(video by Ryan Burton) - WBA welterweight champion Yordenis Ugas was ringside at MGM Grand in Las Vegas, and watched Saul "Canelo" Alvarez (57-1-2, 39 KOs) become the undisputed champion at 168-pounds with a sensational knockout of unbeaten Caleb Plant (21-1, 12 KOs) in the eleventh round.

Canelo unifies the entire super middleweight division in a year's time. He captured the WBC, WBA titles back in December with a dominating decision win over Callum Smith. He then added the WBO titles back in May, when he stopped Billy Joe Saunders in eight rounds after fracturing his orbital bone.
