Darcie Brown claimed just the 6th hat-trick in WBBL history and the first for Adelaide Strikers but it wasn't enough to overcome Brisbane Heat in a rain-reduced 11-overs-a-side clash in Launceston.

Electrifying innings from Georgia Voll and Georgia Redmayne as well as some disciplined bowling from Heat held Strikers at bay despite a superb 54 from 30 balls from Laura Wolvaardt as Strikers fell just short chasing 105.

After all four matches were washed out on Saturday, the start of Sunday's morning match at Invermay Park was delayed by rain again. The match was reduced to 11 overs per side.

Heat got off to a blistering start thanks to Redmayne who smashed four fours and a six in her 14-ball 28. But she holed out to deep square off Brown off the third-last ball of the Powerplay with the total at 57. Ellie Johnston miscued the next ball to mid-on to make it two in two for Brown. That brought the dangerous Laura Kimmince to the crease for the hat-trick delivery. Brown bounced Kimmince first ball and she got a thick top edge trying to hook that carried all the way to deep fine leg where Wolvaardt held the catch to complete the hat-trick.

Heat kept the foot on the gas despite slumping to 4 for 57. Voll smashed 31 not out from 17 balls, including two sixes to lift the total to 5 for 104 from 11 overs.

Wolvaardt and Dane van Niekerk put on a 68-run opening stand in the chase but they were always behind the rate and the pressure eventually took its toll. Jess Jonassen took two wickets in two balls in the 8th over and Georgia Prestwidge did the same in the 10th. Strikers needed 18 from the final over but could only manage 12.
