He promised an emphatic debut. He delivered a career-defining one. David “El Monstro” Benavidez needed just six rounds to dismantle unified cruiserweight champion Gilberto “Zurdo” Ramirez at T-Mobile Arena, stopping the Mexican southpaw to become WBO and WBA Super Cruiserweight world champion on his very first night at 200 lbs. The Cinco de Mayo card got its headlining moment, and boxing got its next superstar with a belt — or two — to prove it.

Benavidez stopped Demetrius Andrade in Round 6. He stopped Gilberto Zurdo Ramirez in Round 6. The pattern isn’t coincidence — it’s the signature of a fighter who builds pressure so methodically that opponents arrive at the same breaking point regardless of their quality. The body work lands in the middle rounds, the guard drops, and then the right hand finds the opening. Zurdo, for all his southpaw craft and championship experience, followed the same trajectory.
What makes this result particularly striking is context. Zurdo entered the fight as a five-time cruiserweight winner with legitimate credentials: wins over Joe Smith Jr., Arsen Goulamirian, Chris Billam-Smith, and Mairis Briedis. He had never been stopped. His only loss — a points defeat to Dmitry Bivol in 2022 — came against a pound-for-pound great. He was not the kind of champion who folds easily.
And yet, Benavidez’s engine wore him down inside half the scheduled distance. The 81% KO rate carried into cruiserweight fully intact.
Benavidez arrived with 167 career rounds across 31 professional fights. Zurdo came in with 313 — nearly double, across a career spanning super middleweight and five cruiserweight title fights. That gap means Zurdo had absorbed vastly more accumulated punishment, more late rounds under pressure, more occasions where his body had been asked to sustain elite output past the midpoint of a fight.
From Round 1, Benavidez’s jab was shorter and sharper than Zurdo’s southpaw counter, and the body work — hooks downstairs, straight right to the ribs — started landing in Round 3. By Round 5, Zurdo’s work rate had visibly dropped. By Round 6, the engine had stalled and the referee had seen enough.
Benavidez becomes the unified WBO and WBA Super Cruiserweight champion in his first fight at the weight. That’s historically rare. The Canelo conversation, which defined Benavidez’s career for years as an absence rather than a fixture, now shifts. Benavidez is a unified cruiserweight champion, undefeated at 32-0, and the most destructive fighter in the division.
