BLU won the toss and sent Rochester in to bat, with Cadence Major and Sarah Taylor at the crease for the first deliveries of the new season.
Major quickly found herself back in the sheds thanks to a nifty piece of work from Daneika Hucker, who reeled in a catch off her own bowling.
Hucker also dismissed Taylor for six, putting Rochy in early trouble.
Miranda Crawford steadied the innings with a valuable 10 before she was run out by the combination of Hucker and Bree Styles.
The presence of debutant Taya Munro in the middle for Rochy was a welcome one, her important 20 from 31 deliveries eventually leading her side to a defendable 84 all out.
Styles was the pick of the bowling unit for BLU, taking a tidy 4-11, while Hucker grabbed two wickets and Aurelia Kemp and Chloe Forster chipped in one each.
The BLU run chase started with promise as openers Amy Fitzgerald and Styles ticked the score over to 20 without loss.
Ruby Brentnall linked up with Styles and the pair put BLU into a strong position, before Brentnall’s wicket placed the score at 2-35.
Unfortunately for the Lions, the middle order wasn’t able to replicate the success of its earlier batters and wickets began to tumble cheaply.
BLU lost six wickets for just 14 runs, with mishaps between the wickets a key contributor.
Two were lost via run-out during this stretch, while the Lions’ final dismissal also came between the wickets as BLU slumped to 62 all out, 22 runs short of Rochy’s total.
Styles’ 13 was the best score among the BLU batters, while for Rochester seven players got their name on the wicket-takers list, with Rebecca Wade (2-6) the only bowler to strike twice.
Next week’s matches see BLU travel to Cooma, while Rochester has the bye.
