Luis Felipe Dias vs. Yi Sak Lee
BETTING PREVIEW | SCOUTING REPORT | ODDS: Dias (-170); Lee (+140)

Round 1
The top prelim of UFC Macau sees yet another pair of newcomers, as Dias (17-5) and Lee (8-1) meet in a middleweight clash. Both fighters are in orthodox stance, and they meet in the middle of the cage at a word from referee Lukasz Bosacki. Both fighters are very wary in the early going, and it’s well over 30 seconds before Dias is the first to commit to a hard strike: a left leg kick. Lee answers with one of his own, and he starts to get busier with his hands. Lee throws a low kick and Dias tries unsuccessfully to trap the leg. Dias lands a leg kick, slips the counterpunch and lands a punch of his own. A moment later he does it again, going first and third, and the punch sits Lee down. Dias lets Lee pop back up and they go back to work. Lee lands a leg kick, but his strikes are starting to come at three-quarter speed, likely in anticipation of Dias’s counter.
Under two minutes to go, and Dias crushes Lee with a short right hand that drops him to his knees once again. Dias swarms with punches and two or three get through. Bosacki dives in for the stoppage, which looks as if it might be quick, but Lee is shaky as he stands and makes only a token protest.
Violent work by the Brazilian newcomer.

AJ
AJ DeVito Expert Confident picked May 26, 2026 (4 days before fight)
Luis Felipe Dias

AJ picks Diaz because of his freakish physicality and pressure fighting. He notes Lee had a loss to a journeyman and looks unathletic, while Diaz is a bully with strong ground skills. AJ thinks Diaz will outwork Lee physically, possibly via ground and pound or submission, and that Lee won't have the tank to survive Diaz's early strength storm.

AN
Angelo Bodetti Expert Lean picked May 27, 2026 (3 days before fight)
Luis Felipe Dias

Angelo leans towards Diaz because he is stronger and lower to the ground, making it harder for Lee to get takedowns. He thinks Diaz will get his own takedowns and work ground and pound. However, he cannot bet due to too many unknowns.

"I'm going to slightly lean Diaz here because despite him being the smaller fighter in stature, I think he's stronger."
AN
Angelo Bodetti Expert Lean picked May 24, 2026 (5 days before fight)
Luis Felipe Dias

Angelo slightly leans toward Luis Felipe Dias, believing his strength and lower-level takedown will be effective against Yi Sak Lee's bully style. He notes that neither fighter is a good wrestler, but he thinks Dias's grappling and willingness to bomb on the feet give him the edge. He cannot bet on this fight due to too many unknowns.

"I am going to slightly lean Diaz here. Diaz is it?"

Luis Felipe Dias

Angelo picks Luis Felipe Dias, believing he can control where the fight goes with his takedowns. He notes both fighters are grapplers with mediocre wrestling, but Dias's shorter, thicker build may give him an advantage in shooting first.

BI
Big Brady Expert Confident picked May 26, 2026 (3 days before fight)
Luis Felipe Dias

Big Brady picks Luis Felipe Dias by first-round submission, despite calling the fight potentially the lowest level in UFC history. He notes Dias has a huge grappling advantage and is a black belt, while Yi Sak Lee is one of the worst grapplers he's ever seen, losing to a 'hot dog vendor.' He warns that Dias has terrible cardio and if the fight goes past the first round, the bet looks bad.

Cody Saftic Expert Confident picked May 27, 2026 (2 days before fight)
Luis Felipe Dias

Cody picks Dias despite acknowledging he is not a great fighter. He notes Dias' physicality, power, and size advantage. Lee comes from a judo base but has poor striking and lacks explosion. Cody believes Dias will land a big shot or use his strength to win. He is concerned about Dias' PED use but thinks he is good enough to win.

CO
Connor Ruebusch Expert Confident picked May 28, 2026 (1 day before fight)
Luis Felipe Dias

Connor agrees with Zane, picking Luis Felipe Dias. He acknowledges Yi Sak Lee could be a secret super-soldier but considers it unlikely. Dias is the experienced, finished product, while Lee's career has been hidden because he is not ready.

"I will take the experienced guy, Luis Felipe Dias."
JA
Jacob Lines Expert Lean picked May 27, 2026 (3 days before fight)
Yi Sak Lee

Jacob picks Lee as a dog because he was unimpressed with Diaz in his Contender Series fight, noting that Diaz struggled against a low-level opponent and gassed. He thinks Lee can weather the early storm and possibly finish Diaz.

"I'm taking a shot on the dog here just because I was very unimpressed with Luis Diaz."
LU
Lucrative James Expert Confident picked May 23, 2026 (6 days before fight)
Luis Felipe Dias

Lucrative James is very confident in Luis Felipe Dias, calling Yi Sak Lee a 'very poor MMA fighter' with no discernible skills. He notes Dias' good jiu-jitsu and physical wrestling, while Lee has poor boxing, takedown defense, and was submitted in his last loss. He predicts Dias will win via submission easily, despite Dias' cardio and bodybuilder build concerns.

Luis Felipe Dias via submission
"I can't pick anyone else but Luis Felipe Diaz. So, yeah, Luis Felipe Diaz via submission."
MM
MMA Lock of the Night Expert Confident picked May 25, 2026 (4 days before fight)
Luis Felipe Dias

The host picks Diaz, believing his striking and grappling defense will cause Lee to slow down faster. He notes both have cardio issues but expects Diaz to be the better striker and to find a knockout. He is not high on Lee's strength of schedule and thinks Diaz provides legitimate resistance.

"I'm going to go with Diaz here. I think he eventually finds a knockout over Lee."
MM
MMA Lock of the Night Expert Confident picked May 27, 2026 (2 days before fight)
Luis Felipe Dias

The host likes the Brazilian Luis Felipe Dias, believing he can stop the grappling of Yi Sak Lee and land big shots, potentially using his BJJ black belt. He predicts a knockout for Dias over the Korean newcomer.

by knockout
"I like the Brazilian in this spot as I believe he'll be able to stop the grappling of the Korean fighter and I think that will allow Diaz to really put it on Lee and I think we'll see him land this big shots. I think he could have success with this BJJ black belt as well, but I think it'll ultimately be a knockout for the Brazilian here over the Korean newcomer."

Paul Shaughnessy Expert Confident picked May 27, 2026 (2 days before fight)
Luis Felipe Dias

Paul agrees with Cody, calling Lee 'horrible' and noting Dias' physicality edge. He mentions Dias' jiu-jitsu and power. Paul is concerned about Dias' PED use but thinks he will win. He also notes that Lee's striking is poor and he relies on judo trips, which may not work against a bigger opponent.

"I kind of agree. I watched Eaceline. I was just like, 'This guy's horrible.' And at least we have a physicality edge in Luis Felipe Diaz."

The MMA Guru Expert Confident picked May 20, 2026 (9 days before fight)
Luis Felipe Dias

The MMA Guru picks Luis Felipe Dias to win by submission. He is surprised to be picking Dias, but believes Dias can outgrapple Yi Sak Lee, who has poor defensive grappling and cardio. He notes that Dias has put on muscle and despite his own poor striking defense, he should be able to submit Lee.

value at minus 155
"I think he's a lot of value at minus 155. Louis Fed is terrible. ... I think he's going to submit exactly."
TH
The MMA Guru Expert Hesitant picked May 20, 2026 (9 days before fight)
Yi Sak Lee

The Guru picks Youssouf Ly (Yi Sak Lee) in a tough fight, citing his judo background and better cardio. He believes Ly can survive Diaz's early bursts and take over late as Diaz fades. He notes both fighters are unproven but favors Ly's potential and durability.

"But I ended up going with Y Sauk Lee."
TH
The MMA Guru Expert Lean picked May 26, 2026 (4 days before fight)
Yi Sak Lee

The Guru picks Lee based on geographical advantage and grappling. He notes Lee is an aggressive striker with low hands but has good upper body throws and ground and pound. Dias has decent power and submissions but struggles to get takedowns and can be held down. He admits low confidence and calls it a 'grasping at straws' pick.

"I'm going to side with Lee because we're closer to the part of the world that he lives in and I feel like it's going to be less jet lag on him."
ZA
Zane Simon Expert Confident picked May 28, 2026 (1 day before fight)
Luis Felipe Dias

Zane picks Luis Felipe Dias because he has twice the experience and wins over more experienced opponents, while Yi Sak Lee has been carefully protected against low-level competition. Dias is a finished product with a powerful grappling game, though his striking is cumbersome. Zane notes Dias is undersized and not an exciting prospect, but he looks much more ready for this fight.

Odds mentioned: Dias -170, Lee +145
"I just have to take Luis Felipe Dias: he has twice the experience, wins over more experienced opponents, and looks much more ready for this kind of fight."
