Saul "Canelo" Alvarez re-unified the IBF super middleweight championship with his WBA (Super), WBC and WBO belts with a unanimous decision victory over William Scull on Sunday, setting up a bout with former welterweight champion Terence Crawford in September.

Canelo Alvarez has beaten William Scull in a unanimous points decision to become undisputed super middleweight champion again.

Canelo Alvarez won the decision. William Scull acted indignant. But the real winner after 12 stupefyingly dull rounds between the two guys holding claims to elite status at 168 pounds was neither the Mexican superstar nor the Cuban runner. It was Terence Crawford, presuming he stayed awake at ringside.
