Elgar will retire from international cricket after next week’s clash in Cape Town and offered a fitting reminder of his qualities with a polished 140 not out – his first Proteas ton in nearly three years.
The 36-year-old occupied the crease for 66 overs, facing 211 deliveries and cracking 23 fours to lead his side to 256 for five. That put South Africa into a narrow lead of 11, with the tourists having earlier been bowled out for 245.
KL Rahul, resuming on 70 overnight, completed a superb century of his own as he scored 31 of his side’s 37 runs in the morning session. He was last man out, bowled by debutant Nadre Burger, having almost single-handedly kept India competitive.
With Elgar holding firm at the top of the order and captain Temba Bavuma absent with a hamstring injury, India successfully chipped away Aiden Markram, Tony de Zorzi and Keegan Petersen to leave the hosts 113 for three.
But another newcomer, Durham batter David Bedingham, helped South Africa press ahead with an elegant 56 in his maiden Test innings. He put on 131 alongside Elgar, who brought up his 14th hundred, before being cleaned up by Mohamed Siraj.
Kyle Verreyne followed as Prasidh Krishna opened his account as a Test bowler before bad light brought an early finish.
More wickets have fallen in a single day just four times in the history of Test cricket, with ball dominating bat throughout three breathless sessions that ushered the game towards a rapid conclusion at Newlands.
At stumps South Africa were 62 for three in the second innings, only 36 behind after India had lost their last six wickets for no runs in the space of 11 deliveries. From 153 for four they were rounded up in successive overs by the inspired pairing of Lungi Ngidi and Kagiso Rabada without adding to their total.
Dean Elgar, South Africa’s retiring stand-in captain, suffered the ignominy of ending his international batting career with two dismissals on the same day but at least shared that pain with team-mates Tony de Zorzi and Tristan Stubbs.
Elgar had won the toss and opted to bat in the morning but saw his decision blow up spectacularly as India skittled the hosts for their lowest Test score in 92 years.
Mohammed Siraj did most of the damage with figures of six for 15, with two apiece for Jasprit Bumrah and Mukesh Kumar, the latter without conceding a run, as the innings subsided in less than 24 overs.
India took the lead in just 10 overs after lunch, Rohit Sharma taking the attack to the home seamers with a rapid 39. The tourists were primed to hammer home a big advantage at 105 for two with Shubman Gill (36) and Virat Kohli (46) at the crease, but there was another twist in the tale.
Things took a huge handbrake turn in the 33rd over when Ngidi dismissed KL Rahul, Ravindra Jadeja and Bumrah in a triple-wicket maiden.
Unbelievably, three more fell in the next five deliveries at the other end, Rabada taking care of Kohli and Prasidh Krishna either side of Siraj’s run out.
The third innings of the day got under way in the evening session, Kumar picking up two more and Bumrah adding a third as Aiden Markram’s 36 not out offered some belated resistance from the Proteas.
