Fast bowler George Garton has signed a two-year contract extension with Sussex, and will remain at Hove until the end of the 2020 season.
The 20-year-old left-armer made his first-class debut in 2016 and has taken 46 wickets in 30 matches for the club across all formats.
Brighton-born Garton joined Sussex at under-10 level.
He has featured six times for England Lions and is part of the squad which is touring Australia this winter.
“George has pace, which is a valuable asset, and his white ball skills are developing quickly,” Sussex director of cricket Keith Greenfield said.
“He has come through our system and we want to make sure he continues to grow and fulfils his potential with us.”
