'Playing for their careers' - Australia reeling after extraordinary day

Australia are facing defeat in the second Test against South Africa with careers on the line after their shambolic performance on day four.

Australia had South Africa 110-6 on day three but are now facing defeat

Not since the Nottingham Ashes Test in 2005, Shane Warne's spin and watching Ashley Giles' leg glance from behind a cushion, had Australia been asked to follow-on in an away Test.

It had only happened to them on one other occasion anywhere in the world in 38 years.

But by being bowled out for 99 by South Africa in their first innings of the second Test, Australia matched those lows and handed their hosts an unlikely route to winning this Test and leveling the series.

Travis Head remains on 87 not out, but this was a calamitous day for the tourists as they conceded their biggest first-innings lead since 1984, before failing for the second time in the same day's play.

At 156-4 in their second innings they are still 170 runs behind and the Proteas now look likely winners with a day to go.
