All four Cricket ACT A-grade matches on Saturday were rain-affected.

Riley took full advantage of the wet and humid conditions to finish with figures of 6-22 as Eastlake was bundled out for 111.

Wests-UC had a few nervous moments in pursuit of the revised 42-over victory target before reaching 6-109. It was the ladder-leader's fifth win from six games this season.

The match also marked the first loss of Eastlake's impressive campaign.

Wests-UC captain Ben Oakley, who chipped in with 3-29, couldn't believe his luck when he won the toss on a juicy Kingston Oval deck.

''It [the pitch] looked really green and it worked out that way - the ball moved around a fair bit,'' Oakley said.

''Conditions suited Dale beautifully today and he used them very effectively.

''We've had a pretty good start to the season, so heading into the Christmas break with a win against another of the top sides is really pleasing.''

Ginninderra also had reason to smile as it moved further up the table with a five-wicket win against Weston Creek.

Skipper Josh Kentwell's three wickets helped dismiss Weston Creek for 138, before Rhys Healy kept his nerve with an unbeaten 33 to guide Ginninderra to the 38-over target of 123.

Ginninderra has defeated Queanbeyan and now Weston Creek in successive weeks. Kentwell said these victories were just the tonic for his improving side going into the new year.

''Beating Queanbeyan is always a positive, and it's been a while since we've beaten Creek, so that's a cherry on the cake,'' Kentwell said.

''When we have a full-strength side, we bat all the way down to 11 and that's made all the difference.

''If a couple guys at the top don't fire, we know we've got the depth to do the job.''

Meanwhile, Shane Devoy carried on his red-hot form from the midweek Futures League match with another five-wicket haul to lead Tuggeranong to a comfortable 128-run victory against Norths.

After taking six second-innings wickets to bowl the ACT Comets to victory over South Australia, the left-arm spinner picked up 5-18 as Norths collapsed for 97 chasing a revised target of 226 from 42 overs in reply to Tuggeranong's 6-246.

Michael Barrington starred for Tuggeranong with an unbeaten 78.

Freebody Oval hosted a 16-over contest, with Queanbeyan (5-121) holding off ANU (91) by 35 runs under the Duckworth-Lewis method.
