NSW kept their title defence alive with a bonus point victory over Queensland at Hurstville Oval on Thursday.
The 87-run win lifted the Breakers into third place on the Women's National Cricket League table with nine points, two behind Queensland, which lost top spot to Western Australia.
NSW are three points behind WA with a game in hand and can climb to the top of the table if they beat ACT at Hurstville on Thursday in their rescheduled match.
Chasing the Breakers' 241 for victory, Queensland were bowled out for 154 inside 36 overs to give NSW their second victory in three games this season.
Impressive bowling and batting performances from teenagers Hayley Silver-Holmes and Phoebe Litchfield were the highlights in a strong team effort from NSW.
Silver-Holmes was named player of the match after taking 3-18 from eight overs with her accurate medium pace, knocking over Queensland's top scorer Laura Harris for 65 as the visitors lost their last seven wickets for 43 runs.
Litchfield continued the impressive start to her career, scoring 44 off 40 balls in her third WNCL match. The 16-year-old left-hander, who played 11 games for the Sydney Thunder this season with a top score of 52 not out, had come to the wicket with NSW in an uncertain position of 4-132.
Litchfield went on to dominate a 65-run partnership with Ashleigh Gardner, who later took 3-28.
After a 101-run opening stand from captain Alyssa Healy (53 from 61) and deputy Rachael Haynes (53 from 93) the Breakers fell away before bright cameos from Gardner (34 from 37), Litchfield and veteran St George star Rene Farrell (22 not out) lifted NSW towards a competitive total.
NSW host the Meteors at Hurstville on Thursday, with play to start at 10am.
