HE'S already a state footballer and gun cricketer, but now Jye Caldwell can add Victorian boxing champ to his burgeoning list of sporting achievements.

Last week, Caldwell stepped into the ring for his first fight and when he ducked under the ropes again he was the new 54kg schoolboy titleholder.

The Bendigo 13-year-old overcame Colerain's Toby Walter in a tough fight in Melbourne, just six months after his first workout at Danniel Burton's Hit Factory gym.

"Even just to get in the ring after six months is pretty extraordinary, I suppose just having that natural sporting ability really helps," Burton said.

"He's obviously got a bit of natural talent, a bit of an edge for competition.

"So as soon as he got in you could tell he had the co-ordination and it was just about honing his skills.

"Boxing's the most challenging sport and for a kid like that, he always needs a challenge.

"It was a good fight and we knew it would be.

"He fought a boy from Coleraine and every time you fight someone from that gym, you know it's a tough fight.

"They're always well schooled, pretty tough and we knew that, but we also knew Jye was a good boxer."

Caldwell and his best mate Lachie Johnson spar together at Hit Factory, and this weekend Johnson will fight for the 52kg title.

"These two boys train together, they spar together and they really push each other along," Burton said.

Caldwell started boxing to keep fit after having problems with his feet, but Burton expects he will be keen to fight on after his first taste.

"I think once boxing's in your blood, it stays there - he's definitely got the bug," Burton said.

"He enjoys it and he wants to keep going."
