Georgia Wareham's best Big Bash figures and Courtney Webb's 34 not out led the Renegades to victory in the opening game of WBBL|11.
MATCH REPORT: Combined efforts oust Heat in soggy season opener
Melbourne Renegades have repeated last season's WBBL final win over Brisbane Heat in a seven-wicket win impacted by rain at Allan Border Field.
Renegades' stand-in captain Georgia Wareham has returned career-best Big Bash figures in a seven-wicket win over Brisbane Heat in the rain-shortened Weber WBBL|11 season opener.
Wareham, filling in for injured skipper Sophie Molineux, took 3-12 in a superb spell of leg-spin in the rematch of last season's WBBL final, also won by the Renegades.
She was also there at the end with the bat to guide her side to victory.
The Heat, batting through light drizzle at Allan Border Field on Sunday afternoon, were bowled out for 133 off the last ball of the 20th over after being sent in by Wareham.
The rain strengthened and when play resumed the run chase was reduced to eight overs with a DLS target of 66.
The Renegades were 3-13 after two overs but Wareham (16 not out) and in-form Courtney Webb (34no) guided them to victory with three deliveries remaining.
India's Jemimah Rodrigues and Nadine de Klerk of South Africa - opponents in the recent World Cup final won by India - teamed up again for Brisbane.
Rodrigues, who had made an unbeaten 127 in India's stunning semi-final win over Australia, made just six. De Klerk (40 off 38) was in top form and struck the ball beautifully through the cover region.
West Indies allrounder Chinelle Henry quickly endeared herself to the home crowd with a swashbuckling 29, which featured one huge six.
Georgia Redmayne, usually an opener for the Heat where she has enjoyed so much success, was wasted batting at No.8 and looked good for her 16 before she too fell to spin.
Wareham rotated her bowlers superbly with fellow spinner Alice Capsey (3-22) and seamer Tess Flintoff (3-30) shining.
