LAS VEGAS – Saul “Canelo” Alvarez retained his undisputed super-middleweight world title with a convincing unanimous decision over fellow Mexican Jaime Munguia on May 4.

Alvarez handed Munguia the first defeat in 44 professional bouts, dropping the 27-year-old challenger in the fourth round and inexorably taking control to improve to 61-2-2 in his storied career.
