Adelaide Strikers captain Tahlia McGrath won the bat flip and sent the Heat into bat first on an overcast evening in Adelaide.
The home team kept the Heat to 1-25 at the end of the powerplay, Strikers young gun Darcie Brown (2-18) taking the breakthrough wicket of opener Georgia Redmayne (1).
Strikers veteran Amanda-Jade Wellington (5-8) kick started the Heat’s domino of wickets, her first being big-hitter Grace Harris (17), then Georgia Voll (20), Mikayla Hinkley (0), Jess Jonassen (1) and Laura Kimmence (3).
A miraculous cameo partnership between Nicola Hancock (40) and an injured Nadine De Klerk (18*) helped the Heat set their rivals a 114 run chase.
Heat fans saw a glimmer of hope in quick Nicola Hancock as she removed the dangerous South African opener Dane van Niekerk for 12.
But the Strikers superstar Katie Mack (50*) proved too good against the Heat’s bowling attack as she continued her outstanding run at the top of the order, smacking her fifth half-century in the WBBL tournament.
Mack’s handy partnership with her captain McGrath (38*) saw the two ease their team to a victory by eight wickets with 3 overs to spare.
Tonight’s win sees the Strikers return to their home ground tomorrow night at 6.10pm AEST, where they meet the Melbourne Renegades in the Challenger.
The winner of tomorrow’s Challenger will play top-ranked Perth Scorchers in the Final at Optus Stadium on Saturday 27 November at 6.10pm AEST.
