The 25-year-old hit 101* runs off 42 balls in the Wednesday afternoon clash to eclipse Sixers star Ashleigh Gardner’s previous record of 47 deliveries from achieved last season.

Needing just one run to clinch victory Harris sat on 95 but wanting her teammate to reach triple figures, Beth Mooney made Harris stay put despite hitting the ball.

The allrounder struck a massive six down the ground to reach her century on the next delivery.

Harris finished the innings with five sixes and 13 fours.

She reached her half-century from 23 balls and was lucky to stay in after her hit was dropped on 92 by Erin Osborne.

The opener had already broken the record for fastest WBBL half-century by a Heat player earlier in the season during a 28-ball 54.

Harris is the first player two score two WBBL centuries, having already scored a ton during the first edition of the competition.
