Gennady Golovkin retained his WBA super, WBC and IBO world titles against the short notice replacement, Vanes Martirosyan, at the Stubhub Center in Los Angeles.

The challenger was no match to the middleweight kingpin as ‘Triple G’ dominated the fight from start to finish and stopped Martirosyan in the second round.

Golovkin ties Bernard Hopkins with 20 title defences with his latest win. The longest-reigning active world champion in boxing said he was happy to get another KO on his belt after going to the distance twice against Canelo Alvarez and Danny Jacobs.

“It feels great to get a knockout,” said Golovkin after the fight.

“Vanes is a very good fighter. He caught me a few times in the first round. In the second round, I came out all business after I felt him out in the first round.”

‘GGG’ improved his record to 38-0 with 34 wins coming via stoppage
