Melbourne, Mar. 24 : Former Australian leg spinner and Shane Warne's guru Terry Jenner believes that current Australian leg spinner Bryce McGain has ruined his chances of an Ashes call-up with his performance in the Cape Town Test.

McGain, who turns 37 tomorrow, was clobbered for 149 runs in 18 wicketless overs as Australia lost to the Proteas by an innings and 20 runs.

Jenner, the mentor of Shane Warne, insisted McGain was "a better bowler than that" but suspected selectors would not overlook the leg spinner''s "nightmare" performance.

"That''s the only way you can describe it: it was a nightmare. Unfortunately, when spinners get those nightmares they rarely get another chance. I feel for him but I can''t quite see where the selectors can go with him at the moment," the Sydney Morning Herald quoted Jenner, as saying.

Jenner believed McGain must still be hampered by the shoulder injury that sidelined him for the last three months of 2008.

"He''s obviously not recovered from that shoulder operation because he didn''t spin anything. Nothing spun. When he came around the wicket he just kept hitting the middle of the bat, and that''s not right. Bryce McGain is better than that," he said. (ANI)
