Wicketkeeper Andrew Hodd has agreed a new two-year contract with Sussex.
The Chichester-born 26-year-old has made four centuries during his five years at Hove and averages 29.57 in first-class cricket.
Assuming Matt Prior is away on England duty for most of next summer, Hodd and Ben Brown will battle it out for the gloves.
Brown also recently signed a new deal with the county after they won Division Two of the LV County Championship in 2010.
"I want to help the club move forward as much as possible," Hodd told Sussex's official website.
"Obviously we've gone up to Division One and we're serious about putting a title challenge in.
"I want to do myself justice and perform to the best of my ability. I'm definitely looking to cement my place in the side in all three formats of the game.
"One-day cricket worked quite well for me last year, but my Championship form fell off a little bit and I also got healthy competition from Ben.
"I think that is good for the both of us and hopefully it will spur me on to improve my game."
Sussex coach Mark Robinson challenged Hodd to turn his promise into consistent production.
"Everybody knows that Hoddy has it in him to be an outstanding wicketkeeper-batsman, and it is now up to him to produce the results and justify his undoubted talent," said Robinson.
