Virat Kohli struck a fluent unbeaten 83 to help India overcome a top order collapse and virtually bat South Africa out of the contest on day three of the fourth and final test at the Ferozeshah Kotla Stadium Saturday. Playing his first match as Test captain at his home ground, Kohli partnered Ajinkya Rahane (52 not out) to cobble together the first century stand of the low-scoring series after India had slumped to 57-4 following Morne Morkel's triple strikes. The duo had raised 133 runs for the fifth wicket when bad light stopped play. India's overall lead swelled to 403 against a beleaguered South African team which was shot out for 121 in the first innings and has not gone past 185 in the series. Morkel orchestrated India's top order collapse, claiming two wickets in two balls in the morning after India, which has taken an unassailable 2-0 lead in the series, had opted against enforcing the follow-on and decided to set the visitors a target instead. Morkel drew first blood with a short delivery to dismiss opener Murali Vijay caught behind. The batsman pointed to his arm-guard to suggest he did not nick it before leaving the field shaking his head. Rohit Sharma was sent ahead of Cheteshwar Pujara, who was hit on the arm while fielding at short leg Friday, but the batsman could not justify his promotion. The right-hander, who scored one in the first innings, was out for a golden duck after a fuller Morkel delivery eluded his tentative prod and rearranged his stumps. After the lunch break, Morkel castled Shikhar Dhawan with a searing, in-swinging yorker to dismiss him for 21 while Imran Tahir dismissed Pujara (28). India could have been in bigger trouble when Kohli, then on five, was ruled caught behind only to be called back after TV replays showed the leg-spinner had overstepped. Kohli, hand on hip, was seen glaring at the umpire after being given out initially suggesting he did not nick it in an act of defiance that is unlikely to go unnoticed by the match officials. That was the only blip in an otherwise fluent knock by the Indian captain whose silken touch was in full display in each of the 10 boundaries he hit in his knock. — Reuters
