Spearheaded by Dale Steyn (pictured), the Proteas captured three wickets cheaply midway through the first session
Australia A recovered from an early setback to thwart South Africa's Test-strength bowling attack on the opening day of their three-day tour match at the Sydney Cricket Ground on Friday.
Australia A fought back from 44 for three in the 14th over to be 325 for seven off 90 overs at the close after winning the toss in the tour warm-up game before next week's opening Test in Brisbane.
Spearheaded by premier paceman Dale Steyn, the Proteas started strongly, capturing three wickets cheaply midway through the first session.
But a 122-run stand between opener Rob Quiney (85) and Steve Smith (67) lifted Australia A.
Upon the quick dismissals of Quiney and Smith Australia A slumped to 185 for six before another rebuilding partnership of 133 between Glenn Maxwell (64) and Alex Doolan (76 not out) saw the Australian selection through until the final few overs of the day.
What began as an encouraging day for South Africa's vaunted pace brigade fell away to a long day in the field.
Steyn remained the pick of the bowlers, finishing with 3-43, while Rory Kleinveldt snared 2-45.
Imran Tahir bowled better than his figures of 2-114 off 28 overs.
It was a forgettable day for third paceman Vernon Philander, the No.2 ranked bowler in Test cricket, who failed to take a wicket and finished with 0-76 from 16 overs.
Maxwell was the aggressor after tea, hammering the spin trio of Tahir, JP Duminy and Faf du Plessis as he smashed eight fours before being caught behind off Steyn.
Quiney hit 13 boundaries to top-score on the opening day.
Steyn produced the pick of the wickets, clean bowling opener Liam Davis (10) with a gem of a delivery that pitched on middle and beat the bat before clipping off-stump.
Former Test opener Phil Hughes (5) and captain Andrew McDonald (0) went cheaply before Australia A regrouped.
Quiney looked sharp before he was brought undone by Steyn, who enticed an edge to Graeme Smith at first slip, while Steve Smith (67) lasted just three more overs before he became Tahir's second LBW victim of the day.
Jacques Kallis, recovering from a chest infection, and Morne Morkel were rested from an otherwise full-strength South African team, though Kallis came on as a replacement fielder late in the day.
