Teenager Tom McCartin's rapid development with the Sydney Swans has earned him a new two-year contract.
The 18-year-old played 15 games in his debut AFL campaign, after being needed at senior level sooner than expected.
Sam Reid's injury gave him the opportunity and he was one of a number of youngsters at the club to catch the eye.
John Longmire's club made a success of their decision to turn to youth this year; besides McCartin they had Tom Papley, Ben Ronke and Will Hayward playing in the forward half.
McCartin, who was the youngest player selected in last year's AFL draft, will now stay with the Swans until at least the end of the 2021 season.
He said he'd been helped by having Lance Franklin at the club, as he'd been able to learn from the superstar forward on a weekly basis.
"Being around the older boys like 'Buddy' and watching how they go about it and what it takes (to succeed) has been great, and I was able to play a few games this year," he said.
"I'm just looking to a big pre-season and improving on the things I need to get better at, and hopefully I can get a few again next year. I'm pumped and really excited to sign on for another two years."
The Swans have sought to maintain a balance between youth and experience, having re-signed veterans Jarrad McVeigh and Heath Grundy earlier this year.
The club's football boss Tom Harley said McCartin had demonstrated he had a bright future at the Swans.
"For an 18-year-old to hold down a key-position post for more than half the season in his debut year is an unbelievable achievement," added Harley.
Meanwhile, reigning premiers Richmond are 21/50 to beat Collingwood in their preliminary final, with the Magpies 2/1.
