Meg Lanning produced another masterclass, smashing an unbeaten 135 as six-time champions Australia continued their invincible run with a five-wicket thrashing of South Africa in the ICC Women's World Cup here on Tuesday. Lanning scored her 15th ODI century with 15 hits to the fence and one maximum during her 130-ball unconquered innings to help Australia successfully chase down South Africa's total of 271 for 5 with 28 balls to spare at Basin Reserve. Invited to bat, opener Laura Wolvaardt cracked a 134-ball 90, while skipper Sune Luus (52) notched another half-century as South Africa posted a decent total from their 50 overs. However, it proved inadequate in the end as Lanning took control of Australia's chase and recorded her third World Cup century to lead her team to a comfortable victory. The win further consolidated Australia's position at the top of the table with 12 points from six matches and they are likely to end at the top with just one match to go against Bangladesh in the league stage.
