Brisbane Heat 1 for 180 (Redmayne 98*, G Harris 65) beat Melbourne Renegades 6 for 159 by 21 runs

Brisbane Heat openers Georgia Redmayne and Grace Harris have set a franchise-record opening stand to set up a 21-run win in the WBBL clash with the Melbourne Renegades.

Redmayne and Harris combined for a stunning 165-run stand in Mackay that featured scintillating shots all around the ground and slick running between wickets. The partnership was the highest for any wicket in the Heat's history and the third-best in WBBL history.

Heat have a strong record against the Renegades and their 180 total was the fourth best in their history, with three of those coming against their Melbourne opponents.

The powerful Harris gave the innings early impetus with three boundaries in the opening over. Redmayne, a stylish left-hander, started sedately but warmed to her task. Her timing and placement throughout the innings was impeccable. She started the final over within reach of a century but was at the non-striker's end for the final two deliveries.

Renegades began their innings with a flourish, opener Hayley Matthews racing to 35 from 19 deliveries. She was looking dangerous before Harris flung herself to the left to take a splendid diving catch in the covers.

The required run rate blew out to over 12 with six overs remaining and the Heat cruised to their second win in a row. Impressive legspinner Amelia Kerr was the pick of the Heat bowlers.
