Canelo Alvarez entered the ring for Saturday's return in San Antonio already bearing the label as the sport's pound-for-pound king. He left with a pair of super middleweight world titles and a warning to anyone else wearing a belt when he said, "We are coming for more." Alvarez won a major world title in his fourth division by thoroughly outclassing Callum Smith inside the Alamodome in a unanimous decision (119-109 twice, 117-111). The Mexican superstar, who entered with the secondary WBA title, captured Smith's full WBA belt and the vacant WBC championship.
