Canelo Alvarez beat William Scull in a unanimous points decision on Saturday night to become undisputed super middleweight champion again.

The 34-year-old Alvarez is a four-weight world champion and entered the fight with the WBA, WBC and WBO titles at 168 pounds.

He was stripped of the IBF belt last July when he declined to make a mandatory defense against Scull.

Alvarez became a two-time undisputed champion in the division for the second time when the judges scored it 115-113, 116-112, 119-109.

British heavyweight Anthony Joshua watched on from ringside in Riyadh after revealing he will not return to the gym until July because he needs elbow surgery.

Canelo’s fight against IBF champion Scull didn´t live up to the hype. Moments after the decision was declared, the promotion for his September 12 fight against Terence Crawford began.

Alvarez was fighting outside the U.S. or Mexico for the first time and had to make plenty of adjustments, including adjusting to the time zone.

The fighters walked into the ring and the anthems started around 6:20am local time in Riyadh, timed so it was in prime time on America’s West Coast.

The opening rounds were slow with both boxers feeling for range and the intensity gradually lifted with Scull throwing many more punches but barely landing any.

Alvarez, by contrast, stayed patient and was landing powerful body punches.

Scull kept moving around, dodging and shuffling, frustrating Alvarez, who later said he hated fighting that style of boxer.
