Former England opener Marcus Trescothick has signed a new one-year deal with Somerset.
The 39-year-old has spent his entire career with his home county since making his first-class debut in 1993.
Max Waller, Jack Leach and Josh Davey have also agreed new deals at Taunton alongside club captain Trescothick.
"Marcus is the absolute model professional," Somerset director of cricket Matthew Maynard told BBC Sport. "He has contributed a tremendous amount to this club.
"Whilst he is coming to the twilight of his career on the field his experience and knowledge are second to none and he still has a very important role to play both on and off the field."
Trescothick played 76 Tests, 123 one-day internationals and three Twenty20 matches for England.
