Three shots on the final end of the fours gave Lillington a dramatic victory in the County Top Club final against Rugby Thornfield.
Despite a 26-12 pairs win for Di Thurlbeck and Margaret Grosvenor against Pat Bax and Yvonne Bromfield, Lillington found themselves needing to win the fours to lift the cup on points scored after defeats in both the singles and the triples.
Sue Hornsby lost 21-15 to Abbie Ward in the singles, while the triple of Pat Gagg, Grace Gallacher and Jayne Henfrey were pipped 13-12.
The four of Jenny Corn, Hazel Goodman, Pippa Mace and Jacqui Cook picked up seven shots on the third end but did not score again until the eighth end and were trailing 18-10 going into the 12th end.
However, four shots kick-started a revival and they were level pegging at 22-all going into the 21st and final end.
Three shots then gave them a 25-22 win and ensured Lillington lifted the cup by a ten-shot margin.
