Warwickshire batsman Will Porterfield has signed a two-year contract extension with the County Championship Division One champions.
Ireland captain Porterfield's current deal was due to run out at the end of next summer.
The 28-year-old has made 72 appearances in all competitions for Warwickshire since joining them from Gloucestershire two years ago.
Porterfield averaged 24.10 in the County Championship last season and played an important role in the county's run to the Clydesdale Bank 40 final.
"I've had two fantastic seasons already with Warwickshire and with such a strong squad and a great chance to win more silverware, it was an easy decision to extend my stay here at Edgbaston," said Porterfield. "The majority of the squad has been playing together for a few seasons and we're all really looking forward to competing for more honours in the new season."
Warwickshire director of cricket Dougie Brown said: "Because of a reduced international calendar, this is the first winter where we've seen a lot of William here at Edgbaston.
"His attitude and commitment towards pre-season training has made a great impact on other members of the squad. He's made great strides in the last few months and we had no hesitation in offering him a chance to commit himself to Warwickshire for the foreseeable future.
"His opening stand of 126 with Varun Chopra in the CB40 semi-final at Old Trafford demonstrated his maturity and ability to perform on the biggest stage.
"His challenge is to do this consistently across all formats of the game and prove himself to be one of the leading batsmen in the domestic game."
Brown also wants all-rounder Rikki Clarke to sign a new contract at the club.
Clarke, who has played in two Tests and 20 ODIs for England is currently part of the Lions squad touring Australia and Brown is keen to open talks with the 31-year-old when he returns.
"Rikki is a crucial member of the squad and we would be delighted if he signed an extension," said Brown, who succeeded Ashley Giles as Warwickshire director of cricket in January.
"While he is in Australia with the England Lions, he will be concentrating on that. But it (the new contract) is something we will be looking to get on to straight after he gets back."
