Sussex vice-captain Chris Nash has signed a new two-year extension at Hove, a deal which will keep him at The PROBIZ County Ground until at least the end of the 2016 season.
The 29-year-old opening batsman has become an integral member of the Sussex side since breaking into the first XI in 2002.
Nash has scored over 10,000 career runs for the Sharks and was named in the PCA Team of the Year at the end of the 2012 season.
Speaking on his new deal, Nash told the club's official website: "I am delighted to have signed for the next four years at the club which I have been at since I was nine.
"Our success over the past decade has been great to be part of and I look forward to continuing that with what is shaping up to be a very strong squad for 2013.
"Personally, I want to continue my good form across all competitions again next season and continue to push for higher honours."
Sussex manager Mark Robinson added: "It is good news for the Club to know that Chris will be here for a minimum of the next four years, as we embark on an important time for the Club.
"It is not only Chris's proven abilities with the bat and ball that we will be relying on, but also his ability to support and lead the team in his role as vice-captain."
