Amanda-Jade Wellington bowled a superb Super Over and Sophie Devine's outstanding tournament continued in a thrilling victory for the Adelaide Strikers over the Sydney Thunder in Hobart. Devine top-scored in the main contest with 88 off 56 balls, taking her top of the run-scoring table, before striking the first ball of the Super Over chase to the boundary to ensure chasing seven to win was not an issue. Wellington, who took 3 for 17, had done superbly to keep the Thunder to six in their over after Sarah Coyte had trapped Nida Dar lbw with the final ball of the initial contest following two last-over boundaries from Rachel Trenaman which left the Thunder needing four off three. The Thunder had been well on track in the chase after an opening stand of 59 in 5.2 overs by Rachel Priest and Naomi Stalenberg but the game changed in the hands of Wellington who remove Priest, Alex Blackwell and Phoebe Litchfield.

A masterclass from Australia captain Meg Lanning helped the Perth Scorchers sweep the Sydney Sixers in back-to-back matches at Lilac Hill and all but secure a semi-final berth. Chasing 165, Lanning ripped the game away from the Sixers scoring 81 from 50 balls and shared a 104-run opening stand with Amy Jones in less than 13 overs. She fell with 19 still needed from 15 balls, but Nat Sciver continued her good form making 39 not out from 22 balls to guide the side home with four balls to spare and eight wickets in hand. Earlier, Sciver made the big breakthrough with the ball removing Alyssa Healy with the first ball of the match. Healy top-edged a pull shot back to Sciver who claimed her for the second time in two days. Erin Burns and Ash Gardner both made half-centuries, with Burns batting through the innings to finish on 60 not out. But Dane van Niekerk was the only Sixers batter to strike above 133 in their total of 6 for 164 and there semi-final prospects are in the balance.

Sarah Coyte held her nerve in the face of a thrilling onslaught from Chloe Tryon as the Adelaide Strikers clung on for a two-run win against the Hobart Hurricanes to book a place in the semi-finals. The Hurricanes were well behind the rate when Tryon entered in the 14th over but she showed her striking power. She took 20 off the 18th over from Suzie Bates to leave 20 needed off 12 balls, then a six off the last ball of the penultimate over from Amanda-Jade Wellington left 11 needed for the last. That became six off four when Tryon found the boundary again, but Coyte then got the deliveries full and two singles were turned down only for Tryon to run off the penultimate ball leaving Tayla Vlaeminck needing four for a Super Over which proved beyond her. The Strikers' total looked set to be much higher after an opening stand of 85 between Bates and Sophie Devine, who was dismissed for the first time in 207 deliveries, but they struggled for boundaries in the latter part of the innings. Bates' 65 off 54 earned her the player of the match.

Melbourne Renegades' finals hopes took a major blow after the Melbourne Stars claimed just their second win of the season thanks to 62 from Lizelle Lee in a superbly timed run chase in Ballarat. Following the early loss of skipper Elyse Villani, Lee and Mignon du Preez put on 90 to take control of the chase. The pair struck eight fours and four sixes, with du Preez making 41, but their demise in the 14th and 16th over respectively threatened to derail the chase. With 42 still needed from 27 balls, Erin Osborne (34 not out off 15) and Annabel Sutherland (16 off 16) guided the Stars home with four balls to spare. Earlier, former Stars batter Anna Lanning stood tall in her first WBBL game of the season for the Renegades. A late inclusion for the absent Sophie Molineux, Lanning made 73 from 49 balls with eight four and two sixes to help set up the Renegades total of 3 for 165. Jess Duffin made 35 not out from 17 balls in a late flourish after Tammy Beaumont fell for 39 with a couple of overs remaining.

The Sydney Sixers fell to back-to-back defeats as the Perth Scorchers jumped ahead of them in the table with a crushing 52-run win to further shake up the battle for semi-final spots. Nat Sciver played a starring role with a half-century to lift the Scorchers to 5 for 152 then claimed the vital wicket of Alyssa Healy in the first over the Sixers' chase. Without the injured Ellyse Perry at the top of the order the Sixers stumbled to 5 for 35 in the ninth over from where there was no way back. Heather Graham, who had contributed a useful 25 off 14 balls, nipped in with 2 for 17. The teams face each other again in a rematch on Sunday.

Defending champions the Brisbane Heat secured their semi-final spot with a seven-run victory over the Hobart Hurricanes. Grace Harris played the key innings with the bat as her 43 off 27 balls put the Heat's innings back on course after they slipped to 4 for 58 in the 10th over. Amelia Kerr, who contributed an important 21 off 16, then struck vital blows with the ball to halt a promising start to the chase from the Hurricanes who had reached 0 for 52 in the powerplay. Kerr had Erin Fazackerley caught behind, with a juggle, first ball and then added Nicola Carey as Beth Mooney, who had a superb evening with the gloves, pulled off another excellent catch. Chloe Tryon threatened a late heist when she struck three boundaries in the penultimate over but Delissa Kimmince bowled with the third ball of the last as she comfortably defended 16.
