Jamie Semple has extended his contract with Motherwell until the summer of 2021.
The youngster is the latest academy product to commit his future to the club, following in the recent footsteps of David Turnbull, James Scott, Barry Maguire and Adam Livingstone.
The 17-year-old also made his first appearance on the bench against Rangers on 7 April, becoming the first player born in 2001 to do so.
“I’m really happy to be staying at the club,” Semple said on signing his new deal.
“I can see a clear way through to the first team, having seen so many of my team mates progress over the last few years.
“I’m concentrating now on continuing to develop my game and kicking on. I’m in the best place possible to do that.”
Semple first joined the club in 2014 and has established himself as a key figure at reserve level. He made his debut for the second string at the age of 14, demonstrating his promise.
“Jamie is a player who has made great progress,” manager Stephen Robinson said.
“We feel he is another youngster who, in the coming years, can make a big impact at the club.”
