Australian seamer and former Test player Stuart Clark announced his retirement from international and state cricket on Wednesday.
The 35-year-old will instead focus on his new role as general manager of the Sydney Sixers in a new eight-team, city-based Twenty20 domestic competition starting this summer.
He will continue playing club cricket for Sydney University.
"I am going to continue playing club cricket as I still love playing the game, but more importantly I believe I can still help develop Australia's future talent," said Clark, who played 24 Tests, taking 94 wickets at 23.86."
"Playing cricket has given me many opportunities in life and I feel by continuing to play club cricket I am giving something back to the game."
"The Sydney Sixers is now my professional focus, however."
Clark, who captained New South Wales in Simon Katich's absence last summer, also played in 39 one-dayers, taking 53 wickets at 27.86.
