Canelo Alvarez defeated Rocky Fielding and is now a 3-division titlist

Canelo Alvarez kicked off the richest athlete contract in sports by doing just what was expected on Saturday night at sold-out Madison Square Garden.

Heavy favorite Alvarez, the unified middleweight world champion and boxing's biggest star, moved up one weight class and destroyed the game Rocky Fielding with a heavy body attack to take his secondary super middleweight world title by third-round knockout in his first non-pay-per-view fight since 2015.

Alvarez knocked Fielding down four times, much to the delight of the raucous pro-Canelo crowd of 20,112.
