Tim Tszyu got rid of Carlos Ocampo even faster than Errol Spence Jr. stopped him five years ago.

Tszyu dropped the Mexican contender twice and beat him by first-round knockout in their 12-round, 154-pound title fight Sunday afternoon at Gold Coast Convention & Exhibition Centre in Broadbeach, Australia. Tszyu impressively retained the WBO interim junior middleweight title he won when he beat Tony Harrison by ninth-round TKO three months ago in Sydney.

The Sydney native also maintained his position as the WBO’s mandatory challenger for undisputed 154-pound champion Jermell Charlo. Tszyu (23-0, 17 KOs) expects that his fight against Charlo (35-1-1, 19 KOs) will be rescheduled for later this year, perhaps as early as an undetermined date in October.

“I got a question for everyone here,” Tszyu told Ben Damon in the ring during his post-fight interview. “What’s my motherf****** name?”

The 27-year-old Ocampo (35-3, 23 KOs) lost in the first round for the second time in his career. Spence (28-0, 22 KOs) stopped him at the very end of the first round of their fight for Spence’s IBF welterweight title in June 2018 at the Dallas Cowboys’ practice facility, Ford Center at The Star, in Frisco Texas.

“I think Errol did it in what, 2½ minutes, just near the three-minute mark,” Tszyu said. “I think I got him out of there a bit earlier, so I beat you, Errol. I beat you to it.”

Tszyu, 28, also beat Ocampo just three weeks after a dog bit him on his right arm at a friend’s barbeque. The gash required surgery and 26 stitches to close the wound, but Tszyu returned to training only two days later.

The injury obviously didn’t impact his performance against Ocampo.

Tszyu blasted Ocampo with a left-right combination barely 20 seconds into their fight and never allowed the staggered challenger to recover. Tszyu continued to crush Ocampo with power punches until he drilled Ocampo with a right hand that sent him to his gloves and knees exactly a minute into the first round.

An overwhelmed Ocampo got up at the count of five, but he didn’t last much longer.

Tszyu blasted Ocampo with a left hook that knocked him down again with 1:35 to go in the first round. Referee Danrex Tapdasan immediately stopped their fight once Ocampo went down the second time.

Ocampo went 12 rounds with former WBC interim super welterweight champ Sebastian Fundora two bouts before Tszyu blew him out. Fundora (20-1-1, 13 KOs) was unbeaten when he defeated Ocampo by unanimous decision October 8 at Dignity Health Sports Park in Carson, California.

The big underdog showed no such resistance against Tszyu, who delighted another sellout crowd in his home country. Though thoroughly satisfied with his quick victory, the son of legendary former junior welterweight champ Kostya Tszyu quickly turned his attention to Charlo.

“The big one’s coming up, so that’s where I’m going,” Tszyu said in reference to the United States. “That’s where I’m heading. I’ve got this interim belt, but I’m not satisfied. I want all four. And it’s not just the belts. I literally just want the name Charlo on my resume.”

Tszyu was scheduled to challenge Charlo for the Houston native’s IBF, WBA, WBC and WBO belts January 28 at Mandalay Bay Resort and Casino’s Michelob ULTRA Arena in Las Vegas. Their fight was postponed indefinitely after Charlo suffered two fractures in his left hand during a sparring session a few days before Christmas.

Instead of simply waiting for their fight to be rescheduled, Tszyu insisted on remaining very active against Detroit’s Harrison (29-4-1, 21 KOs), the only opponent to beat Charlo, and Ocampo.

“I did it quicker than your boy, man,” Tszyu said to Charlo in reference to Spence, who, like Charlo, is trained by Derrick James. “So, come on, get your hand healing. Let’s dance. Let’s dance in October. No disrespect – let’s just dance. Me and you, best dancing partners we’ll be.”
