Gennady Golovkin made short work of late notice replacement Vanes Martirosyan, who replaced Canelo Alvarez after Canelo’s drug test failure for clenbuterol. Martirosyan was predictably a heavy underdog, seeing as he hadn’t fought for two years, and while he was a contender at junior middleweight, he’d never fought at middleweight before.

Martirosyan entered Saturday night at the StubHub Center in Southern California having never been knocked out. “GGG” changed that in a flash, as a vicious combination of punches planted Martirosyan face-first on the canvas and he failed to beat the count. A second-round KO for Golovkin (38-0-1, 34 KOs), as Martirosyan (36-4-1, 21 KOs) Another Edmond Tarverdyan trained fighter winds up on the wrong end of a highlight reel.

Here’s Bad Left Hook’s play-by-play of the ending:

Round 2: Right hand from GGG, and then a good uppercut hurts Vanes! Vanes ties up. That could’ve been a knockdown call, but Jack Reiss probably rightly rules it a push. GGG shoots another uppercut, it misses. Right hand from Vanes, hard left back from GGG! Right hand from GGG! Another! GGG opening up and Vanes is down, face-first to the canvas! The count is on! He’s on his knees at eight, but he’s counted out! Golovkin KO-2

Golovkin is still the WBC, WBA, and IBF middleweight champion, although it should be noted that the IBF did not sanction this as a title fight.
