Fiery Shamsi insists spluttering Proteas still mentally up for Aussie fight as Nortje pulls out

Given that he was the only member of the Proteas attack to front up to a rampant Australian batting order in Saturday's galling 123-run defeat in the 2nd ODI in Bloemfontein, handing Tabraiz Shamsi media duties in the aftermath felt distinctly unfair.

Yet the mercurial left-arm wrist-spinner did so with the courtesy and conviction he showed with the ball - 4/61 in a total of 392/8 is downright superb - and emphatically stated that the struggling South African team remains in the right frame of mind to salvage a five-match series they now trail 0-2.

That objective, however, has been complicated by the news that ace fast bowler Anrich Nortje will, at the very least, miss Tuesday's 3rd ODI in Potchefstroom.

He only completed five overs at the weekend - bleeding 58 runs in the process - before leaving the field complaining of lower back spasms.

Nortje will remain in Johannesburg for scans.

His struggles were emblematic of the Proteas' woes as, for the fifth consecutive match, despite some differing personnel, their bowling was way below par as it lacked incisiveness, discipline and intelligence, putting a rusty but undeniably wasteful batting line-up under inexorable pressure.

"Of course, we're going to have to [take it on the chin] because we aren't producing the results," said Shamsi.

"We're going to have to be accountable for what we're producing. But having said that, we have been working really hard. These results aren't stemming from a lack of work ethic.

"The people doing their work behind the scenes, are doing it. We've got to live with this. In the previous two home series, we beat the Aussies 5-0 and 3-0. The shoe's now on the other foot and we're going to have to make sure now that we come out firing for the last three
