South Africa have been bowled out for 253 following a late surge from Pakistan on day one of the first Test in Johannesburg.
The Proteas, who headed into the series as the world's best Test team, took to the crease with Graeme Smith, who has become the only player to captain 100 Test matches, and Alviro Petersen.
The pair had a steady start and looked set to rack up a large total for their side until Petersen was dismissed for 20 and Smith on 24 in quick succession by lunch.
Jacques Kallis kept South Africa rumbling along by reaching a half-century before Umar Gul ended his time at the crease, while Hashim Amla managed 37 from 67 balls.
Pakistan managed to find their rhythm in the evening session by snatching four wickets, which included Robin Petersen getting bowled out for a duck by Mohammad Hafeez.
Vernon Philander was dismissed for one, while Morne Morkel was bowled out for a duck, which ended South Africa's innings with Dale Steyn unbeaten on 12.
