Dmitry Bivol won in a unanimous decision over Canelo Alvarez to retain his WBA light heavyweight title in Las Vegas on Saturday.

Using his height and longer reach to his advantage, the Kyrgyz-born Russian landed the cleaner and harder shots against Alvarez in a clinical display.

All three judges handed down scores of 115-113 in Bivol's favour despite what was largely a non-competitive fight.

Alvarez confirmed he would exercise his rematch clause and Bivol took no issue, believing the win solidifies his status in the division.

"No problem," Bivol said via translator post-fight. "I took this fight because I just wanted to get the opportunity and I appreciate this opportunity.

"I didn't fight for anything except getting the fight.

"I'm ready for the rematch, I just want to make sure that I can be treated like the champion now."

Bivol moved to 20-0 with his ninth consecutive title defence, while it marks the second official defeat of Alvarez's career in his return to light heavyweight following 2013's majority-decision loss to Floyd Mayweather.
