Brief Scores Pakistan 185 (Sarfraz 50, Olivier 5-51) and 153 for 3 (Shafiq 48 n.o., Babar 17 n.o.) need another 228 to beat South Africa 262 and 303 (de Kock 129, Amla 71) South Africa moved ever closer to a 3-0 clean sweep on the third day at Johannesburg, as Dale Steyn and Duanne Olivier bent their backs in the face of some stiff resistance to leave Pakistan's second innings in the balance at 153 for 3, and ensure that Quinton de Kock's superb fourth Test century is unlikely to go to waste.

The loss of both openers in the space of three Steyn overs set the scene for another critical failure for Azhar Ali, their under-performing senior batsman, who completed a dismal series haul of 59 runs at 9.83 when he was bounced out for the fourth time in six innings by Olivier. It was Olivier's 22nd wicket of the series, more than even Steyn has ever managed for South Africa in a three-match series, and it had to be hard-earned on a surface that appeared to lack the demons that had been in evidence while de Kock and Hashim Amla, in particular, were eking out their team's lead in the early part of the day. In the absence once again of a frontline spinner to mix up South Africa's options, it took invention and nous to force their openings in the evening session - not least from Steyn, who had left the field clutching his shoulder in the first innings, but shook off any lingering doubts about his fitness with another bravura performance.
