Rachael Haynes hit a classy fifty to help defending champions Australia overcome a fighting Sri Lanka by five wickets in their second Group A match.
Chamari Athapaththu (50 off 38 balls) struck a quick half-century but Nicola Carey (2/18), who missed the India game, and Molly Strano (2/23) helped Australia restrict Sri Lanka to a modest 122 for six.
Chasing the target, the Australian hearts were racing when Alyssa Healy, Ashleigh Gardner and Beth Mooney — all fell within four overs before Haynes and captain Meg Lanning (41 not out) stitched a 95-run fourth-wicket stand to take the hosts out of trouble.
