Diego Pacheco successfully defended his WBC Silver and WBO International super middleweight titles on Saturday night, stopping veteran Immanuwel Aleem in the 11th round of the main event at Dignity Health Sports Park in Carson, California.

Pacheco controlled the fight from the opening bell, using his jab and body attack to dictate the pace while gradually wearing Aleem down. After building a comfortable lead through the middle rounds, the unbeaten contender finally broke through in the 11th, trapping Aleem against the ropes and unloading a barrage of punches that forced referee Ray Corona to stop the contest.

The victory improves Pacheco to 26-0 (19 KOs), while Aleem falls to 22-5-3 (14 KOs).
