Captain Gary Wilson and veteran off-spinner Gareth Batty are among seven players to pen new long-term contracts at Surrey.
Wilson, former skipper Batty and fast bowler Stuart Meaker have all agreed two-year deals - while Zafar Ansari, Rory Burns, Tom Curran and Dominic Sibley have signed up for three.
Surrey director of cricket Alec Stewart told his club's official website: "We are delighted that these contracts have been finalised and that each player has committed their future to Surrey CCC.
"Ansari, Burns, Curran, Sibley and Meaker have all come through our academy system - and we now have an exciting blend of home-grown talent and experience in our squad heading into the 2015 season".
