Watch: Mohammad Siraj steps on boundary rope after catch, Deepak Chahar is not amused

It can drive any bowler mad. And cause a captain to fly off the handle.

It was the last over of the South African innings. Deepak Chahar was the bowler and David Miller was trying to hit everything out of the park. David Miller swung the fourth ball of the over, a high full toss which was called a no ball, over square leg for a super massive six. The free-hit ball was dispatched over deep midwicket for another maximum.

Miller pulled the next ball from outside the off stump and as it went high up in that in the midwicket region it looked for a second that Mohammad Siraj had it under control just with the boundary rope.

"Taken on the boundary," shouted the commentator, and the camera zoomed in to show Siraj with his right foot touching the rope. Not out; and six conceded. Slo-mo replays showed that Siraj, while backpedalling for the catch did have enough space to end up well inside the rope.

Cameras caught Chahar in the middle of delivering a torrent of something not so polite. Skipper Rohit Sharma held his hands together as if in prayer. Siraj grinned sheepishly like a schoolboy.

South Africa, powered by Rilee Rossouw's 100 of 48 balls finished with a huge 227 for 3, with all the four Indian pacers - Mohammad Siraj, Deepak Chahar, Umesh Yadav and Harshal Patel - giving in excess of 11 runs an over.

The performance of the pacers aggravated concerns about the quality of bowling in the death overs, especially now with Jasprit Bumrah out with a back injury.

India, playing with a batter short, never really looked in the chase after the early dismissals of Rohit Sharma and Shreyas Iyer and ended 49 runs short.

With the consolation win in the third T20I, SA prevented a whitewash and the series ended 2-1 in favour of India.
