Brisbane Heat 124 for 4 (A Kerr 59) beat Hobart Hurricanes 120 for 8 (Villani 58*) by six wickets
Kerr, who Heat knew would have a delayed arrival when they took her as expected in the draft, guided the run chase after a miserly performance with the ball in her first appearance of the season.
Kerr had success in her second over when she removed Heather Graham lbw amid a stuttering Hobart Hurricanes batting display and later added Ruth Johnston with her final delivery.
When Grace Harris was lbw to Molly Strano’s first ball – beaten by one which went on with the arm – there was belief in the Hurricanes camp and Shabnim Ismail removed Georgia Redmayne to leave them 26 for 2.
However, from there Kerr had things under control with a 38-ball half-century, adding 57 for the third wicket with Mignon du Preez before Knott helped finish the chase.
Ismail was again impressive with the ball, sending down 13 dots in her four overs.
