Abner Mares attacked relentlessly on the way to a unanimous decision over Anselmo Moreno on Saturday night, defending his WBC 122-pound title and handing Moreno his first defeat in a decade.
Leo Santa Cruz also defended his IBF bantamweight title, stopping Victor Zaleta in the ninth round of a brutal fight on a thoroughly entertaining card at Staples Center.
Alfredo Angulo stopped Raul Casarez with a single left hook 56 seconds into the first round, making a dramatic return to the ring after a year away. Earlier, Welsh light heavyweight Nathan Cleverly defended his WBO title with an eighth-round stoppage of Shawn Hawk.
Mares (25-0-1) rarely stopped moving forward in a fascinating brawl with Moreno (33-2-1), the elusive Panamanian star. In the fifth round, Mares scored the first career knockdown of Moreno, who had won 27 straight fights since October 2002.
