Looking to atone for Sunday’s Melbourne Derby loss to the Renegades, skipper Meg Lanning won the toss and elected to bat.
Despite a solid start from Elyse Villani (16), the Stars’ top order struggled, falling 4-24 when Villani was bowled by former Star Alana King shortly after the powerplay.
Kim Garth (31) held the innings together with another superb outing, while late contributions from Tess Flintoff (14), Sophie Day (10*) and Rhys McKenna (8*) ensured the Stars scraped to a total of 9-97 off their 20 overs.
Looking to defend the total with their bowling performance, the Stars’ strong attack was unsuccessful against the world-class opening duo of Beth Mooney and Sophie Devine.
Both Linsey Smith (0-11) and Kim Garth (0-25) attempted to force a breakthrough that could shift the momentum but were powerless in stopping the Scorchers from romping to a 10-wicket victory.
The Stars next play on Thursday afternoon as they take on the Melbourne Renegades at Karen Rolton Oval.
Perth Scorchers 0-98 (10.5) defeated Melbourne Stars 9-97 (20).
