Jeetan Patel has signed a one-year contract extension with Warwickshire at the start of his club captaincy.
New Zealand international Patel has now committed to the 2019 season as well as the 2018 County Championship campaign that started on Friday.
The 37-year-old is one of four Bears players to extend terms this week alongside white-ball specialist Oliver Hannon-Dalby, Australian-raised Ryan Sidebottom and all-rounder Alex Thomson.
Patel has won all three domestic trophies with the Midlands county and has twice been named as the English domestic game's Most Valuable Player by the Professional Cricketers' Association.
Ahead of this season, the Kiwi off-spinner had bagged 568 wickets for Warwickshire.
"Jeets has been one of the best overseas players that we've seen in the county game and, having recently been appointed captain, we want to ensure that we have his future secured for the next two seasons," said Warwickshire's director of sport Ashley Giles.
"He has shown outstanding leadership qualities since joining the club, setting a great example on and off the field while also helping the young players with their development.
"We think he will make an excellent captain and look forward to seeing him back on the field in the Bear & Ragged Staff later this week."
The start of Warwickshire's quest to earn promotion from Division Two of the County Championship - against Sussex at Edgbaston - was delayed due to rain.
Warwickshire are 4/1 to beat Sussex while a draw in the season-opener is available at 1/1.
