BETTING PREVIEW | SCOUTING REPORT | ODDS: Santos (-142), Yoo (+120)

Round 1
Whether because one or both were going to miss weight badly, this featherweight contested shifted to a catchweight at 153 pounds. Santos (13-2, 3-1 UFC), who has come in heavy before, will benefit from this relocated weight category as he comes in likely the larger of the two. Yoo (9-0, 1-0 UFC) is fine with the switch, because he just wants to put hands on faces. He will just as soon as referee Herb Dean clocks them in, and the two bump fists. Now it’s time for some face-punching.
Yoo sneaks out a low kick, and he jumps away to dodge a counter kick and plants one more on the same spot. Santos just misses with a spinning wheel kick, and Yoo springs to the side and flicks out a jab. Yoo leaves a right hand out too long, and Santos just misses on the counter. A quick high kick comes from the Brazilian, and he attempts to time a jab with a chopping calf kick. Santos aims and comes up short on a body kick, and he spins with more kicks that keep missing. Yoo busts him in the chops with a knee up the middle, and his right hand and low kick further do damage. Santos comes out swinging back, and “Zombie Jr.” beats him to the punch with his piston-like jab. Santos leaps after him and catches him with a punch or two, and Yoo claps at him to celebrate.
Santos spins and misses, and Yoo showboats and does his own little twirl. Santos punches his way into a double-leg takedown, scoops the South Korean off his feet and taking the excitement out of the crowd. Santos headbutts Yoo in the chest a couple times, and Dean tells him he has to stop doing that. Yoo puts his hand by his face to mime that he is resting, and Santos keeps trying to control him. Santos looks to grind Yoo down like a mortar and pestle, grating and draining him all while Yoo motions that he is bored. Yoo fights to his feet, and the fans respond in kind. Yoo jams his man in the torso several times with kicks, and his hands are wide as he snaps out jabs. Santos dips down and wings a right hand, and Yoo laughs it off. Yoo lands, and Santos fires back harder. The impact of Santos’ blows is much more measurable, while Yoo would prefer to just touch and get away. Yoo slaps Santos in the face, and Santos pays him back with hard hooks. The South Korean peppers the front leg with kicks and dodges a wheel kick as the horn sounds.

Round 2
Yoo starts the round elusive as can be, zipping from side to side and tagging Santos with long punches. Santos is angered by this bull-matador approach, and he blitzes the South Korean. Yoo parries two punches,
and the third, a sweeping left hook from the Brazilian, smashes square into Yoo’s jaw. Yoo collapses to the ground on his knees, and Santos batters him with an onslaught of right hands to finish the job. Yoo appears frustrated that he got caught until his expression changes from the standing-to-ground blows he is absorbing, and it does not take much more than that for Dean to intervene
. Just like that, “Zombie Jr.” has been drummed out of the ranks of the unbeaten, and Santos notches a huge win with style points and runs to greet Mark Zuckerberg sitting cageside.

Daniel Santos def. Joo Sang Yoo R2 0:21 via TKO (Punches)

AN
Angelo Bodetti Expert Confident picked Sep 28, 2025 (6 days before fight)
Daniel Santos

Angelo picks Daniel Santos despite the public heavily favoring Yoo Joo-sang (77% on Tapology). He believes Santos has quality wins and has proven himself in the octagon, while Yoo's only notable win is against a weak opponent. He is surprised by the public confidence in Yoo and trusts Santos as the slight favorite.

"I'm going to pick Daniel Santos here. He is the slight favorite, which is why I was surprised to see everybody on the other side."
BI
Big Brady Expert Confident picked Oct 2, 2025 (2 days before fight)
Daniel Santos

Big Brady acknowledges that this is the closest line fight on the card and that there is missing information on Yoo Joo-sang. However, he notes that Santos has been mixing in wrestling effectively in his recent fights, completing over 10 takedowns in his last three. He believes Yoo Joo-sang is too hittable and gets taken down too easily. He predicts Santos wins by decision, using his wrestling to dictate the fight.

"I'm going to take Daniel Santos here for the pick. I'm going to take him to win this fight by decision."
CO
Connor Ruebusch Expert Confident picked Oct 3, 2025 (1 day before fight)
Daniel Santos

Connor agrees with Zane, picking Santos because he sees Yoo as a raw talent who has not been forced into a brawl and may struggle when Santos puts together multiple attacking ideas. Connor notes that Santos is a dark horse who is more difficult to face than he looks, and he expects Yoo to have initial success but then get caught by Santos's persistent pressure.

Santos opened at -150, currently -141; Yoo opened at +130, currently +121
"I think you gotta go with Santos here."
MM
MMA Lock of the Night Expert Confident picked Oct 4, 2025 (fight day)
JooSang Yoo

Santos missed weight and asked for a catchweight, indicating his body wasn't responding. The host believes Yoo Joo-sang can take advantage by counter-striking a reckless Santos or chipping away for a decision win.

"I think you should be able to take advantage of that either by counter striking Santos, who will likely come out with a reckless approach, or chipping away at him and winning this fight on the scorecards."
TH
The MMA Guru Expert Confident picked Oct 1, 2025 (3 days before fight)
JooSang Yoo

The MMA Guru picks Yoo Joo-sang, believing his counter-striking and power will be too much for Daniel Santos. He notes Santos's tendency to get hit while closing distance and his inactivity. He predicts a first-round KO.

first-round KO
"I'm going to go with Juesung Yu getting this one done. I reckon he chins Daniel Santos in round one."
ZA
Zane Simon Expert Confident picked Oct 3, 2025 (1 day before fight)
Daniel Santos

Zane picks Daniel Santos because he believes Santos is a volume brawler who mixes in takedowns and holds his ground in the pocket, while JooSang Yoo, despite his raw talent and speed, has not faced real resistance and tends to drop his hands and lean back out of the pocket, leaving him vulnerable to Santos's combinations. Zane notes that Santos has never been KO'd and is durable, and he expects Santos to catch Yoo off guard with sustained offense.

Santos opened at -150, currently -141; Yoo opened at +130, currently +121
"I think you gotta go with Santos here."

JooSang Yoo

Angelo picks Yoo Joo-sang very confidently, calling Jeka Saragih a bar brawler who sucks. He praises Yoo's fluid striking, confidence, and grappling. He thinks Jeka's only chance is a lucky punch, which he doesn't see happening. He parlayed Yoo with Azamat Murzakanov as his two most confident picks.

BI
Big Brady Expert Confident picked Jun 3, 2025 (4 days before fight)
JooSang Yoo

Big Brady picks Yoo Joo-sang, noting his solid striking and grappling. He thinks Jeka Saragih is dangerous early but will fade, and that Yoo will mix in takedowns and break Saragih in the second or third round. He calls Saragih's win over Lucas Alexander a fluke and doubts he will win another UFC fight. He predicts Yoo by second-round submission.

MM
MMA Lock of the Night Expert Confident picked Jun 4, 2025 (3 days before fight)
JooSang Yoo

This is considered a squash match for Yoo Joo-sang. As long as he avoids Saragih's early power, he will take the fight to the ground quickly and find a finish within one round. The pick is for Yoo Joo-sang via TKO or submission in round one.

TH
The MMA Guru Expert Hesitant picked Jun 4, 2025 (3 days before fight)
JooSang Yoo

The MMA Guru picks Yoo Joo-sang but is hesitant, noting his padded record against weak opponents. He acknowledges Jeka Saragih has power and a chance to KO, but Saragih is easy to take down and has bad losses. He bets on Yoo's recent improvement and finishes, predicting a first or second round finish. He sees value on Saragih as an underdog.

Odds comment: Yoo is a 5-to-1 favorite. Finish prediction: first or second round finish for Yoo. Value on Saragih as underdog.
"I'm going to go with Juan. Undefeated, looked good in his last few. Had some finishes over some decent recorded opponents."
