Xander Zayas

Bio

Xander Zayas is the unified WBO and WBA junior middleweight champion, and at just 23 years old he is one of the most exciting young fighters in the entire sport. The Puerto Rican is 23-0 with 13 knockouts, and in January 2026 he unified the division by edging Abass Baraou on a split decision — becoming the youngest unified ruler in boxing and the first Puerto Rican to unify at 154.

What makes Zayas so special is his maturity. He boxes like a fighter a decade older than he is — patient, behind a beautiful jab, picking his shots and refusing to panic when a fight gets tight. He has carried the weight of Puerto Rican expectation since he turned pro as a teenager, and rather than buckle under it, he has thrived. The lad has announced himself as the real deal.

He is not a one-punch knockout artist, but he does not need to be. Zayas wins rounds, controls range, and grinds opponents down with volume and ring IQ. His detractors point to that modest knockout ratio, but at this weight and at this level, the ability to win the rounds you need to win is worth its weight in gold.

Now comes the defining test of his young career: a June 27 defence against Jaron 'Boots' Ennis at the Barclays Center in Brooklyn. Beat a 35-0 monster like Ennis and Zayas does not just keep his belts — he confirms himself as one of the very best pound-for-pound talents the sport has to offer. This is his moment to truly arrive on the world stage.
