Puerto Rico's Oscar 'El Pupilo' Collazo successfully defended his WBA Super World Championship in the minimumweight division with a dominant victory over challenger Jesús 'Chiquito' Haro on Saturday night at the Honda Center in Anaheim, California. Collazo forced Haro's corner to throw in the towel before the start of the seventh round, sealing a retirement victory (RTD) after a display of relentless, systematic punishment.

Why it matters

Collazo's victory further cements his status as one of boxing's premier pound-for-pound talents and the undisputed king of the 105-pound division. The win sets up a potential summer showdown between Collazo and Filipino standout Melvin Jerusalem to determine the undisputed ruler of the minimumweight class.

The details

From the opening bell, Collazo imposed a suffocating pace that the young Nevada challenger Haro simply could not contain. Collazo's blueprint was clear: break Haro down with a sustained body attack. Thudding hooks to the liver and digging shots to the solar plexus steadily eroded the challenger's mobility. Although Haro showed grit and attempted to fire back in the early frames, he was ultimately overwhelmed by the champion's power and sheer punch output. The gap widened in the fifth and sixth rounds, when Collazo 'stepped on the gas,' unleashing sharp combinations that left the challenger visibly hurt and without effective defensive answers.
