Perth Scorchers 142 for 8 (Mooney 77) beats Brisbane heat 114 (L Harris 40, King 5-16) by 28 runs
Mooney rescued his team after a mid-innings collapse left them in a precarious position at 106 for 6 in the 17th over.
But the end came quickly after King caught Harris at long range. It was the first of three wickets in five balls, with just one run added, as the Heat were dismissed for 114 with two overs remaining. King took the last four wickets and returned his best WBBL figures.
Scorchers improved to 2-1 and Heat fell to 2-2.
The Scorchers were fairly well placed at 81 for 2 in the 12th over but lost 4 for 15 before Mooney boosted his side with some effective late hitting. She looked lost in the first over, bowling and missing three times against the impressive Indian quick Shikha Pandey.
Mooney put 40 in a starting position with Sophie Devine. Devine hit some nice offside boundaries before being attacked by Nadine de Klerk.
Nicola Hancock induced two batsmen to mistime a short ball and catch it easily.
Mooney hit just three fours in his first 40 runs of steady accumulation, but he accelerated and accelerated in the last three overs. The prolific left-hander hit five of her nine fours in that period as the Heat piled up 34 runs in the last three, before Hancock bowled it behind her legs on the last ball of the innings.
Mooney appeared to injure a finger and handed the gloves to England goalkeeper Amy Jones midway through the Heat’s innings.
Heat lost both their openers in the powerplay and fell to 38 for 3 in the sixth over, despite a typically belligerent start from opener Grace Harris.
They looked out of contention at 87 for 7 after 15 overs, but Laura Harris made them sweat before King’s final over proved decisive.
