Champions Australia have extended their unbeaten run in the T20 World Cup with a resounding 10-wicket win over Sri Lanka thanks largely to unbeaten fifties from the old firm of Alyssa Healy and Beth Mooney.
Grace Harris took 2-7 as well as a superb catch to get rid of Chamari Athapaththu off Ellyse Perry's bowling, which also played a big part in the win after Sri Lanka had started strongly in the powerplay at Gqeberha's St George's Park on Thursday.
The emphatic victory, which also featured four wickets for Megan Schutt, all but confirmed Australia's place in the semi-finals, with player of the match Healy's unbroken opening stand of 113 alongside Mooney making short work of their pursuit.
After Sri Lanka had been restricted to 8-112, Australia eased to the win with 4.1 overs to spare, Healy finishing 54no and Mooney 56no.
That Australia had put on only 37 in the powerplay was down to the Sri Lankan attack's discipline but hunting down a total so below par, it was only a matter of time before Healy and Mooney broke off the shackles.
The opening partnership reached 50 in the eighth over as Healy cracked a reverse-sweep off Inoka Ranaweera's left-arm spin, before she then came swinging through the line against medium pacer Achini Kulasuriya in the ninth over and smoked a straight six down the ground.
With 37 needed off 60 balls, Australia's chase had gathered an air of inevitability by the halfway mark.
Desperate to break the daunting opening stand, Athapaththu burned a review in the 12th over trying to get an lbw against Mooney overturned in Sri Lanka's favour.
The next over, Athapaththu dragged her length too short and bowled a two-bounce delivery.
Healy, on 46 at the time, made the most of the free hit that came off the no-ball. She reverse-slammed a short ball past point to reach her second fifty of the World Cup, off just 38 balls.
Mooney, too, brought up a half-century of her own not long after, reaching the milestone at a run-a-ball with a single towards long-off.
The winning single came off Healy's bat in the 16th over, the 32-year-old's innings coming off just 43 balls.
After Meg Lanning had earlier won her first toss of the tournament and sent Sri Lanka in, their openers carted a combined four boundaries in the first four overs.
Left-handers Athapaththu and Harshita Madhavi found fluency early and their powerplay score could have been higher than 1-38 had an airborne Harris not snaffled her superb diving catch running towards straight mid-off in the fifth over.
After breaking Sri Lanka's highest opening partnership against Australia in T20Is, a 12-run seventh over from Perry took Sri Lanka to 50 off 42 balls.
With their most destructive batter, Athapaththu, gone, it was little surprise that Sri Lanka's second 50 came at a much slower rate, off 60 balls.
Australia kept chipping away, using seven bowlers, though they appeared slightly tentative on the field at times. A missed stumping from Healy in Georgia Wareham's second over reprieved Madhavi when she was on 32.
Schutt's re-introduction at the death resulted in her dismissing Vishmi Gunaratne in the 18th over, and she took three more wickets in the final over to finish with striking figures of 4-24.
