Canelo Alvarez vs. Gennady Golovkin 2 Results: Alvarez Tops GGG, Analysis, Highlights, Scorecard

Get a round-by-round reaction to the rematch of Gennady Golovkin and Canelo Alvarez's middleweight title bout.

Gennady Golovkin defended his unified world middleweight title against Canelo Alvarez Saturday at T-Mobile Arena in Las Vegas.

The bout was a rematch of a fight that took place this time last year and ended in a controversial draw. Since meeting back in 2017, the fighters have taken very different paths to get to this match.

Golovkin defended his title against Vanes Martirosyan on May 5 and earned a second-round knockout to improve his record to 38-0-1.

Alvarez had been at the center of controversy thanks to a pair of failed drug tests. He claimed it was tainted meat from his native Mexico that caused his samples to come back positive for clenbuterol, but Alvarez was still given a six-month suspension by the Nevada State Athletic Commission.

That suspension prevented the two from having their rematch on May 5, thus leading to Golovkin facing Martirosyan.

Saturday's long-awaited rematch was the final fight on a card that featured three knockouts. Roman Gonzalez knocked out Moises Fuentes in the fifth round, David Lemieux knocked out Gary O'Sullivan in the first round and Jaime Munguia knocked out Brandon Cook in the third round.
