England Under 19 all-rounder Ben Stokes has signed a two-year contract with Durham.
Stokes, 18, is a product of the Durham academy and made three one-day appearances for the county's first team in 2009.
He is part of England's squad for the Under 19 World Cup in New Zealand in January.
"It's been an exciting few weeks for me and I'm really happy to have signed my first professional contract," Stokes told Durham's official website.
"It's great to be involved with such a successful club and it's been a real benefit to have a varied group of players around me who I can go to for advice. I can't wait for the 2010 season to start!"
Durham head coach Geoff Cook added: "We set Ben a number of challenging targets for the 2009 season and he worked incredibly hard to meet them.
"The transition from Academy to second XI and on to the first team can be a tough one but I have been impressed by the way he has performed.
"He's a great young talent and I'm pleased that he's going to be part of the squad for the foreseeable future."
