After being sent into bat by the Strikers this morning, the Scorchers couldn’t gather enough momentum with the bat and posted 115 runs from their 20 overs.
Nicole Bolton was solid at the crease and crafted a patient knock of 41 runs to anchor the innings.
Nat Sciver (26) provided some good support early, before she was out caught in the tenth over.
Irish import Kim Gath (2-25) gave Perth the ideal start and claimed two wickets inside her first two overs, which left Adelaide at 3-22 in the third over.
Piepa Cleary snatched the other wicket, removing New Zealand international Sophie Devine for a golden duck.
From there, the Strikers never looked back and chased down the total with more than five overs to spare at Brisbane's Allan Border Field.
The Scorchers head home this afternoon in seventh place on the WBBL adder with one win and two losses.
The iconic WACA Ground will host the next WBBL Big Weekend, with the Scorchers hosting the Melbourne Renegades on Friday 1 November and then the Melbourne Stars on Saturday 2 November.
