The Flames went into the round as the only 2-0 side, but couldn’t match the one-day competition leader Moama at Northern Oval.
Fire Brigade sent the Mowers in but may have regretted its decision as openers Russell Stockdale and Anthony McMahon immediately went on the attack.
A Stockdale boundary off the first delivery set the tone and the pair put on 71 in eight overs before McMahon departed for 48.
Stockdale would bat through and go on to post a massive 94 from 60 balls, caught on the final delivery attempting to secure his century.
Jack Russell was also aggressive when called upon, making 26 from 14.
Moama posted an intimidating 5-190, leaving Kyabram plenty to do in the second innings.
When the wickets did come for Ky, Cooper Fawcett (2-31) and Jackson Barnett (2-41) were the main perpetrators.
The Flames started poorly and the run chase never really recovered.
Two of the top five went for first-ball ducks, while two others also failed to fire, Fire Brigade 4-7 within four overs.
The Flames’ three best contributors steadied the innings from the middle order, Jake Gascoyne (14), Cooper Fawcett (26) and Miller Griffiths (13) moving things along to a more respectable 6-64, but Fire Brigade was never a threat to make the required runs.
The tail came and went and the host was dismissed 11 balls early for 78.
Billy Gallagher tore apart the top order, taking the first four wickets within eight balls and finishing 5-10.
Stockdale added two wickets to his 94, while Duane Johns also picked up a couple in seven balls.
Fire Brigade’s previous victories kept the side in fourth spot, with the semi-finals ahead on Thursday.
The Flames will visit Echuca South, which finished on top of the ladder, while Moama will battle defending champion Bamawm-Lockington United in the other semi.
