Cleckheaton made a notable impression on their Black Sheep Yorkshire Champions' Trophy debut, knocking out holders Hoylandswaine.
With Saturday's rain replaced by warm, breezy conditions the following day, the match was watched by a good-sized crowd, who witnessed a determined performance from the hosts.
Cleckheaton were given a fine start, openers Andy Gorrod (38) and Tim Jackson (27) sharing a stand of 72, but they didn't fully capitalise on it, and their total of 204 looked 20 or 30 runs below par.
The middle order melted away and they were indebted to Ian Nicholson, whose 56 included three sixes and four fours, for taking them past 200.
Nicholson remained calm while his colleagues perished in disappointing manner.
With their Huddersfield League rivals noted for their batting prowess Cleckheaton, who were without the services of opening bowler Iain Wardlaw (on Scotland duty), knew they had to bowl well.
They responded to the challenge in a manner that pleased their captain John Wood.
His brother Ian checked Hoylandswaine's progress with a fine spell of 3-30 and then leg-spinner Tanzeel Altaf (4-27) hastened Hoylandswaine's decline to 148 all out.
Their top scorers were former Bradford League players Richard Wilkinson (32) and Alex Morris (31), who had spells with Bradford & Bingley and Hanging Heaton respectively.
The JCT600 Bradford League champions will now face the Solly Sports Yorkshire League champions York at home in the semi-finals - another tough assignment.
