Clarke has impressed enough to earn a new two-year deal, despite only a handful of first team appearances.
The 22-year-old has been involved with England at youth level and is predicted to have a big future in the game.
Clarke is technically the first signing of manager Ian Atkins, since he took charge at The Memorial Stadium.
