DURBAN, South Africa (Reuters) - Graeme Swann rocked South Africa with two quick wickets as England continued to dominate the second test at tea on the fourth day on Tuesday.South Africa reached the interval on 37 for two in their second innings, still trailing by 195 runs after England declared on 575 for nine.The home side, number two in the world rankings, were under pressure to survive with 134 overs still remaining in the match.South Africa began their second innings just over an hour before tea and captain Graeme Smith and Ashwell Prince survived the first nine overs in relative comfort.But off-spinner Swann's second delivery deceived left-hander Prince (16) by going straight on with the arm, catching the inside edge of the bat and rebounding off the pad to short-leg, where Ian Bell took a fine low reflex catch.The off-spinner then bowled Hashim Amla for six as the batsman drove loosely and the ball turned sharply through the gate.Smith was the not out batsman at the interval with 15.England declared nine overs after lunch, Bell finishing as top-scorer with a pugnacious 141 before falling to Dale Steyn with the third new ball.Morne Morkel, with three for 78, and JP Duminy, three for 89, were the pick of the South African bowlers.England resumed on 386 for five and South Africa claimed just one wicket in the morning session, Matt Prior falling for 60.Bell, whose place in the team has been under great scrutiny, continued to bat with immense focus and energy, stroking 10 fours and a six in his ninth test century.Bell and Prior extended their sixth-wicket partnership to 112 before Prior's stumps were rattled by an inside edge after he tried an ambitious cut at off-spinner Duminy.The day had started badly for the tourists with Paul Collingwood dislocating a finger during fielding practice.The all-rounder went for an x-ray, which showed no fracture, and Collingwood was given the all-clear to continue playing in the test.The first test was drawn.
