Duminy, Elgar centuries put Proteas on top against Oz

Australia removed both centurions around the tea break, as well as Temba Bavuma and captain Faf du Plessis in the last hour, but by then the damage had been done and the Proteas will go into day four on 390 for six. Quinton de Kock, who was dropped by Adam Voges on one, was at the crease unbeaten on 16 at the end of a long, hot day at the WACA, along with Vernon Philander, who had made 23 not out.

South African paceman Dale Steyn was ruled out of the rest of the series with a fractured shoulder on Friday and will play no further part in the match, reducing the number of wickets Australia need to take. Duminy faced 225 balls and hit 20 of them for fours with another going for six, overhauling partner Elgar before lunch and reaching his fifth test century with two runs to deep cover soon after the break. It was his first century in two years and his third against Australia.

Brief scores: South Africa 242 & 390/6 (Duminy 141, Elgar 127, Siddle 2/47) vs Australia 244
