He will remain skipper of Australia’s Test and one-day sides, but is stepping away from the shortest form of the game.“The last 10 or 12 days for me have been a lot about reflection, looking back to the Ashes and looking forward to my playing future,” Ponting said.
"I’m really passionate and committed to being the best player I can be for Australia for as long as possible."Over the last couple of years I have found it increasingly difficult to play all three forms of the game at the level that I want to play them."Ponting said he would gain an extra four weeks break over the next year by not participating in Twenty20 fixtures.
Michael Clarke is set to assume leadership of the side.Ponting left Sydney this afternoon to rejoin the Australian squad for the remaining games of the one-day series in England and the ICC Champions Trophy in South Africa.
This may be offtopic ..but i think Yousuf should also follow ponting and younis step
If he is not stupid he would have gotten the hint by now
(P.S. Yousuf announcing his retirement from T20 makes little sense since he has not played any T20 cricket for Pakistan. One could argue that he's already retired from this format!)
