Deontay Wilder did exactly what he promised to and smashed Bermane Stiverne in their WBC heavyweight world title rematch at the Barclays Center, Brooklyn.
It was a second before the final bell for the first round when Stiverne was done.
Wilder seemed super confident and as if overlooking Stiverne before the fight, but turned up for the night and knocked him down twice, before finally unleashing a cannonade and ending the bout.
This is the sixth successive defense of the WBC belt for Wilder and he is more eager than ever for a unification mega fight with Anthony Joshua.
Wilder began the fight with caution, working on the jab and keeping the distance. He then opened up his guard as if inviting Stiverne to attack and it was 50 seconds before the end of first round when a left-right combination sent the challenger to the ground.
"The Bronze Bomber" gained confidence and stood right in front of Stiverne, demonstrating his superiority. Another four-punch combination sent "B.Ware" to the canvas again and he was looking done and dusted.
Stiverne was close to being saved by the bell, but Wilder released the bombs and ended everything for the 39-year old with just a second left.
This was Stiverne`s first fight in two years, and although he promised a different result than in their first bout, he failed to deliver. Deontay, on the other hand, impressed and seems to have won in a situation where he had much to lose and a little to gain.
Watch: Wilder's KO
Speaking after the knockout victory, Wilder once again turned to WBA (Super), IBF, and IBO heavyweight champion Anthony Joshua.
"I had so much frustration, my career has been crazy, I just want to prove that I am the best, I know it, I just want to prove it," he said, per Sky Sports.
"I am too athletic, I am mobile, I am hostile, I have the heart of a lion. I am the king, baby."
"No heavyweight can compare to me, I move like a middleweight, man. The things I can do in the ring is crazy, the way I set these guys up... I' m very confident in what I do."
Wilder showed love and respect for Stiverne, who took the fight, did his best and unlike some of his previous opponents, did not test positive for banned substances.
However, he played down an eventual bout with Dillian Whyte, claiming: "A king don`t chase the peasants, king chase kings! I want Joshua!
"The world want Joshua. The world want Wilder. I want Joshua! Joshua, come and see me baby!
"No more hiding, no more ducking, no more dodging, no more excuses, let`s make the fight happen!"
Wilder explained he is willing to go and fight anywhere, because he is a World champion and wants to prove he is the best.
"Let`s see who is the best, I know I'm the best, are you up for the test?"
