Durham all-rounder Brydon Carse has signed a new three-year contract to keep him at the Riverside until 2021.
The 23-year-old made his first-class debut for Durham in 2016 but has not featured for the county at all this season due to a knee injury.
"I'm delighted to have signed a new deal with Durham," the South African told the club's official website.
"I enjoy living in the North East and the Emirates Riverside is a special place to play cricket."
Carse took 17 wickets in eight matches during his first season and has also averaged 38.14 with the bat in first class cricket.
He continued: "I believe the club is on the way up and following conversations with my dad, [head coach] Jon Lewis and new chief executive Tim Bostock, I'm convinced that this is the best place for me to continue to develop my cricket and compete for silverware."
