India bowled out South Africa for 258 in their second innings—the fourth day of the second Test—and set themselves a 287-run victory target.
AB de Villiers (80) and captain Faf du Plessis (48) were the key contributors for the hosts at the SuperSport Park.
For India, Mohammed Shami was the pick of the bowler, taking 4/49, while Jasprit Bumrah bagged three wickets for 70 runs.
South Africa had resumed on 173 for five after lunch as Du Plessis and Vernon Philander (26) compiled a sixth wicket partnership of 46 from 26 overs, before the latter lost his patience and attempted a hook off Sharma (2-40) that picked out Murali Vijay at mid-wicket.
Keshav Maharaj (6) became Sharma's second victim in the session when he edged to wicketkeeper Parthiv Patel having failed to get in line to a ball that bounced steeply. The slow scoring rate was in contrast to some brisk shot-making in the morning session, despite an excellent spell of bowling from seamer Mohammed Shami (3-42).
AB de Villiers reached 80 before a rising delivery from Shami conjured an edge to Patel. He had put on 141 for the third wicket with opener Dean Elgar, who rode his luck to a half-century before he found Lokesh Rahul in the deep with a well-timed pull shot off Shami and was gone for 61.
Quinton de Kock (12) looked completely out of sorts and after edging three balls in a row past the slips for four, his luck ran out and he brushed a Shami delivery to Patel.
