Brisbane Heat took second place in the WBBL ranking after Sydney Sixers fought seven wickets on Saturday in the North Sydney Oval.
In a rematch in the final of last season, the reigning champions had no trouble getting past the modest 7-123 of the Sixers with 19 balls and overtaking them and Adelaide Strikers in the standings.
With her sister Grace Harris (26 out) at the other end, Laura Harris increased the heat for the fourth consecutive victory over the Sixers by hitting Hayley Silver-Holmes over the long fence for her second six.
Openers Beth Mooney and Maddy Green each scored 25 goals, and Jess Jonassen, who scored 33 with 33, scored a good all-round game before the Harris sisters ended the chase with a bang.
Leg spinner Dane van Niekerk (2: 19) was the bowler’s choice after the Sixers, who started terribly, had recovered in the middle and stalled late, had previously hit the record with the club.
Six days after Alyssa Healy and Ellyse Perry joined a record-breaking, unbroken opener with 199 missions, they both left cheaply to turn their backs on the Sixers.
Healy was poked by a peach by Sammy-Jo Johnson for five minutes before Perry, who scored 139.50 points on average in this WBBL campaign, was caught by Delissa Kimmince for two to two plummets.
Van Niekerk (28), Marizanne Kapp (26), Ash Gardner (24) and Erin Burns (23) intervened with cameos, but no Sydney batsman was able to turn their start or their arms against an impressive heat -Bowling to free.
Players of the game Jonassen (2-20) and Kimmince (2-26) were the main destroyers, while Johnson (1-11) was stingy with the new rock.
