AGUASCALIENTES, Mexico — Antonio Margarito won a unanimous decision over Roberto Garcia on Saturday in his first fight in more than 15 months following a one-year suspension.

Margarito outclassed Garcia, who absorbed most of the punishment and was knocked down in the first round of the 10-round bout by a right-left-right combination.

Margarito, who weighed in at 154 pounds, improved to 38-6 with 27 KOs. Garcia fell to 28-3 with 21 KOs. Margarito, a former welterweight champion, was suspended a year after being caught with illegal hand wraps in a loss on Jan, 24, 2009, against Shane Mosley.

Margarito, 32, was a winner on all three judges' cards: 99-89, 100-88 and 99-90.

He used his longer arms to fend off the 30-year-old Garcia, who lacked the quickness needed to overcome his opponent's reach advantage and boxing savvy.

Margarito claimed he knew nothing about the illegal wraps and blamed his trainer Javier Capetillo, whom he fired.
