The copybook stroke
South Africa's batsmen struggled to time the ball in the first couple of hours after deciding to bat first and there weren't many attacking shots. In the sixth over, Faf du Plessis got his first boundary with a masterful on-drive. Mashrafe Mortaza pitched the ball right up to his bat and du Plessis simply brought his bat down as if in a tutorial video. The ball connected right on cue and mid-on could hardly move an inch.

The retreat
As Hashim Amla followed through after punching a boundary in the seventh over, he came close to bumping into Mustafizur Rahman, who had just finished his follow-through. Mustafizur was looking down but swiftly moved his left foot out of the way although the batsman was still some distance from him. The change of direction was perhaps a lesson from his collision with MS Dhoni, which had resulted in a fine for the bowler and a lot of controversy.

The specialty
Mustafizur got JP Duminy with his specialty off cutter as the batsman chipped straight to cover in the 32nd over. The delivery was even more effective when he got one to cut back at Kagiso Rabada who prodded forward to defend the ball but it went through him and struck the middle-stump. The turn on the ball would have made any left-arm spinner happy, especially as it went past a left-handed batsman's defensive push.

The twirl
Soumya Sarkar was peppered with the short ball and every time it was within his reach, he went for the pull shot. He timed only a few of them with the ball mostly dropping short of mid-off. But when it was pitched up, he unfurled his wrists. In the 13th over, Chris Morris pitched the ball up to him and immediately saw it fly through midwicket as Soumya went on the whip. It was a no-ball too and Soumya got boundaries off the next two balls. Bangladesh were well on their way.

The miscommunication triangle
Soumya top-edged a slog against Farhaan Behardien in the 21st over and the ball went high enough for three fielders to converge under it. Faf du Plessis came from short third-man, Kagiso Rabada from short fine-leg and the wicketkeeper Quinton de Kock ran back from his position. De Kock never got close but it was the miscommunication between du Plessis and Rabada that ultimately cost South Africa a wicket. Du Plessis pulled out at the last second and Soumya survived.
