South Africa 229 for 6 (Kapp 75, Bosch 44) beat Australia 149 (Garth 42*, Kapp 3-12) by 84 runs (DLS method)

She then tore through Australia's top order and finished with 3 for 12. Under lights, and on a surface freshened by steady drizzle that fell for much of the afternoon, Australia's batting was then blown away in a manner rarely seen as they sank to 71 for 8.

Kapp had Alyssa Healy caught behind driving and produced a wicked inswinger to snake past Beth Mooney's inside edge. She then trapped Phoebe Litchfield lbw to leave Australia 34 for 3 while Ashleigh Gardner was carrying a hamstring injury sustained in the field.

Australia were far from at their best in the field with a total of five dropped chances, including Kapp on 37 and 45 - the latter a regulation low edge to Healy. Only one partnership - between Bosch and Tazmin Brits - passed fifty but there were five middle-order efforts of between 31 and 46 which kept South Africa moving.

Australia had made the ideal start by removing the key wicket of Laura Wolvaardt when she edged Megan Schutt to slip for a duck. There was nearly a second wicket in the opening over but Mooney couldn't quite haul in an edge from Bosch who was then dropped on 1 by Perry at long leg.

South Africa were cautious through the powerplay, reaching 32 for 1 after 10 overs, and at one stage during the early stages Australia had four slips. But the visitors started to move through the gears, with a helping hand from the fielding, although when Sune Luus was well caught at long-on by Sutherland they were an uncertain 117 for 4.

Kapp, however, found important partners in de Klerk and Tryon, bringing up her fifty from 62 balls after a second rain delay. She was frustrated at finding cover off a Schutt full toss in the 42nd over, but Tryon ensured a strong finish by taking 18 off the penultimate over.

There was a curious incident towards the end of South Africa's innings when Australia were unable to review an lbw appeal against Tryon, on 15 at the time, because the big screen had already shown a replay.
