Deontay Wilder retained his WBC heavyweight title in impressive fashion, knocking Dominic Breazeale out in the first round on Saturday.
Wilder recorded the 40th knockout of his career just two minutes, 17 seconds into the fight at Barclays Center in New York.
Wilder (41-0-1) started well and capitalised, landing the decisive blow quickly against his mandatory challenger and fellow American.
After a war of words in the build-up, Wilder showed his class in his first fight since drawing with Tyson Fury in December, his performance set to again lead to calls for a rematch with the Brit or fight with fellow heavyweight champion Anthony Joshua.
Wilder made a fast start and he had Breazeale in trouble early after a big left hand, only for the latter to steady – albeit very briefly.
Just seconds later, the fight was over.
Wilder landed a left-handed jab before a huge right sent Breazeale to the canvas, ending the fight and marking a ninth successful title defence.
"I think the ref stopped it a little early because I could hear him saying seven and eight, but that's boxing," said Breazeale. "He did his job and kept us safe for our next fight.
"I got on my feet and had my legs under me. It's the heavyweight division so there's going to big shots from guys with power. This was a situation where he landed the big right hand before I did. I thought I was going to come on in the later rounds. I'll be back and go for the heavyweight title again."
