New York (AFP) - Undefeated champ Deontay Wilder destroyed Bermane Stiverne by knocking out the out-of-shape challenger with one second left in the opening round to retain his WBC (World Boxing Council) heavyweight championship on Saturday (Nov 5).

The 32-year-old Wilder delivered an explosive performance as he floored Stiverne two times in the opening round before finishing him off with a punishing right-left combination to the head as the defenceless Canadian was pinned against the ropes.

Stiverne then slumped to the canvas and stayed motionless for some time before being helped up into a chair where he was examined by the ring doctor at the Barclays Centre arena in New York.

"I know I am the best. I just want to prove that I am the best," said Wilder, who has 39 wins and 38 knockouts. "I got the heart of a lion. I am the king."

Wilder was the heavy favourite going into the sixth defence of his heavyweight title.

It was his second win over the 39-year-old former champion Stiverne, who came into the rematch 15 pounds (6.8kg) heavier and having fought just once since losing the belt to Wilder in January 2015.

He won the first fight with a one-sided unanimous victory and the rematch was even easier.

Wilder flattened Stiverne with 45sec left in the first round with a left hook followed by a straight right that landed flush on the face of the Haitian-born challenger.

Just 20sec later, he sent Stiverne back to the canvas with a heavy right hand that landed like a club to the side of the head.

By this time, Wilder was having his way with Stiverne as he sealed the victory with a four-punch combination that sent Stiverne awkwardly back into the ropes as referee Arthur Mercante frantically tried to intervene and stop the onslaught.

The Canadian earned another crack at Wilder in September, taking the rematch on short notice after the scheduled challenger, Cuban Luis Ortiz, failed a doping test.

"So much frustration. Man... It just seems like my career has been crazy. So many guys ducking me and so many guys using PEDs (performance-enhancing drugs)," said Wilder.

Wilder was so confident that he would win again that he vowed to retire if he lost.

Stiverne blamed health issues for his failure to muster much resistance to Wilder's onslaught in their first meeting, but the beefy boxer's biggest mistake the second time around appeared to be spending too much time around the buffet table.

Still Wilder said he respected Stiverne's willingness to accept the challenge.

"It took lot of courage to step in ring with someone like me. He was a clean fighter and he did the best he could," Wilder said.

Wilder hopes this win will land him a super fight with Anthony Joshua in a heavyweight showdown that the boxing world is dying to see.

He issued a call for British star Joshua, who is the IBF (International Boxing Federation) and WBA (World Boxing Association) heavyweight champ, to step up to the plate.

"I been waiting on that boy for a long time now. Listen mate. I know I am the best. Are (you) up for the test? I want Joshua. Joshua come and see me baby," Wilder said.

On the undercard, Kazakhstan's Sergey Lipinets claimed the vacant IBF junior welterweight title with a unanimous decision victory over Akihiro Kondo of Japan.

Lipinets improved to 13-0 with 10 KOs as he won on all three judges' scorecards, 118-110, 117-111 and 117-111.

Kondo, the third-ranked challenger with a career record of 29-6-1 coming into the bout, was fighting for his first world title in his debut fight on American soil.
