Uncool running
It was the fourth match of the series but Virat Kohli and Shikhar Dhawan had still not learnt read each other's body language. After Kohli drove Kagiso Rabada to mid-off, he called for a run and set off but Dhawan did not want it and remained rooted to his crease. Kohli was almost halfway down the track and had no choice but to turn back. Luckily, this time it was not costly as the mid-off fielder had to make some ground to stop the ball and may not have been as alert to the pair's penchant for miscommunication. No damage done but as Graeme Smith suggested while commentating, the pair may want to share a meal and chat about how best to run between the wickets.
Cool running
That scare did not put Kohli off chancing the arm again, when he was on 49 no less. He pushed the ball, this time delivered by Chris Morris, into exactly the same mid-off region and set off again. He had Ajinkya Rahane at the other end, who was attuned to Kohli's quickness and responded with the same enthusiasm. But Kohli was taking on AB de Villiers. He realised the urgency of the situation and had to put in a dive to ensure he made his ground, but de Villiers missed anyway so Kohli was safe. He thumbed his chest in celebration of his half-century and his small victory over the South African captain.
The guns
Kohli had been firing all innings so when he sent Aaron Phangiso over Dale Steyn's head at long-on and the boundary for the six that brought up his century, he had to bring out the guns that got him there. In celebration, Kohli flexed his biceps, one at a time, in the direction of the Indian change-room. It seemed more a gesture of irony, than a symbol of strength, but after the shot Kohli had struck, they were his to show off as he pleased.
The blow
India's batsmen were not the only ones who suffered from poor communication. De Villiers and Faf du Plessis, South Africa's oldest friends, had an awkward moment when de Villiers slammed a Harbhajan Singh delivery down the pitch, intending to hit it down the ground but striking his team-mate instead. Du Plessis was trying to take evasive action and was turning his back on the shot, was hit flush on the elbow. He was in obvious pain, went down immediately and could not flex the arm at the elbow joint for a few minutes. He eventually received treatment and was able to continue.
Runaway ball
Things were getting tough in the middle of the South Africa innings when de Villiers decided he had to try and dominate the spin, and charged at Amit Mishra. He was well out of his crease as he looked to flick the ball on the leg side but missed and would have been out had MS Dhoni not missed as well. Dhoni could not catch the ball as it went down the leg side but had protection with Suresh Raina at short fine leg. Raina gathered the ball cleanly and had a shy at the stumps but his effort was wild and he missed too, allowing de Villiers to get back in time.
Runaway batsman
Chris Morris was catching his breath after Mohit Sharma's lbw appeal against him was turned down, but he should have been looking down the other end of the pitch, where de Villiers saw an opportunity to steal strike. By the time Morris saw his captain, de Villiers was almost at the same end of the strip and had his arms in the air as if to reprimand Morris for not responding. Morris eventually got a move on but was never going to make his ground. Ajinkya Rahane had more than enough time for a direct hit at the non-striker's end and struck on target.
