STOW-on-the-Wold Colts beat Cirencester 16-0 with Angus Hayward scoring the only try.
The visitors dominated the first 20 minutes but Stow defended well with strong last-ditch tackling.
Having worked their way into the Cirencester half, a good line-out ball from Will Oughton was moved quickly and Hayward cut back in to score under the posts with Matt Rose converting.
Cirencester were judged to be offside soon after and Rose added another three points to give Stow a 10-0 half-time lead.
Although Stow dominated the second period, they were limited to two long-range Rose penalties.
