Steyn took six for eight in 8.1 overs as Pakistan were shot out for 49, four fewer than their previous lowest total of 53 against Australia in Sharjah in
2002-03.u00a0South Africa led by 204 runs on the first innings but decided not to enforce the follow on.

The hosts were 207 for three in their second innings at the close, an overall lead of 411, with Graeme Smith (52), Hashim Amla (50 not out) and AB de Villiers (63 not out) hitting half-centuries.

It was another triumph for South Africa's barrage of fast bowlers and the third time in less than two seasons that the world's number one Test team had bowled out opponents for less than 50.

Australia were routed out for 47 in 2011-12 and New Zealand were dismissed for 45 earlier this season.u00a0Both matches were in Cape Town.

AB de Villiers equalled the South African wicketkeeping record by holding six catches and there were three catches in the slips as the Pakistan batsmen failed to cope with top quality bowling on a pitch with steep and sometimes variable bounce as well as some sideways movement.

Vernon Philander took two for 16 and Jacques Kallis two for 11.u00a0Azhar Ali (13) and captain Misbah-ul-Haq (12) were the only Pakistan batsmen to reach double figures.u00a0
