London: An inspired bowling display helped South Africa fight back on the second day of the first Test at The Oval.
England appeared to be on course for a large first-innings total after resuming on 267-3, but they lost their last seven wickets for 114 runs at the hands of an impressive Proteas attack.
Dale Steyn did the early damage, dismissing Alastair Cook for 115 and Ravi Bopara for a six-ball duck, and it took a battling half-century from Matt Prior to help England reach 385. Morne Morkel finished with 4-72.
James Anderson removed South Africa opener Alviro Petersen without score in helpful conditions but, after a rain break, the ball stopped moving around and Graeme Smith (37 not out) and Hashim Amla (47 not out) carried the tourists to 86-1 by the close.
Earlier, South Africa roared back into the first Test at the Oval on Friday, dismissing England for 385 after the hosts were 267-3 overnight.
Matt Prior hit 60, from 90 balls with nine fours, but South Africa took England's last seven wickets for 134 runs.
Morne Morkel was the pick of the bowlers with figures of 4-74, while Dale Steyn (2-99), took two wickets in seven balls including that of Alastair Cook, who was bowled for 115 having added just a single to his overnight total.
Jacques Kallis claimed 2-38 and wicketkeeper AB de Villiers took five catches.
The key wicket of Cook came in the fifth over of the morning, when he played on to his stumps and was bowled by Steyn.
Steyn then removed Ravi Bopara, recalled for this match after a year out of England's Test side.
Bopara lasted just six balls before he wafted his bat at a Steyn bouncer and was caught behind for a duck.
Having toiled throughout day one, South Africa's bowlers exploited the overcast conditions to swing the ball both ways and stifle the batsmen.
Steyn in particular looked like taking a wicket with every delivery, but in an inspired piece of captaincy Graeme Smith replaced him from the Vauxhall End with Jacques Kallis.
Kallis' fourth ball clipped the top of Ian Bell's off bail, bowling him for 13 and things could have been worse for England had Jacques Rudolph held a difficult chance when Prior edged Morne Morkel to gully.
Tim Bresnan (8) lasted 32 balls before he chopped Imran Tahir's third ball of the morning on to his stumps but having lost 4-59 during the morning session England countered after lunch.
Prior reached 50 with a straight drive off Vernon Philander, but Philander then bowled Stuart Broad for 16, ending a useful stand of 45 for the seventh wicket.
Prior eventually got the faintest nick to Morkel and was caught behind and Morkel wrapped up the innings four balls later when James Anderson (2) became de Villers' fifth victim.
