Brisbane dominated the Scorchers, posting 5-162 and then dismantling the strong Perth batting line-up for just 103 in the 18th over to win by 59 runs and move into the top four for the first time.
The victory made it four times in a row that the Heat have beaten Perth on the bounce when they have met on a weekday, successfully chasing the Scorchers target on three occasions and tonight comfortably defending their total after losing the bat flip and being sent in.
Wicket-keeper Georgia Redmayne claimed player of the match honours in a crowded field, with a string of strong performances from the Heat as they claimed their first win of the tournament in their second and final game in Hobart.
Redmayne top-scored with 59 not out, as well as taking four catches and a stumping.
There were other multiple performers too, with allrounder Grace Harris hitting 34 from 30 balls as she and Redmayne put on 68 in 7.5 overs, and then taking 3-16 from 3.2 overs.
Captain Jess Jonassen had an impact, with 1-14 from three overs and 19 not out from six balls that included four consecutive fours off Devine’s final over that went for 19 runs.
Indian spinner Poonam Yadav did a sterling job on the way to 2-15 from four overs, taking wickets and shutting down any chance of a Perth lower order fightback.
Pace bowler Nic Hancock bowled with pace and variation to knock over batting trumps Beth Mooney and Sophie Devine on the way to fine figures of 3-19 from three overs.
The Heat will now travel to Launceston for their next block of games which will include clashes with the Melbourne Stars on Saturday followed by the Adelaide Strikers on Sunday.
