----------------------------The Scorchers were well poised to chase down their target of 146 until a catch on the boundary by Thunder fielder Lisa Griffith dismissed Nicole Bolton for 71 in the 18th over, leaving the hosts needing 20 runs from the final 14 deliveries. On the last ball of the match, Scorchers batter Mathilda Carmichael was run out by a metre while attempting a game-tying run, therefore securing victory for the Thunder by the narrowest of margins.----------------------------
