Ryan Sidebottom has signed a one-year contract extension that will keep him with Yorkshire until December 2015.
The 35-year-old former England left-arm seamer, who is in his second spell with his home county, has taken over 50 wickets during the campaign - 46 coming in the LV= County Championship - as the White Rose have fought with Durham for the title.
His current deal expired at the end of next season but he will now remain with Yorkshire for at least another two years.
"I am delighted to be committing my future to Yorkshire,” said Sidebottom.
"This is the best club in the world and I feel we are going places. We have some great young lads coming through and they are improving every year.
"I believe within the next couple of years we will win some silverware. With the quality of personnel we have coming through we will be amongst the best teams in the country.
"From a personal point of view, I’m feeling very fresh and fit. I am bowling well and enjoy playing. The guys are pulling me along and the backroom staff are managing my workload and I am feeling the benefit.
"There is no reason why I can’t go on beyond 2015. I’m certainly not even thinking about retirement. It hasn’t even crossed my mind.
"I want to finish my career at Yorkshire. This is my club and to be part of Yorkshire’s future success is something that gives me great pride. The club have put their faith in me and I want to repay them by taking lots of wickets and developing a winning culture.”
Yorkshire director of cricket Martyn Moxon added: "We are very happy that Ryan has signed until at least 2015.
"He has been an exceptional, consistent performer again this season and we hope he will play as long as it is physically possible for him to do so.
"He brings so much to the dressing room. He still remains one of our most consistent performers and his experience is second to none. We want him to mentor our young bowlers and pass on his wisdom.
"He is keen to play as long as he can. Hopefully, he’ll be ready and able beyond a couple of years. It is difficult with a fast bowler to know how long they can go on, but with Ryan he is like a fine red wine and he seems to be getting better and better with age.
"He is fully committed to Yorkshire and we want him to be part of our plans for many years to come. I can see him ending his playing days here."
