Brisbane heat 139 for 6 (du Preez 60, Schutt 2-29) won Adelaide Strikers 137 for 4 (Penna 57*, Knott 2-15) for four wickets
Chasing 138 to win after a disciplined bowling performance that only faltered late in the innings, du Preez controlled the Heat’s chase with 60 off 49, while bowling brilliantly to the spinners.
But there was a brief wobble when Amanda-Jade Wellington caught and bowled her and Megan Schutt had Jess Jonassen caught soon after.
But England’s Bess Heath was able to take the hosts home with a lead that went to the limit with one ball to spare, after some nervous balls from Gibson in the final over.
Danielle Gibson also hit 34 off 17 balls, helping lift the Strikers to a competitive total of 137 for 5. But it wasn’t enough.
The result snapped the Strikers’ four-game winning streak, leaving them one point behind table-topping Sydney Thunder, tied with Perth Scorchers, and two points ahead of the fourth-placed Heat.
