CANELO ALVAREZ cemented himself as a fully-fledged four-division champion after dominating Britain's brave and resilient Callum Smith.
The Mexican superstar walked away with the WBA super-middleweight crown, two years after winning their secondary 'Regular' title.
Canelo had too much power and precision for Smith and stormed to victory after 12 one-sided and almost identical rounds in Texas.
After the win, he said: “I did a great job after 13 months out.
“Smith is a great fighter but I did a great job. I am so happy.
“I am the best in the world and from the first round I wanted to see what he brings but I showed what I am."
The first round started as a cagey affair, with Canelo coming forward and Smith happy to back himself up.
But it was not long until Alvarez asserted himself as the dominant force in the fight, landing jabs and body shots on his taller opponent.
From rounds two to four, Canelo walked forward, rocking Smith's head back, landing big right hands as the Brit covered up on the ropes.
The champion fortunately had a tight defence, but looked too tentative as he allowed the pound-for-pound king, 30, to outwork him.
