Julio Cesar Chavez Jr. retained his WBC round unanimous decision over Marco Antonio Rubio Saturday night at the Alamodome.

With his father, Mexico boxing legend Julio Cesar Chavez ringside, the younger Chavez (45-0-1 31 KOs) took control of this bout early and pounded away with body shots in the middle rounds. Rubio (53-6-1, 46 KOs) threw 402 more punches than Chavez, but landed 36 less than the champion.

That led the judges to score the bout 118-110, 116-112, and 115-113 in favor of Chavez, who was successful in his second title defense. He won the crown over Sebastian Zbik lase June and then scored a fifth-round TKO of Peter Manfredo Jr. in November.

In round 11 on Saturday, Rubio landed a right uppercut in the first minute, but couldn't gain momentum. The fighters went toe-to-toe later in the round before Chavez went on the offensive, a familiar story in the fight.
