Australia's batting is back under the microscope after Marnus Labuschagne's latest disappointment headlined a collapse to 6-69 at lunch on day four in Gqeberha.
Labuschagne was out for 14 on Wednesday morning, with Marco Jansen's four wickets blowing the door wide open for the Proteas after their first-innings 9(dec)-425.
South Africa can now eye off bowling Australia out for 225 or less to set up a follow on, and pursue victory at St George's Park to level the series at 1-1 with a Test to play.
