Tszyu entered the ring after having had surgery three weeks ago on his right arm after a dog bite, but any chances of that affecting his prospects soon disappeared.
The Australian started at a fast pace, landing combinations at will. Some huge right hands followed, with a left hook that sent Ocampo to the floor.
And the rest was history, as the fight lasted 72 seconds. In doing so, Tszyu landed 14 combinations as his opponent failed to last one.
As a result, Tszyu kept his record to 23-0 with 17 knockouts to stay as mandatory to Jermell Charlo.
“I think it was a statement made. America is the land I want to conquer, the land I’m going to next, the big one is coming. I’ve got the interim belt, but I’m not satisfied.
“I want all four. I want the name Charlo on my resume. I’ve copped a lot of adversity coming into this fight and it was just about pushing through. I didn’t think it would be that early, this guy is a warrior,” Tszyu
