Key points
- Jaime Munguía is a 29-year-old Mexican boxer from Tijuana, a former two-division world champion known for relentless pressure and a granite chin
- He won the WBO junior middleweight title by stopping Sadam Ali in 2018, aged just 21, and later added the WBA super middleweight title in May 2026
- His only two losses came against Canelo Alvarez by decision and Bruno Surace by shock knockout
- His team is reportedly weighing whether to vacate the WBA super middleweight title rather than face mandatory challenger Bektemir Melikuziev
Tijuana’s produced plenty of come-forward fighters over the years. Munguía’s built a career out of being the toughest version of that – and now his own team’s weighing up giving away a belt rather than defend it.
A teenager who started fast and never really slowed down
Munguía turned professional at just 16, training under his father before working his way through a string of Mexican trainers, from Robert Alcázar to Erik “El Terrible” Morales, then a spell with Freddie Roach, and now Eddy Reynoso – the same man in Canelo’s corner. Twenty-eight straight wins got him a world title shot at 21, and he took it, stopping Sadam Ali in the first round to win the WBO junior middleweight belt in March 2018.
All action, all the time – for better and worse
What made him a fan favourite early is what’s made him vulnerable late: he comes forward, he trades, and he doesn’t take a backward step even when it’s the smart move. Alcázar spent years trying to get him to lean on his jab rather than simply walk through opponents. It never fully stuck. Munguía’s best work still comes from establishing the body early, then grinding an opponent down as the fight goes on.
Canelo exposed the gap, Surace confirmed it
Munguía’s only two losses tell the real story. Canelo Alvarez dropped him and won a clear decision in May 2024, the kind of result that comes from facing a genuinely superior boxer rather than just a bigger puncher. Then Bruno Surace knocked him out in a fight he was favoured to win comfortably – proof the chin that carried him through 46 wins isn’t actually unbreakable.
Why he’s suddenly thinking about walking away from a title he just won
Munguía added the WBA super middleweight belt in May 2026, only to now face Bektemir Melikuziev, a compact, heavy-handed southpaw with the exact kind of pressure that’s already found the cracks in his game twice. The WBA’s given both camps until October 21 to reach terms before it goes to a purse bid. Vacating dodges a fight built to expose him again. It also hands back a title he only just got his hands on – not exactly the legacy a fighter with his fanbase usually wants attached to his name.
