Surrey players Rory Burns, Ben Foakes and Sam Curran have signed new three-year contracts to keep them at The Oval until the end of the 2019 season.
Batsman Burns, 26, Surrey's vice-captain, exceeded 1,000 County Championship runs this year to help the club retain its Division One status after they were promoted in 2015.
Foakes, 23, has established himself as Surrey's first-choice gloveman, prompting former England keeper Steven Davies to leave for Somerset.
Curran, 18, who sometimes opened the bowling with older brother Tom, is a promising all-rounder who, like Foakes, has been named on England Lions' winter programme.
A statement on the club's official website read: "Surrey CCC is happy to announce that vice-captain Rory Burns, wicketkeeper Ben Foakes and all-rounder Sam Curran have all signed new three-year contracts."
