Canelo Alvarez won back the WBC super-middleweight title on Saturday, beating Christian Mbilli by unanimous decision in Riyadh, Sky Sports and Sporting News reported.

The judges scored the fight 115-112, 116-111 and 117-110 for Alvarez, the two outlets reported. Alvarez lost the title to Terence Crawford about a year ago, Sky Sports said. He is 36, Sporting News reported.

Mbilli had a point taken away for hitting Alvarez on the back of the head, the two outlets reported. Sporting News said it came in the eighth round. Mbilli had been unbeaten before the fight, Sky Sports said.

"It's so difficult to explain. It's something unbelievable," Alvarez said after the fight, Sky Sports reported. He noted that he won his first title 16 years ago. He said he would take "a couple of weeks off" and then come back, the outlet said.

On the same card, Jaime Munguia beat Nikita Zon by unanimous decision to keep his WBA super-middleweight title, Sky Sports reported. Zon badly hurt Munguia in the sixth round, but Munguia took control late, Sky Sports said. Sporting News said the judges scored that fight 116-112, 117-111 and 117-111.

Rafael Espinoza kept his WBO featherweight title against Ricardo Blandon, Sky Sports reported. A ringside doctor stopped the fight in the third round after Blandon suffered a bad cut near his eye, the outlet said.

Alvarez had been out of the ring for more than a year, Sporting News reported. Mbilli pushed him early, but Alvarez took control from the sixth round on with sharp uppercuts and right hands, Sky Sports said.
