Oscar Collazo Dominates Jesus Haro to Retain Unified Strawweight Championship

Oscar Collazo demonstrated exactly why he reigns as the undisputed king of the strawweight division, delivering a masterful beatdown that forced Jesus Haro to quit on his stool after six punishing rounds at the Honda Center in Anaheim, California.

The Puerto Rican southpaw retained his WBA and WBO unified strawweight championship in dominant fashion, improving his perfect record to 14-0 with 11 knockouts in a Golden Boy Promotions co-main event that showcased the vast gulf between champion and challenger.

Collazo entered the bout expecting minimal resistance from Haro, who carried a modest 13-3 record and had suffered two defeats in his previous four contests. The champion proved prophetic in his assessment, controlling every aspect of the fight from the opening bell.

I knew he was going to come just to survive, Collazo revealed post-fight, demonstrating the tactical awareness that has made him such a dominant force at 105 pounds.

The 23-year-old Californian Haro employed a defensive strategy from the outset, moving constantly around the perimeter of the ring in hopes of frustrating the champion and avoiding serious damage. However, Collazo refused to be denied, fighting with relentless pace while maintaining exceptional defensive discipline.

The champions game plan centered on systematic body work that gradually wore down his opponent. Collazo mixed sharp jabs with devastating left hooks to the ribs, creating a punishing rhythm that slowly sapped Haros will to continue.

I landed hard body shots in the fourth and fifth, roughing him up, and I looked at his corner, Collazo explained. And he was breathing heavily. So I put on the gas pedal, and went for him.

Once Collazo identified his opponents vulnerability, the fight became a methodical dismantling. From the fifth round forward, the champion stalked Haro around the ring, cutting off escape routes and landing troubling shots at mid-range.

When Haro attempted to tie up his tormentor and buy respite from the punishment, Collazo continued throwing punches, refusing to allow any pause in the action. The relentless pressure and accumulating body damage gradually broke down the challengers resistance.

The end came not with a dramatic knockdown, but with a defeated fighter telling his corner in Spanish, I dont want any more of this. Haro remained on his stool between rounds six and seven, unable to answer the bell as referee Thomas Taylor called the victory a knockout.

Collazo celebrated atop his coaches shoulders while the Puerto Rican flag waved proudly in the background, a fitting image for a fighter who has established complete dominance in his weight class.

The body shots were having an effect on him in the fifth round, Collazo analyzed. I knew sooner or later that Id get the stoppage if I stayed calm, used the jab, kept using body shots and just made him move to stress him out entirely.

With his latest defense complete, Collazo immediately called for a rematch against WBC champion Melvin Jerusalem, whom he stopped in the seventh round during 2023. The Puerto Rican star wants to face the Filipino fighter again, should Jerusalem emerge victorious in his upcoming May 18 bout.

Im the king of the 105-pound champions, Collazo declared confidently. Ill fight anybody. Melvin, I hope you win May 18. Im coming for you.

The champion concluded by expressing ambitious goals for the remainder of 2026, stating his intention to scale up the pound-for-pound rankings and enter the top five by years end.
