33. Luis Ortiz
Ortiz doesn’t enjoy the profile of the likes of Deontay Wilder or Anthony Joshua. But most boxing fans identify him as one of the sport’s boogeymen. The Cuban is one of the best heavyweights in the world and remains an elite talent in his forties. ‘King Kong’ has fought the best of the best throughout his career. His only defeats came against Wilder and he was winning their second fight handily before the latter knocked him out.

An Olympic silver medalist, Ortiz endured many questions surrounding his age throughout his career. Many analysts believed that he was older than his birth certificate states, even though there is nothing to justify this. However, there is no doubt that Ortiz is one of the best older boxers in the world. It’s remarkable that he can fight so well at his age against much younger men.
