Umar Nurmagomedov and Song Yadong headline in Shanghai, but the value on this card lives in a flyweight rematch nobody saw finish the first time.
Umar Nurmagomedov against Song Yadong is the marquee fight on this Shanghai card, a bantamweight clash that'll get the pop and the attention it deserves. That's not where this column is going, though. Thirteen bouts deep into a card, our model only found one fight where it had full data on both sides and enough disagreement with the market to actually put a number on it. Everything else got skipped on purpose — no half-guessed profiles here. The one that cleared the bar is a flyweight rematch with a genuinely strange asterisk on it: Alex Perez and Sumudaerji already fought in May, and it ended in a No Contest. Both guys list that fight as their most recent bout. Nobody got a resolution. Now they're doing it again, and the market has opinions about who wins the sequel that our model doesn't fully share.
Our model gives Alex Perez a 55% win probability here, against a market implied number of 36% at a price near +180. That's a 19% edge — and let's be honest about what that means. A gap that size against a book that prices flyweight fights for a living is either a real inefficiency or the model is just wrong. Grade A+ doesn't mean lock. It means the model is willing to plant a flag and disagree loudly. Treat it as an aggressive value swing, not a sure thing.
The stylistic frame is straightforward: our model tags both men as strikers, so this is a stand-up fight decided by output and defense, not a wrestling clinic. On paper Sumudaerji has the sharper hands in volume — our striking model credits him with 3.992 significant strikes landed per minute compared to Perez's 3.296 — and our matchup math also has Sumudaerji ahead in strike defense. Takedown defense is a wash between them, both sitting at 73% per the model. Where Perez claws back ground is exactly where you'd want him to: our matchup math has him ahead in takedown offense, giving him a route to change levels and problems if the striking exchanges aren't breaking his way. Freshness is a non-issue too — both guys are roughly three months removed from their last outing, so nobody's shaking off rust the other isn't.
The finish equation favors Perez in a way that matters for a fight the model leans toward going long. His finish profile marks him as a genuine finisher who closes out most of his wins, and the model's method lean here — 32% KO/TKO, 20% submission, only 48% decision — reflects a live finish path even in a fight tabbed to go the distance 48% of the time. Sumudaerji's profile reads as a decision fighter whose recent wins have gone to the scorecards, which tracks with a run that includes a decision win over Jesus Aguilar, a decision over Kevin Borjas, and a split decision over Mitch Raposo. Perez, for his part, has closed the show recently too — a first-round KO/TKO finish over Charles Johnson back in January, a second-round KO/TKO over Matheus Nicolau last April. He's also been on the wrong end of stoppages, per his finish profile, which is the honest caveat here: he's gettable when things go badly, having been finished by submission against Asu Almabayev and by KO/TKO against Tatsuro Taira in his last five. This isn't a fighter without holes.
Our internal Glicko rating has Perez rated higher, by 258 points, which lines up with the pick rather than fighting it. Combine that with a live finishing threat against a decision-oriented opponent, a rematch scenario where nothing was actually settled the first time, and a market number that looks light relative to what the model sees, and this is the one bet on the card worth taking seriously — with eyes open about the size of the number the model is disagreeing with.
Everything else on this Shanghai lineup, including the Nurmagomedov-Song main event, simply didn't clear our data threshold for a published number — that's by design, not an oversight. When the model doesn't have both sides covered, it stays quiet instead of guessing. The flyweight rematch is the lone released pick, and it's an aggressive one. Bet sizing should reflect that a 19% edge is a strong signal, not a guarantee.
