Perth Scorchers 160 for 6 (Devine 37) beat Sydney Thunder 159 for 5 (Knight 71, Learoyd 53) by four wickets
Half-centuries from Heather Knight and Anika Learoyd were in vain as Perth Scorchers continued their unbeaten start to the WBBL season with a four-wicket victory over the Sydney Thunder in Perth.
Knight pummelled 71 from 46 balls and Learoyd (53 off 44) also produced the goods as the visitors posted 159 for 5 at the WACA Ground on Wednesday.
Scorchers, despite being without injured captain Beth Mooney (quad tightness), reached the victory target with nine balls to spare, improving their season record to a perfect 5-0. The Thunder slipped to 2-3.
There was no standout innings from the home side, but the work of Sophie Devine, Katie Mack, Mikayla Hinkley, Chloe Piparo and Chloe Ainsworth ensured Scorchers got over the line.
After winning the bat flip and electing to bat, Thunder stumbled to 18 for 2 before Knight and Learoyd turned their fortunes around.
Knight thumped 12 boundaries and Learoyd cracked five fours and a six as the pair combined for a 128-run partnership.
Pakistan international Fatima Sana was the most economical Scorchers bowler with 1 for 26 off four overs, while spinner Alana King and Ainsworth were also key contributors.
Perth were cruising at 86 for 1 in the 10th over in their run chase. But when Devine was bowled by Nadine de Klerk and Mack hit a Jemma Barsby full toss straight back to the bowler in the space of seven balls, a few wobbles set in.
Hinkley's disastrous run-out and Sana's second-ball duck reduced Scorchers to 133 for 6, with the team still needing 27 runs for victory off 27 balls.
Piparo and Ainsworth held their cool to get them over the line, with Scorchers (5-0) and Sydney Sixers (4-0) the only unbeaten teams this season.
