Undefeated Australian superstar Tim Tszyu blitzed contender Carlos Ocampo with a stunning, first-round knockout on Saturday to defend his interim-WBO junior middleweight title, as he headlined a packed event from the Gold Coast Convention and Exhibition Centre in Broadbeach, Queensland, Australia.

Tszyu (23-0, 17 KOs) dropped Ocampo with a right hand barely a minute into the fight and finished him with a lunging left hook that propelled Ocampo (34-3, 22 KOs) down and into the ropes, causing referee Danrex Tapdasan to stop the bout at 1:17 of the first round. Tszyu – whose father Kostya was a former undisputed world champion – immediately set his sights on the undisputed 154-pound kingpin Jermell Charlo, who withdrew from their scheduled fight in January with a broken left hand.

Tszyu went through with the bout on Saturday despite undergoing surgery less than three weeks ago after a dog bit his right forearm, leaving an ugly, silver-dollar size gash. It only seemed to galvanize him.  

The fight with Charlo is going to take place in the United States, likely in Las Vegas, with the WBO ordering the fight to take place by the end of September.

“I have a question for everyone here, what’s my mother— name?” Tszyu said in the ring after securing his second win in three months in Australia.

“I think that was a statement. There’s no battle with America. That’s the land I want to conquer. That’s where the big one is coming next. I want Charlo on my resume. So, get it in here and let’s dance in October. I’ve overcome a lot of adversity, so it was about pushing through. I didn’t think it would be this quick. I feel like a pit bull and there’s no stopping me. The big one is Charlo so get your tickets. We’re coming back with four belts.”
