Three wickets from Poonam Yadav and a half-century from Georgia Redmayne has guided Brisbane Heat to a comfortable win over Sydney Thunder at the Adelaide Oval.

Poonam bowled beautifully snaring 3 for 17 including the crucial scalp of India team-mate Smriti Mandhana to help restrict Thunder to 7 for 143 before Redmayne made her third half-century of this WBBL to lay the foundation for the chase, with Georgia Voll, Mikayla Hinkley and Laura Kimmince producing some powerful striking to finish the job with 10 balls to spare.

Thunder looked on track to set an imposing total racing to 1 for 62 in seven overs with Mandhana striking six fours and a six in her 37. But she holed out to deep square leg in Poonam's first over. Corinne Hall was trapped lbw next ball and Thunder fell in a hole. Phoebe Litchfield held the innings together with a composed 40 from 32 balls but became Poonam's third victim in the 14th over. It was left to captain Hannah Darlington to push the total up to 143 with a handy 19 from 15 balls at the death.

Redmayne continued her good form guiding the chase after the early loss of Grace Harris. Redmayne struck seven fours in her 57 from 45 balls. She shared a 41-run stand with Voll and a 59-run stand with Hinkley to get the equation under a run a ball before she fell to Deepti Sharma with 22 runs to win. Kimmince whacked a six and a four to ice the game. Darlington picked up two consolation wickets late to finish with figures of 3 for 21.
