Sydney: Alex Doolan posted his best first-class score of 161 not out before Australia A declared their first innings at 480 for 7 midway through a three-day match with South Africa.
The Proteas, preparing for the first of three Tests against Australia, were 128 for 1 at stumps on Saturday on the second day at the Sydney Cricket Ground, with captain Graeme Smith not out 60 before he retired to allow other batsmen to the crease.
Hashim Amla (27) and JP Duminy (2) were the not-out batsmen who will resume Sunday on the final day.
Australia A declared their innings minutes away from the nine-hour mark of play, halfway through three six-hour days of play, allowing South Africa some valuable time batting before the Gabba Test in Brisbane begins next Friday.
Doolan featured in a 162-run partnership with Tasmanian teammate Tim Paine (60 not out), the third century stand of the Australia A innings.
Meanwhile, Australia Test allrounder Shane Watson re-injured his troublesome left calf on Saturday while bowling his first over of the day for New South Wales in their domestic Sheffield Shield match with Queensland in Brisbane.
Watson stopped short after his sixth ball and then held a lengthy conversation with Blues' and Australia captain Michael Clarke. He stayed on the field for the following over, but when spinner Stephen O'Keefe dismissed Joe Burns on the next ball, he trudged off Allan Border Field and headed to the dressing room.
Medical staff reported Watson suffered calf soreness and would continue to be assessed.
The latest injury concern comes after Ricky Ponting was withdrawn from Tasmania's domestic match against South Australia on Friday due to hamstring soreness and 19-year-old bowler Pat Cummins was ruled out of the Test summer with a back injury.
