Perth: South Africa, fired by a devastating spell of bowling from Dale Steyn and sustained by the batting of Hashim Amla, took a firm grip on the third and final Test against Australia on Saturday to end day two with an imposing lead of 292.
Amla finished the day one run short of his 18th Test century with South Africa on 230 for two after paceman Steyn had taken (4/40) as the bowlers dismissed the hosts for 163 for a first innings lead of 62.
Captain Graeme Smith put on 178 for the second wicket with Amla before departing for 84 to leave Jacques Kallis, who had made 17 not out, to resume on Sunday.
Australia had started the day on 33 for two in front of a bumper Waca crowd hoping to see Ricky Ponting score a century in his penultimate innings and drive his country towards a series victory and the No. 1 ranking that would go with it.
Their hopes lasted less than 40 minutes as Steyn, who took three wickets at the cost of just four runs in the morning session, and his fellow quicks Vernon Philander (2/55) and Morne Morkel (1/19) unleashed the barrage the Australians had feared all series.
The first ball of the Steyn's first over dispatched opener David Warner caught behind for 13 after a fruitless TV appeal, while his fourth sent nightwatchman Nathan Lyon back to the pavilion for seven.
Ponting, who had been welcomed by a standing ovation, managed just four runs when he was trapped lbw by Philander, his subsequent appeal to the TV umpire having less merit than Warner's but proving just as fruitless.
