Sri Lankan spinner Ajantha Mendis has added another feather to his cap.

The Lankan mystery spinner has been signed by South Australia for the domestic Twenty20 competition this season.

However, Mendis will not play in the Sheffield Shield or one-day competitions for the Redbacks.

Speaking on this, Jamie Cox, South Australia's high performance manager, said: "It was proven in the World Twenty20 that spin bowling has a massive part to play, and Ajantha was always our No. 1 target."

"The shorter the game the more important it is to have a point of difference and he certainly provides that," added Cox.

Mendis, 24, performed well in the recent World Twenty20 competition in England.

With this, Mendis had joined his team-mate Lasith Malinga (Tasmania), West Indian duo of Dwayne Bravo (Victoria) and Chris Gayle (Western Australia) and Pakistani Shahid Afridi (New South Wales) who signed to play in the tournament.

In IPL Season 2, Mendis represented SRK promoted Kolkata Knight Riders.
