Ajinkya Rahane continued his brilliant form from the first innings and smashed another century in the second innings to put India in a driver's position against South Africa on the fourth day of the final Test here at the Feroz Shah Kotla Ground on Sunday.
Rahane, who has scored 127 and 100* in this Test, became the fifth Indian batsman to score twin centuries in a Test match.
Resuming at an overnight score of 190-4, India declared their second innings at 267-5, just after Rahane reached to triple figures.
Although Test skipper Virat Kohli failed to score century, he contributed with a significant 88.
For the visitors, Morne Morkel bagged three wickets while Kyle Abbott and Imran Tahir chipped in with a wicket each.
At the stroke of lunch, South Africa were 5-1, and still need another 476 runs to win, which at present seems to be a herculean task.
India, who have already clinched the series following their 124 win over South Africa in Nagpur, are looking forward to a clean sweep.
