Canelo Alvarez defeated Rocky Fielding with a third-round TKO to take the WBA world super-middleweight title in his  Madison Square Garden debut on Saturday. With an onslaught focused almost exclusively on the body, Alvarez scored four knockdowns in all — all four on left hooks downstairs — to the delight of a pro-Mexican sellout crowd of 20,112.

Despite a five-inch advantage in both reach and height, Fielding (27-2, 15 KOs) lacked both the power and speed to land anything of consequence on Alvarez (51-1-2, 35 KOs), who connected to the body on 35 of his 73 total shots landed, according to CompuBox.

It marks the first fight in an 11-match, $365 million deal that Canelo inked with the DAZN streaming app. Alvarez, alongside IBF-WBA heavyweight champ, Anthony Joshua, is a part of an overarching strategy from DAZN to become the premier boxing broadcaster in the United States, hopefully parlaying into other sports along the way. DAZN was the big winner on Saturday night, especially with HBO out of the boxing game.

Alvarez was coming off the biggest win of his career in September, when he narrowly outpointed Gennady Golovkin to win the unified middleweight world championship in the biggest fight of the year, a rematch of last year’s controversial draw. Alvarez got back in the ring and showed the world why he is one of the best in the sport today.

Only eight other Mexican fighters have held three division titles. And Alvarez, 28, says he is headed back to the 160-pound class he rules, with possibly a third go with Golovkin in 2019. The next fight, opponent unknown, is set for Las Vegas in early May.
