Cape Town - Pressure mounted on Australia on Day 3 of the first Test match at the WACA ground in Perth as JP Duminy and Dean Elgar both moved to their fifth Test centuries during the second session of play.
South Africa ended the session on 295/3, a lead of 293 over the home side.
Duminy was first to reach his century, which came off 170 balls as he drove Mitchell Marsh for 2 runs through the covers. His ton included 17 fluent boundaries.
Elgar was far more circumspect with the opener prepared to be the rock on which the Proteas built their innings. His ton came up off 255 balls and included twelve boundaries and a six.
Duminy fell in the last over before tea chasing a wider delivery from Peter Siddle only to get a faint edge behind. He was initially given not out but the decision was overturned after Australia chose to review.
He scored 141 off 225 ball with 20 boundaries and a six and had put on 250 for the third wicket with Elgar.
