Deontay Wilder was in an explosive mood during his fight against WBC Mandatory challenger, Dominic Breazeale, as he breezed past him in the first round at the Barclays Center in Brooklyn on Saturday.
There was tension between both Americans before the fight following their face off in which Breazeale said all the right things to the fury of the WBC champion.
A heavy right hand ultimately made all the bad blood shared between them a moot point when he knocked him down after 2 minutes,17 seconds of Round 1.
The 33-year-old who is undefeated after 41 career fights of which he has won 40 by knockout defended his WBC title which he originally won in 2015 for the ninth time.
Wilder was heavily criticized for comments he made before the fights when he threatened Breazeale's life inside the ring and shared his hope to one day add a dead body to his record.
"Everything just came out of me tonight. I know there was a lot of words and animosity against each other and it just came out tonight. This is what makes boxing so great when you can have so much inside and just overcome," Wilder said after his win.
"I think the ref stopped it a little early because I could hear him saying seven and eight, but that's boxing," Breazeale said after he recovered from the punch.
"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 [Wilder] 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."
