Brisbane Heat 187 for 9 (G Harris 49, Redmayne 49, Matthews 3-30) beat Melbourne Renegades 181 (Glenn 4-23, Knott 3-33) by six runs

She and Georgia Prestwidge each belted Courtney Sippel for two fours in the penultimate over, leaving Renegades requiring 23 runs from the last six deliveries.

Wareham blasted fellow spinner Jess Jonassen for six over deep midwicket to put a stunning win within reach. But when Jonassen caught and bowled her from the next delivery, Renegades needed a miracle that did not transpire.

English legspinner Glenn inspired a collapse of 5 for 55 either side of the drinks break and emerged as the pick of the bowlers for Heat.

She took the crucial wicket of Kaur, who was player of the tournament the last time she appeared for Renegades but mistimed a slog-sweep and was sent packing.

Earlier, Heat's openers had their side off to a similarly flying start, taking advantage of the batter-friendly Junction Oval wicket and fast outfield.

But Wareham broke the 77-run opening partnership when Harris slogged her to Prestwidge at deep midwicket.

Matthews took 2 for 2 just after the drinks break and though Heat never quite replicated their prolific start, their total proved enough.
