Adelaide Strikers 164 for 3 (Wolvaardt 73) beat Hobart Hurricanes 87 (McGrath 3-8) by 77 runs

The in-form Adelaide Strikers are pulling all the right moves in pursuit of back-to-back WBBL titles, thrashing the Hobart Hurricanes by 77 runs in their last game of the regular season.

Strikers won Sunday's game with a patient first innings anchored by Laura Wolvaardt, who it was later confirmed will be available for the final despite having been named South Africa captain, and Tahlia McGrath's WBBL career-best bowling figures that helped trigger a batting collapse of 6 for 25.

Chasing 165 runs for victory at the SCG, Hurricanes were all out for 87 runs, their sixth-worst total in a WBBL game.

The loss officially ended Hurricanes' hopes of clinching a berth, though they would have needed a minor miracle to oust the Sydney Thunder and finish fourth.

Strikers had already locked up top spot on the ladder and hosting rights for the tournament final, which they will enter on a five-game winning streak and with six days between games.

With the ball, Strikers spinner Jemma Barsby sparked the mayhem, bowling veteran Elyse Villani for the first of six wickets to fall in the space of five overs.

Captain McGrath was the most influential with the ball, snaring Nicola Carey and Naomi Stalenberg in back-to-back deliveries to consign Hurricanes to 49 for 4 after they were 41 for 1.

After Strikers were sent in, South African opener Wolvaardt formed a steady 67-run partnership with Katie Mack to get the ladder-leaders moving.

Wolvaardt brought her half-century up in the 16th over with a single to deep square leg from Carey's bowling.

She cut loose late with back-to-back boundaries in the 19th over, including her only six, before being caught in the deep from the penultimate delivery of the innings. Strikers added 100 in their second 10 overs.
