The Cuban veteran lost in ten rounds to Wilder in the American’s title defense last March in what was seen as a career-best victory for the Tuscaloosa puncher.
Ahead of his return to action this weekend, Ortiz waded in on the debate raging since Joshua decided against a unification with Wilder in 2018.
“Wilder would knock out Joshua in three rounds,” said Ortiz, in an interview with Lem Satterfield of Premier Boxing Champions. “Wilder’s the faster and more aggressive of the two fighters. Of the two fighters, Wilder probably has the better chin. Joshua will not be able to withstand Wilder’s punching power.
“Wladimir Klitschko put Joshua on his (a**), and a younger Wladimir would have gotten him outta there,” he continued.
“Wilder will not forget what Klitschko did to Joshua, so I see Wilder being all over him and Joshua hitting the floor.
“Joshua will have no answer for Wilder’s style, which is a crazy powerful approach coupled with his chin.
“With all of that being said, Wilder is the superior fighter. Joshua will not be able to withstand his punches at all, point-blank, period,” concluded to former number one contender.
Joshua faces Alexander Povetkin on September 22 at Wembley Stadium, whilst Wilder is yet to confirm his next move.
A clash has been touted to take place on April 13 in the UK, although still has a long way to go to get over the line.
For Ortiz, a comeback fight against Razvan Cojanu is on the horizon as part of Mikey Garcia’s unification encounter with Robert Easter on Saturday night.
