comes out with a body kick and a straight left hand. “The Immortal” charges and whiffs on a handful of punches, and she loads up with a right hand that makes Chiasson turn. Chiasson goes after another low kick, and Dumont smacks her again with a right hook. Dumont grabs hold of a clinch, and Chiasson breaks free and plants her left fist on Dumont’s jaw. Dumont shakes her head, but she absorbed the blow cleanly without reprisal. Dumont blocks a head kick, and she hunts for her overhand when Chiasson is kicking at her. Dumont reaches out with two punches, but Chiasson is out of range and dodges. Chiasson stings her with a right hand, and Dumont wobbles her knees and slings a right back her foe’s way. Chiasson steps in with a left hand, and she dodges and slips a right hand to hit a takedown as Dumont attempts to spin. The round ends right after the ladies hit the ground.

The featherweights clap hands to start off Round 2, and Chiasson is ready to throw a head kick. It partially gets through, and Dumont responds with a front kick only to get kicked back. Chiasson navigates at her own range, keeping Dumont guessing and staying active enough to shut down Dumont’s typical hard-charging offense. Dumont lands a solid right hand when getting kicked, and Chiasson slides back and chops at the knee with her shin. Chiasson keeps moving and has a leg kick checked, leading her to shoot in to get hold of a body lock and try to take the fight down. Tying Dumont up against the fence, Chiasson pursues a single down low, but the Brazilian stands tall and keeps herself on her feet. Chiasson muscles her down to the ground, and as Dumont leans forward to try to get up, Chiasson looks to take her back. Chiasson does not get her hooks in, and instead falls over when Dumont turns. Chiasson manages to fight her way back up again, not willing to stay grounded when Dumont plants her on her backside. Chiasson lands a few middling knees to the thigh as she holds Dumont in this position, and she grinds her foe until she trips her down. Chiasson falls to her back when trying to take her opponent down, and she gets back up when Dumont cannot hold her there. Chiasson knees Dumont in the chest as she clinches her up and pushes her to the wall, and the color commentators of Joe Rogan and Daniel Cormier relentlessly bash the ladies competing while essentially stating that they are nowhere near championship-level fighters. As they do, Chiasson tries for a trip, and she settles to lean heavily to keep Dumont pinned there until the disappointing round ends.

Round 3
There is a touch of gloves to start off the last round, and Dumont opens up with a left hand that rings Chiasson’s bell. The Brazilian continues her assault with a few punches that rattle Chiasson, and force Chiasson to take her down. Dumont gets back up, shoved to the wall, and dragged back down with a single from Chiasson. Dumont once more returns to her feet, and Chiasson holds on tight while trying to get her bearings back after getting tagged in the opening seconds. The crowd begins to loudly voice its disapproval as Chiasson grinds her foe into the wire, and Peterson asks them to keep working. Chiasson fails to get a takedown, but she settles for a knee up the middle and gets popped with a right hand. When eating that punch, Chiasson charges again to take her down. Dumont is only on her back for a few seconds before walking up the wall, and Chiasson hangs on to her in that position again. The crowd lets them have it as Chiasson embraces the grind, and Peterson lets them keep at it as Chiasson delivers a plethora of short knees to the thigh. Seeing that Peterson will not step in, Dumont tries for herself to score a knee up the middle. Chiasson goes for a trip, and it fails, allowing Dumont to fall on top of her. They both stand up, and Chiasson throws a head kick recklessly. While Chiasson has her leg in the air, Dumont gets off two stinging punches that rock Chiasson again. Chiasson dives desperately for a double, hurt again from the blows and totally fatigued, and all she can do is push Dumont to the wall. Chiasson allows control time to rack up as she hangs on, and Dumont gets hold of the neck and sets up a guillotine choke with seconds left in the round. Chiasson punches the thigh repeatedly to no effect, and the grueling, exhausting fight finally ends as they are clinched up.

Norma Dumont

Big Brady picks Norma Dumont to win by decision. He believes Dumont is the more well-rounded fighter with good striking and grappling. Chiasson has a size advantage in height and reach, but her takedown defense is a liability, as seen against Renaud and Lansberg. Dumont can mix in takedowns and control Chiasson on the mat. Brady thinks the line is wide but agrees Dumont should be the favorite. He expects a competitive fight on the feet but Dumont's path to victory is through takedowns and control.

Norma Dumont

Cody picks Norma Dumont but is not confident at -225. He notes that Chiasson is moving up to 145 and has defensive liabilities. Dumont has a slight grappling and striking advantage, and her technical boxing is sharper. However, Cody thinks the price is too high and that the fight is closer to a coin flip. He will keep an eye on weigh-ins.

Norma Dumont

The host picks Norma Dumont, believing she is the better striker and physically strong enough to negate Chiasson's bullying style. He notes Chiasson's success comes from being the bigger fighter, but Dumont is thick and strong. He expects Dumont to land the more significant strikes and possibly get a knockdown. He is not keen on betting Dumont at -220 but prefers the decision prop at +100. He also likes 'fight goes to decision' at -220.

Raquel Pennington

Angelo picks Raquel Pennington but thinks the odds are too wide. He notes that Pennington is a grinder who uses cage control and pressure, but that Macy Chiasson uses her reach well and has good Muay Thai. He believes the small cage at the Apex may limit Chiasson's ability to circle, but still sees Chiasson as a live underdog. Angelo expects a boring win for Pennington but not a cakewalk.

"i think raquel is able to crowd pressure and work her way to a pretty boring win but this is not a cakewalk"

Macy Chiasson

Big Brady initially liked Pennington but changed his pick after learning the fight is at 145 lbs, which he believes massively favors Chiasson. He notes Chiasson's size, youth, and experience at featherweight, and expects her to use her height and reach to win a close decision. He mentions Pennington's takedown ability but thinks the weight class change is decisive.

Cody likes Chiasson as a dog, noting the fight is at 145 lbs which favors her. He points out that Pennington has looked disinterested since her title fight and has poor striking. Chiasson is bigger, stronger, and has better striking at range and in the clinch. Cody thinks Chiasson can win by outworking Pennington.

Daniel Levi Expert Lean picked Dec 16, 2021 (2 days before fight)
Raquel Pennington

Daniel Levi slightly leans toward Raquel Pennington. He praises Pennington's grit, durability, and experience, noting she only loses to former champions. However, he points out that many of Pennington's wins are split decisions, making it a close fight. Levi is concerned about Chiasson's size and reach advantage at 145, and wonders if Pennington's clinch game will be less effective against a taller opponent. He thinks Chiasson could win if she has improved, but ultimately picks Pennington to edge out a decision.

Jacob picks Macy Chiasson, believing the UFC is setting her up to be a contender. He thinks the fight comes down to clinch work, and that Chiasson is bigger, more physical, and nastier than Pennington at this point. He expects Chiasson to win a dirty decision, possibly with a finish. Jacob notes that Chiasson has never been finished and has finishing ability herself.

Ailín Pérez

Angelo is shocked that Ailín Pérez is only a -165 favorite, believing she should be a -300 favorite. He highlights Pérez's relentless takedowns and pressure, noting that Macy Chiasson gets taken down easily and has been on a losing skid. He expects Pérez to shoot takedowns and win a decision, especially with the Mexican judges favoring aggression.

He compares Macy Chiasson to 'female Phil Rowe,' noting she is big but ineffective and can be controlled on the ground. He believes Pérez can take Chiasson down and win the first two rounds, but the third could be sketchy. He predicts a decision win.

Diary of a Pro Gambler Expert Hesitant picked Feb 28, 2026 (fight day)
Macy Chiasson

The host is betting on Chiasson despite her inconsistency because the odds are too wide. He believes Chiasson is better than Pérez everywhere: she has a huge size and reach advantage, is a better striker and grappler, and has superior cardio. However, Chiasson has self-destructive tendencies and bad fight IQ, making her unreliable. The host caps the fight at 50/50 because Chiasson only shows up half the time, but at +149, the value is too good to pass up. He also notes Pérez's cardio may suffer at high altitude.

"There's no way Chersison should be an underdog in this fight. The odds just don't make any sense at all. ... Problem is quite often Chazon doesn't show up."
LU
Lucrative James Expert Confident picked Feb 22, 2026 (6 days before fight)
Ailín Pérez

James favors Pérez due to her wrestling and top control, which should neutralize Chiasson's striking. He notes Chiasson's confidence issues and tendency to wilt when pressured. James predicts Pérez wins by decision, though he admits bias as he knows Pérez personally.

"My pick will be E Island Perez to win this fight. Most likely via decision."

Paul expects Pérez to use her wrestling to control Chiasson, who struggles with weight cuts and cardio at altitude. He sees a decision win for Pérez and recommends waiting for weigh-ins to confirm Chiasson's condition.

"AFP by boring stalling uh wrestling clinic and then somehow she'll be like borderline top 10 fighter at that point."

He notes that Macy Chiasson looked bad in her last fight against Irene Aldana, and he believes Pérez can take her down and control the ground. He predicts a 29-28 decision win, acknowledging that Pérez has been improving and has a strong build for the division.

Zane Simon Expert Confident picked Feb 27, 2026 (1 day before fight)
Ailín Pérez

Zane picks Pérez because she is mentally consistent, has a clear winning game plan, and sticks to it. He notes that Chiasson is bigger and more powerful but breaks down mentally and physically. Pérez's takedown game and high motor should wear on Chiasson, who has a weak core and struggles with leverage.

Chiasson opened at -110, now +155; Pérez opened at -110, now -180. Zane calls these sensible odds.
"I'll take Perez too. I just think she seems very mentally consistent from one round to the next one minute to the next."
