That said, Stiverne was the first and only man to take "The Bronze Bomber" the distance, but in their rematch last November, it was a completely different story.
After putting Ortiz down in the fifth round, Wilder was on the receiving end of a barrage of punches at the end of the seventh, and was lucky to survive to the bell. We each put on a great performance and I think the fans were happy they were here. "I am the baddest man on the planet and I proved that tonight. this solidified my position at the top of the food chain tonight".
Ortiz would make it up at the count of nine but was clearly out on his feet. The fight will be held at the Barclays Center, in Brooklyn, and televised by Showtime, and it is created to be a showcase for Wilder. Not only are both titleholders unsafe when hurt, but both have the heart to be especially risky in the following rounds, making it increasingly hard to count either man out.
"I am looking forward to Cardiff, I have never been there. I am ready whenever those guys are", he added in the post-fight press conference via Boxing Scene. "He sees that as an easier fight potentially than the Joseph Parker fight", Hearn told Sky Sports UK.
"A true champion always finds a way to come back and that's what I did tonight".
His technique is often found to be wanting, but he always seems to have that destructive power as a get out clause.
This fight is unlikely to go the distance. Ortiz was tough, stood his ground, and did a good job of neutralizing Wilder's thudding jab. Ortiz returned, kept winning, and agreed a year ago to face Wilder.
WBC champion Wilder squares off against Cuban Luis Ortiz in NY on Sunday (NZ time) and if the 32-year-old wins, he will face off against the victor of Parker and Joshua later in the year.
Wilder now wants Anthony Joshua, he wants about 10 million dollars more than he got on Saturday night and he appears to want just about every advantage for a fight that is hopefully inevitable. I had to earn this win. Don't ask me tomorrow, though, as I could have a different answer.
Kell Brook won the vacant silver super welterweight tile with a two-round bashing of Siarhei Rabchanka. The bout will again take place at the 168 pound super middleweight limit. After all, both are linked to Al Haymon, the powerful boxing entrepreneur behind a series called Premier Boxing Champions; this gives them extra incentive to work together. "We'll get this AJ fight, we'll make you some real money".
The 32-year-old gathered all his experience to regroup in the next couple of rounds before doing what he does the best - unleashing wild swings and having his opponent on knees. I thought I was winning the fight.
