Katie Mack's finest hour as a WBBL player has helped Adelaide into the competition's top four with an eight-wicket win over the Sydney Sixers.
On the same day Perth plunged the Melbourne Stars' finals hopes into danger, Mack put on a masterclass to breathe life into the Strikers' campaign.
Chasing the Sixers' 4-142, Mack's unbeaten 67 from 55 balls helped the Strikers pull off the third biggest chase in their history.
Mack's score was the highest of her WBBL career and the highest of any Strikers player this summer.
After Adelaide fell to 1-5 early, the Sydney junior took charge in an innings that included eight boundaries with the majority coming through the covers.
Tahlia McGrath also found her form again with an unbeaten 40 as the Strikers leapfrogged the Sixers into the four.
The competition's glamour franchise - the Sixers - are now at risk of missing the finals for the third straight year.
Wednesday's loss leaves them fifth on nine points alongside the Strikers but with a worse-off net run-rate and having played 10 games to their nine.
They looked to be on top early when Ellyse Perry took 10 runs off two Darcie Brown balls, but the match swung when she was run out next delivery.
Ash Gardner then fell for a golden duck to a ball from Brown that nipped back, leaving Shafali Verma (53no from 43) and Nicole Bolton (34 from 38) to rebuild.
Last year's grand-finalists the Melbourne Stars are also at risk of missing the finals after being torched by the Scorchers.
They, too, sit on nine points but are sixth with a poor net run-rate and have played one additional game on the Sixers and two more than the Scorchers.
They have just three games left which are essentially must-win, after winning just four of their 11 so far.
Perth's domination didn't help the Stars' plight as the Scorchers pulled off the equal-second quickest chase in WBBL history.
After constant wickets kept the Stars to 9-97 from their 20 overs, the Scorchers chased it down in 10.5 overs.
It also marked just the ninth 10-wicket win in the seven-year history of the competition, as Beth Mooney (57 from 38) and Sophie Devine (35 from 27) got the job done without loss.
The result put the Scorchers in second, looking safe of a finals spot with a four-point gap between Brisbane in third and Adelaide in fourth.
