The Mowers put together a complete batting display at Moama Recreation Reserve, leaning on captain Delaney Laffy and several supporting innings after being sent in.
Laffy had two major stints at the crease, first retiring on 37 after hitting the balls limit.
Her partnership with Beatrix Bray (25) was particularly impactful, but Cooma did well to keep the rest of the top and middle-order quiet.
Wickets fell throughout the 35 overs, and Moama looked as if it may not complete the innings, but late resistance from Lylah Newman and a returning Laffy saw the Mowers through.
Coming together at 9-189, the pair added another 31 to the total, Laffy blasting the ball to all corners to finish with 75 not out from 49, while Newman posted 31 not out from 44.
Heather Munro was Cooma’s best with the ball, taking 3-28, while Jinaya Nurse struck twice.
Moama finished with 9-220, a tall task for Cooma to chase down.
Things started poorly for the visitor, with co-captains Jorja Tranter and Breanna Baker both gone without score in the opening overs.
Remaining opener Emma Napier was resolute but couldn’t make an impact on the scorecard, leaving Sophie McDonald and Jinaya Nurse to try to steady things.
The two put on the best stand of the innings, adding 35 and getting Cooma past 50, but McDonald’s retirement started another procession of wickets.
Olivia Davy went on a rampage with the ball, taking four wickets in three overs, including the valuable scalp of Nurse.
McDonald (12 not out) quickly found herself back in the middle, but the innings was unsalvageable, and after she ran short of partners Cooma was dismissed for 73.
Davy finished with 4-10 as Moama’s best, while Jordan Dalziel bowled six overs, recording five maidens and finishing with 3-1.
With the win, Moama kicks a game clear of Rochester at the top, while Cooma continues to languish at the base of the table.
The league is on a break this weekend, before Cooma hosts Nathalia on February 1.
Moama will see Katamatite visit Moama Recreation Reserve.
