Stiverne lasted all of 179 seconds before referee Arthur Mercante stopped the fight.
The first knockdown came when Wilder landed perhaps the strongest one-two punching combination in the sport: a left jab, followed by a strong right, which broke through the defensive guard of Stiverne, dropping his overmatched opponent with 51 seconds remaining.
In the first fight between the two, where Wilder (39-0, 38 KOs) defeated Stiverne (25-3-1, 21 KOs) by unanimous decision in January 2015 to win the WBC World Heavyweight Title, which he currently holds, Stiverne was rocked on many occasions but never officially dropped.
The 6-foot-2 Stiverne, who weighed in at 255 pounds Friday morning, gingerly rose to his feet, got in his stance and stepped over to Wilder, who was staring down Stiverne.
The 6-foot-7 Wilder snapped out of his glare, landing a four-punch combo, the final of which was a thunderous overhand right. Though partially deflected, it still managed to floor Stiverne 24 seconds after the first knockdown.
After walking over to the neutral corner, engaging with those in attendance, Wilder eyed a lumbering Stiverne, and finished him off with one second to spare.
He left his opponent laying on the bottom rope using it as a head rest, while his knees were inverted and his legs bent backward as Wilder postured in victory.
Stiverne had massive trouble getting to his feet this time, but at this point, it didn’t matter.
“So much frustration,” said Wilder afterward regarding Alexander Povetkin, Andrzej Wawrzyk and, prior to Saturday, Luis Ortiz, top-flight heavyweights who failed drug tests after scheduling bouts with Wilder. “It’s been crazy so many guys using PED’s. I just want to prove that I am the best. I know I am the best, but I wanna prove I am the best.”
That leaves one option: Anthony Joshua.
Joshua, (20-0, 20 KOs), is the uber-popular (in his home of the United Kingdom) 6-foot-7, 250-plus pound IBF, WBA Super and IBO World Champion, who stopped long-time heavyweight kingpin Wladimir Klitschko in April and Carlos Takam on October 28.
Wilder has been saying Joshua’s name for months, but Joshua’s promoter, Eddie Hearn of Matchroom Boxing, hasn’t reciprocated similar energy. Wilder and his Brooklyn-based promoter, Lou DiBella of DiBella Entertainment, have noticed.
“I’ve been waiting on that fight for a long time now, I declare war upon you,” Wilder directed at Joshua and his camp. “Do you accept my challenge? I’ve been waiting for a long time. I know I’m the champion, I know I’m the best, are you up for the test?”
“Why can’t it happen next?” DiBella added at the post-fight press conference. “They literally fought one week apart, neither one of them is hurt and they’re exactly on the same schedule. Anthony Joshua doesn’t want to fight this man. Eddie Hearn doesn’t want Anthony Joshua to fight this man.”
Hearn had previously mentioned a potential fight between Wilder and the UK’s Dillian Whyte (22-1, 16 KOs), which Wilder’s camp tried to make happen after Joshua opted for another opponent, but Hearn subsequently went silent.
Wilder was asked about Whyte, whose only defeat was to Joshua in December 2015 and who earned a controversial, underwhelming decision win over journeyman Brit Derek Chisora in December 2016.
His response regarding the UK challenger?
“A king doesn’t chase peasants, a king takes kings. I want Joshua,” he said. “Why should I go to England to fight a peasant without the king on the contract? The world wants Joshua. The world wants Wilder. No more dodging, no more excuses, make the date, don’t wait.”
