Brandon Rios knocked out Miguel Acosta in the 10th round with a flurry of punches near the corner to win the WBA lightweight title on Saturday night. Rios landed several blows without seeing any defense before finally crumpling Acosta with a right cross at 1:14 of the tenth round. The Venezuelan's corner men immediately reached through the ropes to support him as referee Joe Cortez stopped the fight.
