With a howling gale whistling behind her, Shabnim Ismail, one of the fastest bowlers in women's cricket, blew away West Indies' top order, but South Africa lost 9 for 28 in pursuit of 108 to be dismissed for 76. The 31-run win took the defending champions to the top of the Group A points table and a step closer to the semi-finals.

West Indies captain Stafanie Taylor, one of Ismail's three wickets, overcome a neck injury and claimed a career-best 4 for 12 to tear up South Africa's middle and lower order. She was backed up by electric fielding, highlighted by Deandra Dottin's direct-hit to run out Dane van Niekerk for 1. Dottin swooped in from point, collected the ball, threw down the stumps - all in one swift motion - to have Darren Sammy grooving in the stands at a ground that has been named after him. The night ended in similar revelry, with the West Indies women jiving with a packed crowd in Gros Islet.

South Africa had a strong chance to secure their first win over West Indies in the World T20 after limiting the hosts to 107 for 7. They were still the favourites when opener Lizelle Lee and No. 3 Marizanne Kapp put on a 31-run stand after weathering incisive new-ball bursts from Shakera Selman and Shamilia Connell.

A spectacular collapse, though, was then set in motion, when Dottin had Lee holing out to sweeper cover, where Britney Cooper pulled off an outstanding catch in the 11th over. In the next over, Dottin capitalised on a mix-up between van Niekerk and her life partner Kapp, and caught the South Africa captain well short. Taylor's loopy offspin and two further run-outs hastened the end for South Africa. From 48 for 1, they crashed to 76 all out, which left van Niekerk short of words at the post-match presentation.

In the early exchanges, it was Ismail, who had silenced the West Indies top order and the crowd. She struck with her fourth ball, having Hayley Matthews nicking off to slip via a deflection off the wicketkeeper. She then hit the deck with her next ball and removed Taylor for a golden duck. Then, when she had Dottin popping a catch to extra cover in her next over, West Indies were 22 for 3 in four overs.

Moseline Daniels snuck through the weak defences of Shemaine Campbelle in her first over to reduce West Indies to 29 for 4, but Natasha McLean and Kycia Knight staged a recovery with a 45-run partnership, the highest in the match. McLean was quite fluent through the off side, caressing Masabata Klass for fours through covers and mid-off. Knight switched gears only after McLean holed out in the 15th over, hoisting Daniels for a four and a six in the 18th.

Knight herself holed out in the next over, but tigerish bowling and fielding from West Indies made their total of 107 for 7 look a whole lot bigger.
