A superb bowling performance by the Proteas saw them bowl Bangladesh out for just 84 and, although their batsmen had some troubles of their own on a spiteful pitch, they managed to cross the line with six wickets and 39 balls to spare at the T20 World Cup in Abu Dhabi on Tuesday.
Bangladesh, having been sent in to bat, were thoroughly undermined by fiery fast bowling at its best by Kagiso Rabada and Anrich Nortje.
Rabada began the rout in the fourth over when he had Mohammad Naim (9) caught at a wide mid-on and then trapped Soumya Sarkar lbw first ball with a brilliant late inswinging yorker.
In Rabada’s next over, Mushfiqur Rahim (0) was superbly caught by a juggling Reeza Hendricks at slip, South Africa’s pace spearhead finishing with career-best figures of 3/20 in this format.
There was no respite for Bangladesh as Nortje continued his outstanding tournament, bouncing out Mahmudullah (3) and then returning to wrap up the innings with two wickets in two balls as he finished with 3/8 in 3.2 overs.
In between, spinner Tabraiz Shamsi did his usual fine job in the middle overs with 2/21 in his four overs.
Opener Liton Das (24 off 36) and Mehedi Hasan (27 off 25) were the only Bangladesh batsmen to contribute much.
Paceman Taskin Ahmed (4-0-18-2) made it anything but easy for the South African top-order as he jagged a delivery back into Hendricks (4) to trap him lbw and then a fine ball that held its line had Aiden Markram (0) well-taken at slip by Naim.
Quinton de Kock looked promising for his 16 but then missed a straight one from spinner Mehedi, to leave the Proteas in trouble on 33/3.
But captain Temba Bavuma was unflustered and batted through to the end with his 31 not out off 28 balls including some great strokeplay that brought him three fours and a six.
Rassie van der Dussen (22) also helped weather the early storm before Shoriful Islam took a fine outfield catch off spinner Nasum Ahmed.
Perhaps the most important thing to come out of the match was the boost to the Proteas’ nett run-rate as they won in the 14th over, taking their run-rate to +0.74, stretching their lead over Australia’s -0.63.
The win solidified the Proteas’ position of second in the group, behind England, who they face in their final round-robin match on Saturday.
