Vincent Barnes, high performance manager of South African cricket and the SA A-coach, applauded the turn and control with which Piedt operated in his five-wicket haul.
He bowled exceptionally well, Barnes said in a telephonic interview from India.
He turned the ball appreciably and took all five wickets with the traditional off-spinner. His first scalp - that of Jinwanjot Singh - was a delivery that turned appreciably from well outside off-stump to knock over middle-stump.
Piedt is a bowler capable of bamboozling batsmen with the so-called doosra or the carrom delivery, but he did not need those variations to cause havoc at the Krishnagin Stadium in Wayanad in the first unofficial test between South Africa A and India A.
Barnes said when Piedt was first introduced for South Africa A against the England Lions following a prolonged period on the side-lines due to the rehabilitation on his shoulder, he might have rushed himself back and he was not strong enough.
“He worked hard on his action and his strength in the winter with Paul Adams,” said Barnes.
“From a South African point of view, it is encouraging to have all these spinners. It is healthy to have this competition. Dane has put his hand up (with the performance against India A).
“Keshav (Maharaj) operated well and was the perfect foil for Dane,” the SA A-coach added.
The Cape Cobras won the domestic four-day showpiece during the 2012/13- and 2013/2014-competition, but relinquished the crown in the 2014/2015-season.
Piedt nipped out 45 batsmen in eight matches during the 2013/2014-campaign. Subsequently,Piedt made a highly promising test debut in Harare, claiming eight for 152 in his maiden match.
Piedt fell on his shoulder while representing the Cape Cobras in the Champions League T20-tournament in India.
Piedt captured four wickets in five Sunfoil Series matches in the 2014/2015-season. He was plagued by self-doubt and inconsistency and also struggled a tad for South Africa A against the England Lions upon his return.
“His performance against India A is a step in the right direction. Now it is about maintaining this performance,” said a delighted Adams, former South African wrist spinner and Cape Cobras coach.
