Hawthorn have secured teenage wingman Bradley Hill for another four AFL seasons.

The 19-year-old pacey West Australian has signed with the Hawks until the end of the 2017 season.

Hill played just five games in 2012 after the Hawks took him at pick 33 in the 2011 draft.

Last season, he played 24 games, including Hawthorn’s grand final success.

He became the first man in 100 years to defeat a brother, Fremantle’s Stephen Hill, in last year’s decider.

Hill said he didn’t believe he would have made his AFL debut by then.

“When we won it last year, it was a shock. It didn’t really feel real … I didn’t even expect to play AFL footy in my first couple of seasons,” he said.

“I wanted to have a really big pre-season to get ready for 2014 and hopefully do the same this year.”

“This year, I’ve had an extra pre-season into me so I feel a lot fitter and now I’m even more confident than last year so I can take the game on a bit more.”
