Off-spinner Graeme Swann claimed five wickets for the second time in the series as England beat South Africa by an innings and 98 runs in the first session of the fifth day of the second Test on Wednesday. South Africa were dismissed for 133 in their second innings after adding just 57 runs before losing its last four wickets just 70 minutes into the final days play. Swann finished off the match by trapping tailender Dale Steyn leg-before for three runs to finish with figures of 5-45 and claim the Man of the Match award for the second time in the series. Swann has now taken 14 wickets in the first two Tests. South Africa had staggered to 76-6 by stumps on the fourth day needing 156 runs to make England bat a second time. Englands first success of the morning came after just 11 balls when Swann forced Morne Morkel back onto his stumps and trapped him in front for 15 with a quicker ball. Morkel had batted grittily for 51 minutes starting on Tuesday afternoon and hit three fours. Next to go was Mark Boucher,giving seamer Stuart Broad his fourth wicket of the innings. Boucher gloved the ball down leg to wicketkeeper Matt Prior,but England had to wait for third umpire Steve Davis to call it out after on field umpire Ameesh Saheba originally called it not. Bouchers 29,with three fours,came in 91 minutes. Paul Harris batted for an hour to make 36,the highest score of the innings,before he was the ninth man out. Eight balls later Swann struck the final blow by getting Steyn. After the first Test in Pretoria ended in a draw,Wednesdays win puts England 1-0 up in the four-match series,with the third Test starting in Cape Town on January 3. South Africa will reflect that that they were simply outplayed by England,whose bowlers were more effective. The Proteas top six batsmen,too,will realise that they owe the team a big effort in the third Test. Brief scores: South Africa 343 and 133 all out (Paul Harris 36,Mark Boucher 29; Graeme Swann 5/54,Stuart Broad 4/43)
