Super Over Perth Scorchers 0 for 14 beat Brisbane Heat 2 for 12

Sophie Devine struck two Super Over sixes as Perth Scorchers secured a come-from-behind victory over Brisbane Heat who will be left wondering how the game slipped away from them.

Heat needed 51 off 62 balls with nine wickets in hand in the latter part of their chase having been set up by Grace Harris. But in the end, they were fortunate to scrape into the Super Over when Lilly Mills, who took 3 for 28, couldn't gather the final ball of the innings at the stumps to make a run-out with the pressure telling on both sides.

South Africa allrounder Anneke Bosch then struck two boundaries off Marizanne Kapp to leave Scorchers needing 13. Devine ended up doing it with two balls to spare against Jess Jonassen who sent down a huge full toss first delivery.

Heat lost their composure badly in the chase, having reached 1 for 87 in the tenth over. Spinners Mills and Alana King, both playing their first matches for Scorchers, combined to take five wickets while Heather Graham went for just two in the penultimate over.

King, who moved from Melbourne Stars, took a brilliant caught-and-bowled to remove the dangerous Laura Kimmince while Mills responded strongly after the first ball of the final over had gone for four.

Earlier in the chase, Kapp had claimed the vital wicket of Harris, lbw trying to pull a delivery that was too full, after she had dominated the early stages. The scrambled thinking of Heat was summed up in the final over when Nadine de Klerk wandered out of her crease having completed a single and was run out.

Scorchers had made a good start before Jonassen, in her first game back from injury, claimed Devine first ball. Beth Mooney anchored the innings but the rest of the order could not get going as they lost 4 for 30 in 7.2 overs. India legpsinner Poonam Yadav claimed Mooney as her first WBBL wicket.
