LAS VEGAS – David Benavidez entered Saturday’s main event against Zurdo Ramirez with as much responsibility as he’s ever walked into the ring with, headlining the marquee for boxing’s de facto Super Bowl weekend during Cinco De Mayo in the city that is historically known as the Mecca of the sport.

To say Benavidez delivered would be an understatement. The “Mexican Monster” put together one of his finest performances to date, finishing Zurdo with a series of thunderous blows to the eye region that dropped the defending champion to one knee and rendered him unable to continue. The victory makes Benavidez the first boxer in history to win the 168, 175 and 200 pound titles and he achieved the feat seven months ahead of his 30th birthday.

The fourth round in particular will become a staple of Benavidez’s career highlight reel, as he effortlessly battered Zurdo and left him with what appeared to be a broken nose before finishing the round with his first knockdown. Zurdo was saved by the bell and bought himself some extra time with a solid fifth round, but the damage he sustained in the fourth was ultimately what did him in at the end.

The co-main event saw challenger Jamie Munguia register a lights out performance to take the WBO Super Middleweight Title from Toro Resendiz by unanimous decision, thoroughly beating his countryman on the cards 120-108, 119-109, 117-111 after a year-long absence from the sport due to an inconclusive drug test following his May 2025 win over Bruno Sarace. The night was certainly a statement for Munguia, who controlled the entire fight and would have probably left with a late knockout if he had a little bit more power left in his tank during the 11th and 12th rounds.

"Everything went exactly as we had it contemplated before the fight," Munguia said. "I wanted to KO him, but everything was outstanding. I had Resendiz against the ropes. I was on the verge of knocking him down in that last round. We tried our best to knock him out, but it wasn’t meant to be and the win was ours."

Munguia was supported at the fight by teammate and one-time opponent Canelo Alvarez, who was outfitted in the victor’s merchandise. Like Benavidez, Resendiz entered Saturday’s fight with his sights set on a potential bout against Canelo if he were to beat Munguia, but the defending champion’s performance left little to be desired and justified the relatively long odds he entered the fight with.

Oscar Duarte defeated Angel Fierro in a controversial split decision (116-112, 115-113, 112-116), capitalizing on a fourth round knockdown that allowed him to withstand a furious charge from Fierro in the sixth and seventh that at the time appeared to be just what Fierro needed to recover from his earlier trip to the canvas. However, Duarte regained enough control in the championship rounds to leave the arena victorious despite seemingly unanimous disapproval from the crowd.
