After being sent into bat, The Stars’ 9-177 was their highest ever WBBL total, led by a lethal Meg Lanning innings as the captain pounded 54 from just 25 balls.
It was the skipper’s third half-century in a row and included six fours and three sixes.
Elyse Villani wasted no time in an eventful first over, striking two boundaries in the match’s first three balls, before Meg Lanning survived an early run-out scare.
The skipper followed suit with a trio of her own boundaries in the second over, setting the tone for a destructive powerplay as the pair generated 68 runs without loss in the first six overs.
Remarkably, Lanning scored 54 of these in a fiery power-hitting display.
But the captain’s volcanic knock was soon cut short, bowled by Heat spinner Amelia Kerr in the seventh over.
The ninth over saw Villani (25 off 22) also dismissed by Kerr, trapped in front of the stumps for LBW.
South African import Mignon du Preez looked in form early in her innings, but an ambitious attempt to come back for a second run saw her run out for 12 off 10 balls.
Young gun Annabel Sutherland looked to steady the ship with Erin Osborne, with a well-made 23 from 20 — including an impressive straight drive for six — coming to an end when the 19-year-old was caught on the boundary.
Osborne was caught behind for 20 off 17, before Alana King’s fiery cameo (17 off 8) helped propel the Stars to their highest ever total.
In reply, the Heat were off to a patient start before Holly Ferling broke the opening partnership in the sixth over, then illustrated her athleticism with a breathtaking run-out.
Three more wickets soon followed as the Heat lost 5-15 within four overs, effectively sealing a fourth straight Stars triumph.
Alana King claimed 2-22 from four overs, while Ferling, Sutherland, and Sophie Day all took one wicket apiece as the bowling unit held off Grace Harris’ unbeaten 81.
The Stars will look to keep their undefeated record intact when they face the Strikers on Tuesday afternoon.
