Having made a World Cup record chase to reel in India’s 277 for seven in Auckland on Saturday, undefeated Australia made light work of South Africa's 271 for five, ticking off the winning runs with nearly five overs to spare.
Lanning smashed 135 off 130 balls as Australia won its sixth straight match, the star skipper scooping another player-of-the-match award after hammering 97 against India.
"We thought (270) was par and the track got better towards the end of South African innings," Lanning said.
"It was a new wicket, so the longer the sun beat on it, the better it got."
As did Lanning.
Australia lost openers Rachael Haynes (17) and Alyssa Healy (5) cheaply but Lanning steadied the ship before going on the offensive in partnerships with Beth Mooney (21) and Tahlia McGrath (32).
Unbeaten coming into the match, Sune Luus’s South Africa was buoyed by 90 runs from opener Laura Wolvaardt but rued a dreadful day in the field.
It blew a chance to dismiss Lanning for seven when wicketkeeper Trisha Chetty failed to dive for an edge.
McGrath and Ashleigh Gardener (22) were also reprieved as a slew of catches went to grass.
Australia was much sharper, as shown by Gardner, who flew backwards for a stunning one-handed catch on the boundary to dismiss Mignon Du Preez for 14.
"We will discuss it after the game and won’t repeat it."
Australia has now won 18 successive matches when chasing in ODIs.
Already qualified for the semifinals, it heads into its final group match against Bangladesh on Friday with only one concern, a back injury for Ellyse Perry that saw the all-rounder spared her usual top order batting.
South Africa plays India on Sunday.
- In the second game yesterday, played in Hamilton, India trounced Bangladesh by 110 runs.
Yastika Bhatia, the player of the match, top-scored in India’s tally of 229 for seven.
Bangladesh was all out for 119 after only 40.3 overs.
- Poor weather ruined any chance of play between Otago and Wellington in a Plunket Shield match at the University Oval yesterday.
