A remarkable innings from skipper Jess Duffin guided Melbourne Renegades to a five-wicket win in a last-ball thriller against Hobart Hurricanes at Junction Oval.

The Renegades had slumped to 3 for 12 in the chase of 151, having lost international stars Tammy Beaumont and Danni Wyatt in the space of three balls. But Duffin took control, making 75 from 49 balls with eight fours and four sixes. She shared in a 42-run stand with Josie Dooley, who contributed just 8, before putting on 78 with Courtney Webb. The pair reduced the equation to 20 off 20 when Duffin fell. Webb was out to a superb return catch by Nicola Carey in the last over, but Georgia Wareham and Maitlin Brown scrounged the three runs needed from the last three balls to win the match.

Earlier, Corinne Hall had made an excellent unbeaten 50 in a key 82-run stand with Fran Wilson (45) to help Hobart overcome a poor start to post 5 for 150.

Perth Scorchers bowler Heather Graham held her nerve to secure a two-run win in another last-ball thriller at Karen Rolton Oval to deny Bridget Patterson stealing victory for the Adelaide Strikers.

The home side had been set 174 to win after England batter Amy Jones and Australia captain Meg Lanning smashed half-centuries during a 141-run opening partnership. Jones finished with 80 from 58 balls while Lanning made 64 from 50.

The game looked beyond the Strikers' reach when Sophie Devine was bowled by Nat Sciver for 58. The Strikers needed 42 from 20 balls after that, but Patterson nearly pulled off a miracle. She made her highest WBBL score, clubbing six fours and three sixes in her 60.

Graham had 11 runs to defend in the final over. She had Lauren Winfield dropped first ball before Patterson pulled her through square leg for a boundary. Graham conceded just two singles from the next three balls leaving Patterson with four to win from the last. She couldn't find the rope and was run out trying for a second.

A disciplined bowling display from the Brisbane Heat helped them defeat Sydney Sixers for the second time this season at North Sydney Oval.

Just a week after their record-breaking partnership, Alyssa Healy and Ellyse Perry were both dismissed cheaply in the powerplay. Sammy-Jo Johnson bowled Healy with a peach while Perry was adjudged lbw to a ball that darted a long way off the seam from Delissa Kimmince.

Johnson delivered her four overs for just 11 runs and Jess Jonassen bagged 2 for 20 from her four overs as the Sixers struggled to 7 for 123.

The Heat cruised to victory in the chase, winning with 19 balls to spare and seven wickets in hand. Jonassen top-scored with 33 in a superb all-round effort but there were even contributions from the Heat's top five.
