Visiting Moama Recreation Reserve, Rochester wasn’t able to defend its total of 7-89, with the Mowers batters proving too composed for the visiting attack.
Alice Caldow got Rochy off to a promising start in its batting innings, absorbing the majority of the strike in a 19-run first-wicket stand with Taya Munro.
Her pairing with Sadie Martin for the second wicket proved even more fruitful, the two advancing the total to 51 before Caldow retired not out for 27.
Delaney Laffy struck quickly for Moama to remove new batter Imogen Kath and Martin also departed for 13 the following over, quickly turning 1-51 into 3-51 with both set batters in the sheds.
The new pairing of Cadence Major and Sarah Taylor worked well to add another 33 to the total before Major was removed by Jordan Dalziel.
It signalled a steep decline in the scoring rate as Rochy only added four runs in the last three overs, limping to the end of its innings and posting 7-89.
Laffy struck three times in total for Moama, possessing figures of 3-10 from her four overs, while Dalziel snagged two wickets.
Isla Laffy and Mia Arthurson also made breakthroughs for the host.
The Moama run chase was composed as Rochester struggled to shift the opening pairing.
Olivia Davy (14 retired not out) and Beatrix Bray (12) protected their wicket well and ticked the scoreboard towards 50 with the help of a healthy extras total.
Davy’s retirement and Bray’s dismissal came in consecutive deliveries, bringing the new pairing of Delaney and Isla Laffy to the middle.
Delaney was searching for the boundary from the off, getting five fours through the ring.
She was removed shortly before the conclusion for 24 from 16 deliveries, with Isla (7 not out) hitting the winning runs in the following over to get Moama home for the loss of only two wickets.
Rebecca Wade (1-9) had the best figures in a tough day in the field for Rochy, while Keely Major (1-16) also made a breakthrough.
Also scheduled for round eight, Bamawm-Lockington United’s match-up with Kyabram was abandoned.
Rochester falls to 3-3 with this result, good for seventh on the league table.
Its next fixture will be a tough meeting with defending champion Echuca at Windridge Oval on Sunday.
