The Mandurah resident won the 52kg Youth State Novice Title in Scarborough with a thrilling victory against Mason Frost.
A talented junior football player, Winwood (16) said he would focus on boxing in a bid to hone his skills.
‘I want to concentrate on boxing,’ he said.
‘There is a lot of hard work to do and I am really looking forward to doing more training.
‘I hope to compete in more fights so I can keep improving. I am dedicated to getting better and one day I would love to compete at the Olympics.’
Winwood said he was training about four times a week at Eureka Boxing Club in Silver Sands.
Trainer Brian Sartori said Winwood was a ‘special talent’.
‘He coped really well in Scarborough and was not overawed by stepping into the ring,’ he said.
‘Alex is a hard worker. He has speed and power for his size.
‘He is a thinker in the ring, which he can use to his advantage.’
Sartori believed more experience in the ring would hasten Winwood’s development.
‘We hope to get Alex a few more fights before the end of the year,’ he said. ‘More sparring will also help.’
A re-match is expected between Winwood and Frost in the near future.
