A powerful batting performance gave the New South Wales Breakers a 1-0 lead in the best-of-three finals series against Queensland Fire at North Sydney Oval.
Set 175 for victory, NSW started well with a 51-ball 50 to Alex Blackwell before Leah Poulton's unbeaten 70 and Michelle Goszko's 48 sealed the eight-wicket win.
Kasee Marxson guided Queensland with 72 but only three other batters reached double figures as they were dismissed for 174 in 48 overs.
Sarah Andrews was the best of the NSW bowlers with 3 for 35 while Emma Liddell, Julie Hayes and Nicole Goodwin picked up two each. The second match is at the same ground on Saturday with the third final on Sunday if required.
