Sydney Sixers 180 for 4 (Healy 107*, Devine 2-29) beat Perth Scorchers 176 for 4 (Mooney 75*, Kapp 68, Gardner 2-30) by six wickets
After going for 17 runs off her previous over, Scorchers captain Sophie Devine had Perry (48 off 40) dismissed and Healy dropped in a fine 19th over that left the Sixers still needing 14.
Healy watched from the other end as Ashleigh Gardner hit the first two deliveries for six. She was bowled from the next ball and Piepa Cleary was on a hat-trick after claiming Erin Burns next ball. Nicole Bolton chipped that delivery just short of deep midwicket for a single and then, with one to win off the final delivery, Healy gave herself room and calmly dispatched the winning runs to the cover boundary, letting out a boisterous cry in the process.
No other player has scored more than three WBBL hundreds, Healy’s century coming off 62 balls and featuring a one-handed six over mid-off.
Victory keeps Sixers on top of the ladder. Scorchers, who beat them last week, could have jumped above them from fourth with victory.
