Cape Town - Proteas fast bowler Kagiso Rabada produced a spell of sustained hostility, pace and skill on either side of the tea interval to give the Proteas a strong start on the opening day of the second Test match at St. George's Park on Friday.
But everything changed when Rabada returned to the attack.
After bowling one over from the Duckpond End he switched to the Park Drive end and, starting with the key wicket of Smith, he ran through most of the Australian middle and lower order.
In all he took 5/36 in 8 overs but significantly he took his 5 wickets in the space of 18 balls for just 13 runs.
At one stage he had 4/8 off 7 balls and had the chance to take a hat trick after dismissing Mitchell Marsh and Pat Cummins with successful balls.
It was Rabada's eighth five-wicket haul in only his 28th Test match and his second against Australia.
He was well backed up by Vernon Philander and Lungi Ngidi, who was preferred to Morne Morkel in the only change to the Proteas side, who took the other 5 wickets between them.
This enabled the Proteas to take 5/72 in the second session and 4/73 in the final one.
The only thing that will have disappointed them would have been the fact that the Australian tail was again able to wag to some extent with the last 3 wickets contributing the 73 runs that were scored after the tea interval.
Warner (63 off 100 balls, 9 fours) was the only Australian batsman to get past 50.
Rabada finished with 5/96 from 21 overs, Philander with 2/25 in 18 economical overs and Ngidi with 3/51.
For good measure Rabada also did well as night watchman to get his side through the final 20 minutes without further loss.
The Proteas resume on day 2 on 39/1 with Dean Elgar (11*) and nightwatchman Rabada (17*) in.
Play is scheduled to start at 10:00.
