The 23-year-old maintained his unbeaten pro record on Wednesday night, beating Steven Rados in an epic bout at the WEC.

The crowd began to build up ahead of Sargent-Wilson's fight, which was the third on the undercard for the heavyweight battle between Paul Gallen and Lucas Browne.

There was a huge cheer as Sargent-Wilson - who claimed his first pro win with a first round TKO at the same venue last year - entered the ring for a four round, super middleweight fight.

The bout went the distance, with both men landing some significant blows each round. In the end, Sargent-Wilson claimed a majority decision, taking his pro boxing record to 2-0.

On Thursday morning, the home-grown Illawarra talent was still on cloud nine.

"The head's a bit sore. Got a little bit of a shiner, but apart from that, my body is all good," Sargent-Wilson said.

"It was great. The walk out and hearing the roar of the crowd was unbelievable. I honestly didn't expect to have so many people there cheering me on, but it was great that I could get the win for Wollongong. I thought it was going to be a little bit more convincing (result) than what it was. One judge saw a draw, but I guess that's the way it goes.

"But I'm 2-0 at the WEC, and now 2-0 in my career."

The victory has left Sargent-Wilson hungry for more, after learning a lot from Wednesday night's fight.

"He (Rados) was a real game competitor. We had a couple of different game plans. We knew he was going to be tough and he'd keep throwing punches, and we had to keep switching it up a bit. But that's boxing," he said.

"From the start, I have been chasing six-round fight because I feel like I get better over time. But it's good to get those gritty wins out over the full fight. It also proves to myself that I can do it on the big scale, rather than relying on one big punch."

Sargent-Wilson, who was a golden gloves champion as an amateur in his youth, temporarily stepped away from the sport before returning to the ring last year.

Now 2-0 in his pro career, he enjoyed a well-earned break on Thursday, but was ready to get back into training by Friday. And he is keen for more bouts in 2021.

"As this is pretty much my career now, I'll get back in the gym and look for the next show. We will try get as many fights out through the year as possible," the boxer said.

"I want at least try get four or five, if I can, because I only want to progress. I only want to get better, start taking bigger fights and go from there."
