On the other side of the ring, a reserved Luis Ortiz looked to knock out and silence down his outspoken opponent. Ortiz himself began starting to push Wilder backwards as he himself started to land shots of substance onto the champion.
However, after turning the contest around, he retained the title when the referee stopped the fight in the 10th round after Wilder threw a barrage of punches.
Wilder, who had ended all but one of his previous 39 wins inside the distance, seemed to be sailing to another knockout win when he dropped Ortiz late in the fifth round.
It was all going Ortiz's way and he should have done more to get his opponent down before the 10th-round when he was knocked out by a brutal punch.
It turned out to bite Ortiz in the end, as he used up most of his tank trying to knockout Wilder.
Wilder drilled Ortiz with a right hand early in the seventh, but a resilient Ortiz cracked an over-anxious Wilder with a right hook that hurt Wilder badly. The challenger stalked him but was unable to pin him down for another set of attack.
Oritz (28-1, 24 KOs) look as if he was going to hand wilder his first loss in the 7th round, when he landed a strong counter right that stunned the champ, which he followed with a barrage of punches.
Stats show that in a combined 67 fights (not counting the NC's for Ortiz), only four times was the final bell chimed. I always said that I wanted to unify.

Lou DiBella, Wilder's promoter, praised his guy after the fight, but may also have predicted a certain future. "He put up a great fight, he was a great contender and my heart goes out to him". "We knew we had to wear him down", Wilder said.
It was not a classic, the crowd booed at points, Wilder missed with insane shots and Ortiz, comfortably in front, shuffled out for round 10 like a man clanking his way to the electric chair; he was just nine minutes from the glory land when he tumbled over for the first of three visits to the canvas in the tenth. A lot of people have been avoiding him even champions that are champions to this day have avoided Luis Ortiz. Joshua and Wilder would both be correctly favored over any other heavyweight in the division now, but is it a risk the stakeholders want to continually take while fans are craving this heavyweight superfight, especially given the vulnerability both men have shown recently?
