MELBOURNE, Australia (CMC) - Captain Hayley Matthews registered her third-straight, single-digit score as Melbourne Renegades extended their wretched run with a chastening 10-wicket defeat to Perth Scorchers.

Renegades rallied to 133 for five off their 20 overs after being sent in at Junction Oval here Saturday and then watched helplessly as Scorchers raced to their target in the 12th over, with captain and opener Sophie Devine belting an unbeaten 70 off 36 deliveries.

The defeat was their seventh straight in nine outings and eighth of the campaign, leaving them rock bottom of the Women's Big Bash League on two points.

Matthews managed only eight at the top order and now has 107 runs from nine innings, at an average of just under 12.

Her highest score this season was 31 in the first clash with Scorchers earlier this month but the knock remains the only time she has passed 20.

Georgia Wareham top-scored with an unbeaten 57 off 46 balls with five fours and a six, anchoring a 62-run, unbroken sixth-wicket stand with Josephine Dooley (14 not out), to pull Renegades around from 71 for five in the 13th over.

Matthews, her side's leading wicket-taker with 10 wickets, then came up empty handed as Devine and Beth Mooney, who struck 47 not out off 32 balls, inflicted further woes on Renegades in a punishing opening stand.

Devine counted two fours and eight sixes while Mooney struck nine fours.
