In a tightly contested main event, Isaac Zarate (14-3-3, 2 KOs) pulled away in the second half against the very mobile Christian Ayala (12-2, 4 KOs) to win by unanimous decision (78-74, 77-75 twice) on Friday night.
Zarate, a southpaw from San Pedro, Calif., had trouble finding his range in the early rounds. Ayala smartly countered Zarate and kept him off balance. By the fourth round, however, Zarate discovered his jab and mixed in uppercuts to pull the tide in his favor.
