brisbane heat 187 for 9 (G Harris 49, Redmayne 49, Mathews 3-30) beat Melbourne Renegades 181 (Glenn 4-23, Notts 3-33) by six runs
She and Georgia Prestwitz hit two fours each off Courtney Sippel in the final over, leaving the Renegades needing 23 runs off the last six balls.
Wareham sealed the victory by hitting fellow spinner Jess Jonassen for a six over deep midwicket. But when Jonassen had him caught and bowled on the next ball, the Renegades needed a miracle which did not occur.
English legspinner Glenn emerged as the best bowler for the Heat with figures of 5 for 55 on either side of the drinks break.
She took the crucial wicket of Kaur, who was the player of the tournament the last time she played for the Renegades, but missed a slog-sweep and was sent packing.
Earlier, the Heat’s openers took advantage of the batsman-friendly Junction Oval wicket and a fast outfield to give their team an equally good start.
But Wareham broke the opening partnership of 77 when Harris slogged Prestvige to deep midwicket.
Matthews took 2 for 2 soon after the drinks break and although the Heat never repeated their brilliant start, their total proved adequate.
