Rising Aussie boxing star Tim Tszyu has continued his undefeated ways by absolutely chopping down Jack Brubaker with his corner throwing in the towel in the fourth round.

Tszyu – the son of Aussie boxing great Kostya Tszyu – was dominant from the outset and in the third round he turned up the heat and once the bell sounded to get the fourth underway he charged across the ring and once applied the blowtorch, retaining his IBF Australasian super welter title.

With Brubaker stuck on the ropes, Tszyu let his hands fly and landed heavy shot after heavy shot and trainer Jeff Fenech was left with no other option than to throw in the towel.

Tszyu had comfortably won the opening three rounds of the fight as Brubaker looked helpless to stop the flood of punches being thrown his way.

The win takes Australia’s golden child of boxing to 15-0 and now he’ll eye off a shot at a world title in 2020. Asked about when a shot at the world title might come, Tszyu said he’ll be ready whenever.

“I was just getting started. That was just a warm up I’m just getting started,” Tszyu said after the win.

“We want world titles and we want them in Sydney.

“There’s always room for improvement. I got hit a few times but I think I’m getting better.”

Supremely classy performance from Tim Tszyu. This is such an exciting journey for Australian boxing. All the respect for Jack Brubaker. Jeff Fenech has made it clear he wonât leave his boys in the ring in situations like that. #TszyuBrubaker #boxing — Caden Helmers (@cadenhelmers) December 6, 2019

As dominant as Tszyu was during the main event on the night, it was former NRL big man Darcy Lussick who stole the show with a hellacious finish against a fellow former NRL heavyweight in Justin Hodges.

Lussick making his debut rocked Hodges with a monster right hand that turned his lights off in only 39 seconds.
