CO
Connor Ruebusch Expert Confident picked May 8, 2026 (1 day before fight)
Ateba Gautier

Connor agrees that Gautier is being well-managed and that this fight is a showcase. He highlights that Diaz is a 'normal guy living his dream' who lacks the athleticism to compete with Gautier. Connor notes that Diaz's losses come from being 'absolutely fucked up as fast as possible' and expects Gautier to crush him.

DA
Daniel Vreeland Expert Confident picked May 8, 2026 (1 day before fight)

DI
Diary of a Pro Gambler Expert picked May 8, 2026 (1 day before fight)
No clear pick

The host does not bet this fight. He notes Gautier is a huge favorite (1.09) and unplayable, while Diaz is weak on the ground. He considers the over 1.5 rounds at 3.50 tempting but decides to protect his money.

No bet. Mentions over 1.5 rounds at 3.50 as tempting but passes.
"I wouldn't touch Aussie Diaz here, but obviously Gautier's odds are unplayable... I'll probably give this a miss."
FI
FightingPost AI Expert Lock picked May 9, 2026 (fight day)
Ateba Gautier

Predicted method: KO/TKO Round 1. Gautier is undefeated with four first-round finishes, showcasing devastating KO power and a 100% takedown accuracy. Diaz has only one win and was knocked out in his UFC debut, absorbing 7.23 strikes per minute. Gautier's reach advantage (81" vs 79") and switch stance will create problems for Diaz, who has no takedown attempts in his career. This is a massive mismatch; Gautier will likely land a clean shot early and finish the fight within the first round.

LU
Lucrative James Expert Confident picked May 3, 2026 (6 days before fight)
Ateba Gautier

"I got a TB Goautier to win this fight via knockout in round one."
MM

ZA
Zane Simon Expert Confident picked May 8, 2026 (1 day before fight)
Ateba Gautier

Zane sees this as a showcase for Gautier, who is being carefully managed. He notes that Ozzy Diaz is a tough, hard-nosed fighter but lacks the athleticism and dynamic offense to threaten Gautier. Zane believes Gautier's superior athleticism and technique will overwhelm Diaz, especially since Diaz tends to get crushed quickly when facing better athletes.

Gautier opened at -1000, now -1800; Diaz opened at +675, now +900. The odds reflect the matchup dynamic.
"showcase for Gautier, nothing wrong with this man getting the showcase at this point in his career."

Mingyang Zhang vs. Osman Diaz

Round 1
The main card has begun, and all the Road to UFC fights are behind us. It’s time for some action. Light heavyweight finishers that sport matching 100% stoppage rates come to blows, and referee Kevin Sataki better fasten his safety belt. Zhang (17-6, 1-0 UFC) has the crowd behind him and a ton of momentum with 10 straight knockouts at his back. LFA vet Diaz (9-2, 0-0 UFC) will certainly not shy away from a brawl, and it could get wild in a hurry. The two clap their hands together, and it is Zhang who moves directly to the center of the cage. The fans are energized and chanting support for “Mountain Tiger,” who leads the dance with a push kick and then two calf kicks. Diaz leaps forward with a left hand that is blocked, and he ducks down and nearly gets kneed. Zhang splits the guard with a leaping left hand, and Diaz lunges at him back with a jab. Diaz’ jab is countered by a few leg kicks, and Zhang reaches him with a left hand up top. Diaz scores a right hand to make the Chinese fighter smile, and Zhang races after him loaded for bear. Diaz backs him off with an overhand right, and he slips away from a body jab but cannot get out of the way of a one-two. Diaz plunks his foe with a right hand around the guard, and Zhang smiles and resets.
Zhang hammers the front leg, and he nails Diaz with a short but devastating elbow that puts Diaz down. Barely still with it, Diaz turns to his knees and turtles up, and the man from China rushes after him to pummel him. About a dozen swarming punches get through from Zhang before Sataki has seen enough
, and Zhang’s 100% finish rate—all in the first round—stays intact by crushing the LFA vet. The crowd goes wild.

AN
Angelo Bodetti Expert Confident picked Nov 17, 2024 (6 days before fight)
Zhang Mingyang

Angelo picks Zhang Mingyang, citing his superior grappling and power. He notes Ozzy Diaz is chinny and skinny, and expects Zhang to finish inside the distance. He suggests looking for extra juice on Zhang inside the distance.

Zhang inside the distance; fight won't go to distance
"Jiang is going to be the pick here you're probably safe to try to find a little extra juice like Jiang inside the distance"
BI
Big Brady Expert Confident picked Nov 20, 2024 (3 days before fight)
Zhang Mingyang

Big Brady picks Zhang Mingyang to win by first-round knockout. He thinks the odds are off but notes Ozzy Diaz is very hitable and has a questionable chin, often getting beaten up before mounting a comeback. Zhang has tremendous power and is likely to land early. Brady expects a violent first-round finish, as Zhang has never won a fight that went past the first round.

Zhang Mingyang wins by KO in round 1
"I think the most likely scenario is a jang mingyong first round knockout and that's what I'll go with"
CO
Cody Saftic Expert Confident picked Nov 20, 2024 (3 days before fight)
Ozzy Diaz

Cody picks Diaz as a live underdog, arguing that Zhang's record is built on weak competition and he has been knocked out or submitted in most losses. Diaz has fought better competition, trains at Kings MMA, and has power and a ground game. He expects a banger where Diaz's experience and durability give him the edge, possibly by knockout.

"I would take aie Diaz yeah I can't really disagree with very much there it just seems it's like an absolute car crash"
CO
Connor Ruebusch Expert Hesitant picked Nov 21, 2024 (2 days before fight)
Zhang Mingyang

Connor picks Zhang but hesitantly, noting that Diaz's pressure and composure could take Zhang into the second round, where Zhang historically loses. He acknowledges that King's MMA fighters often overperform and Diaz could survive the early storm. However, Connor thinks Zhang's power and brawling are a good answer for Diaz's style, and he's not ready to fade Zhang yet.

Same odds commentary as Zane.
"I think he's a very reasonable pick as well. But you know how loathe we are to trust first-round knockout machines."
DA
Daniel Vreeland Expert Confident picked Nov 21, 2024 (2 days before fight)
Zhang Mingyang

Daniel Vreeland picks Zhang Mingyang, a Chinese knockout artist on a 10-fight win streak. He notes Diaz's tendency to get beaten up early before opponents gas, but believes Zhang will not gas out and will finish him. Vreeland highlights Zhang's devastating ground and pound and chin-finding ability, expecting a knockout in Macau.

Paul Shaughnessy Expert Confident picked Nov 20, 2024 (3 days before fight)
Ozzy Diaz

Paul agrees, noting that Zhang's wins are over nobodies and his losses are by finish. Diaz has trained with high-level partners and has power in his hands. He thinks the plus money is worth a shot in a volatile matchup where both have knockout power, but Diaz's superior competition gives him the edge.

"give me the guy who trains it with a good gym in California get good looks I mean it comes down to Who's Who skull can take you know who can who who skull can take a concussive blow"
TH
The MMA Guru Expert Confident picked Nov 21, 2024 (2 days before fight)
Zhang Mingyang

The MMA Guru picks Zhang Mingyang over Ozzy Diaz, citing Zhang's power and finishing instincts. He notes Zhang knocked out Branson Ribero in his debut and knocked out Tokotos on Road to UFC. He views Diaz as a 'skinny fat' athlete who got smoked by Joe Pyfer and has a questionable win over Bavon Lewis. He predicts a first-round TKO for Zhang.

ZA
Zane Simon Expert Confident picked Nov 21, 2024 (2 days before fight)
Zhang Mingyang

Zane picks Zhang Mingyang, citing his brawling power and first-round finishing ability. He notes that Diaz is a functional pressure fighter but lacks elite athleticism, and Zhang's power could put him away early. Zane acknowledges that Zhang is a first-round knockout machine and usually loses if he goes past the first, but Diaz's style plays into Zhang's strengths.

Diaz opened +253, now +273; Zhang opened -301, now -329. Zane says 'these odds should not be getting wider' and 'Zhong is not that guy to have wide odds.'
"I'm going to take Zhang Mingyang just to land the kind of shots on Diaz walking in that have put Diaz to sleep before."
