Debutant Lungi Ngidi claimed two late wickets on a costly day for India captain Virat Kohli, as South Africa closed in on a series victory in the second Test at Centurion.
India were set 287 to win after bowling the Proteas out for 258 on day four, Mohammed Shami (4-49) the pick of the bowlers but a stand of 141 from AB de Villiers (80) and Dean Elgar (61) put the Proteas in command.
Captain Faf du Plessis also weighed in with a patient 48 on a surface offering variable bounce, before Ngidi (2-14) and Kasigo Rabada (1-9) reduced the tourists to 35-3 at stumps - 252 runs short of their target.
Ngidi claimed the huge wicket of Kohli, who was earlier fined 25 per cent of his match fee for poor on-field behaviour on day three and looks set to preside over the top-ranked side's first Test series loss for three years.
De Villiers and Elgar had rescued South Africa from 3-2 to 90-2 on Monday and continued to frustrate India in the morning session, the latter not looking comfortable but gaining his reward for digging in when he drove Ishant Sharma to the extra-cover boundary to reach 50.
The brilliant De Villiers deserved a hundred, but the partnership finally ended when the former skipper gloved a rising Shami delivery through to Parthiv Patel and Elgar soon followed, pulling the same bowler to KL Rahul at deep square-leg.
South Africa were 163-5 - leading by 191 - when a pumped-up Shami removed Quinton de Kock (12), but Du Plessis grafted it out after Rahul put down a difficult chance to remove him and Vernon Philander (26) provided support before Ishant (2-40) sent him on his way.
Rabada hung around following Keshav Maharaj's early dismissal but fell before Du Plessis, who struck only four boundaries, was caught and bowled by Jasprit Bumrah (3-70) soon after the paceman gave him another life.
India found themselves deep in the mire after a first wicket for Ravichandran Ashwin (1-78) ended South Africa's second innings, Murali Vijay the first to go, chopping on to a Rabada delivery which kept low.
Ngidi then took centre stage with a hostile spell of fast bowling, although Rahul gifted the 21-year-old his first wicket, tamely steering a short and wide delivery to Maharaj at point.
The Durban-born new boy then claimed the prized scalp of Kohli, the first-innings centurion falling for only five after playing across the line to a delivery which angled in and unsuccessfully reviewed an lbw decision.
Parthiv (five not out) took a nasty blow in the ribs from a hostile short ball from Ngidi, but the wicketkeeper and Cheteshwar Pujara (11no) were still there at the close.
