Wicketkeeper Ben Brown has signed a new two-year contract with Sussex.
Brown is a product of the county's academy and has been a member of the first-team squad since 2007.
The 21-year-old has made 10 first-class apperances and averages 43.15, including two centuries.
Brown played nine times as Sussex secured the Division Two title in 2010 and an instant return to the top flight of the LV County Championship, having been relegated the previous year.
"I'm delighted to have been offered a new deal and to sign the contract, as I'm really looking to press on in the first team next season," Brown told Sussex's official website.
"There's obviously no guaranteed selections but I'm looking forward to hopefully playing in Division One, building on what I've learnt and sealing a regular place.
"I'll be staying here to work hard in the gym over the winter and maybe I'll be able to get some cricket abroad after Christmas to really prepare for the new season."
Sussex captain Michael Yardy welcomed the news of Brown's deal.
"It's great news that Ben has agreed to sign a new contract with the club," he said.
"He has produced some excellent performances this season and is a very important player in our squad on and off the pitch."
