Matt Dunn and Freddie van den Bergh have both signed new contracts at Surrey.
Paceman Dunn, a product of the Surrey Academy, will stay at the Kia Oval until at least the end of the 2017 campaign after penning a three-year deal.
The 22-year-old has impressed with the ball this season, taking 34 wickets in LV= County Championship Division Two.
Van der Bergh, also 22, has signed a new one-year contract.
The left-arm spinner, a graduate from Durham University, made his first-class debut in 2011 and was handed his List A bow earlier this term.
