South Africa were 134/3 overnight. The day four morning had some rain which stopped the play for a while. Dean Elgar and his skipper Faf du Plessis put on 170 runs for the fourth-wicket.
du Plessis reached his 8th Test hundred in 163 balls. He amassed 120 runs from 178 deliveries including 18 fours and 2 sixes. Elgar made a steady 81 off 250 with 10 fours and a six.
South Africa piled on more runs until tea break. Temba Bavuma scored 40-ball 35* while Vernon Philander contributed valuable 33* runs. The Proteas declared at 344/6 in 105 overs. Pat Cummins bagged four wickets for the Aussies.
In reply, Matt Renshaw survived a first-ball dismissal after he opted for a review. However, he was soon trapped lbw by Morne Morkel, who was bowling with some pace off. Usman Khawaja failed to contribute.
Joe Burns made 42 runs off 80 balls with 5 fours and a six. He was also given lbw off Morkel. Australia ended day four on 88/3 in 30 overs. Peter Handscomb (23*) and Shaun Marsh (7*) are at the crease.
Australia need 524 runs with seven wickets remaining to level series 2-2. Currently, South Africa are leading the series by 2-1. If this match is won by the Proteas or drawn this will be the first time South Africa winning a Test series against Australia at home.
