Chris Rushworth has extended his contract at Durham until the end of the 2014 County Championship season.
The 26-year-old enjoyed a prolific 2012 season, with third highest bowling average behind Somerset's Abdur Rehman and team-mate Graham Onions.
"I'm delighted to sign a new contract extension with Durham," Rushworth said.
"2012 was tough but on a personal level I was delighted to take 38 championship wickets, and felt for the first time I'd really established myself."
Sunderland-born Rushworth, an academy product at Durham, made his first-class debut in 2010 and has since played 21 first-class games.
"I'm hoping to push on to the next level in 2013," Rushworth added.
"It's a huge year for the club and hopefully we can perform to the levels we know we can and bring some silverware back to Durham."
