• South Africa spearhead Steyn ruled out of series
• Tourist lead by 102 runs with eight wickets in hand
• Australia collapse after openers cruise

Wicketkeeper Peter Nevill managed 23 before Josh Hazlewood (4) and Nathan Lyon, the fourth duck of the innings, fell quickly to wrap up the Australian innings.

Shaun Marsh took a sharp catch at midwicket to dismiss Stephen Cook for 12 off paceman Peter Siddle and Josh Hazlewood bowled Hashim Amla for one, having dismissed him for a duck in the first innings.

But Elgar and Duminy stood firm in the last hour to complete a fine day for South Africa and give the tourists hope of setting a big target on day three.
