What he did in the middle session was his natural captaincy.
Speaking to reporters after the day's play, Shami didn't take kindly to questions about his inconsistent bowling in this series before the second innings in Centurion.
India vs South Africa, Live Cricket Score and Updates, 2nd Test Day 4: 1410 hrs IST: Mohammed Shami is struck for two boundaries in his first over of the day. Bumrah reduced South Africa to 3 for two in no time with the new ball.
South Africa would take special satisfaction out of a series win against India, especially if it came at SuperSport Park, due to their recent history against them. They stretched the lead easily by adding 141 runs for the third wicket.
Their run chase failed to get going and in deteriorating conditions, lost three wickets including the big wicket of Virat Kohli for 5. Shami's spell, in the morning, was merely an aberration to his series form.
Debutant Ngidi, who came on as first change, took a wicket with his first ball of the innings when Lokesh Rahul played a loose forcing shot off the back foot and was caught at backward point. But the variable bounce makes this one just as hard to bat on as the venomous ones of the past.
Why was the fifth bowler, Hardik Pandya, given an extended spell in the second session? R Ashwin, who opened the bowling, kept the close-in fielders interested but could not manage a wicket.
Even Keshav Maharaj has bowled only from the Pavilion End so far. "It's very disappointing because SuperSport Park usually prepares very good Test pitches and as day three, four and five roll on it proves to be very competitive". Bumrah benefited from it with the wickets of Aiden Markram and Hashim Amla, and Kagiso Rabada and Lungi Ngidi made full use of it too.
"It's massive for us, and massive for India as well, because they know he's not going out to bat".
Runs were a premium, which is why Elgar gruffed when it was pointed out that South Africa hadn't yet converted a half-century into a full house. The opening batsman brought his 9th Test fifty in style with an elegant cover drive for a four off Ishant Sharma. Though things did turn back for the visitors by the evening as a couple of run outs in the third session and good consistent bowling from R Ashwin saw the Indians claw back into the game.almost all the South Africa batsmen got starts, with only Dean Elgar (31) and AB de Villiers (20) failing to convert them into a big ones and Quinton de Kock getting out for a duck. If India were relieved to have seen the back of de Villiers, their joy doubled soon when another set batsman Dean Elgar (61, 121b, 8x4) picked up KL Rahul at deep backward square-leg. It was perhaps lack of experience that India didn't recognise how desperate the situation was in the afternoon.
Captain Kohli hit a masterly 153 in India´s first innings of 307 to stay in touch in Centurion, even though South Africa stretched a 28-run first-innings lead to 118 by scoring 90 for two in their second batting effort on a storm-shortened afternoon.
His first edge flew past Rohit Sharma at wide slip. Parthiv Patel missed a simple chance offered by Elgar (on 29 then), who edged behind off Jasprit Bumrah (2/30) in the 25th over. It was nearly a regulation first slip, and the wicketkeeper should have gone for the catch with his big gloves on. So there is a little frustration mentally but you need to be mentally strong at that stage and how long you can persist with it, that is more important.
Kohli was caught using words like "Shabaash Lambe" and "Sambhal Lambe" on the stump mic during their partnership together for the ninth wicket.
