A scrappy opening half hour with just the one goal, apart from that there hasn’t been many clear-cut chances as County still lead.

A massive win in the relegation fight for the hosts although they still remain bottom with Aidrie drawing with Partick Thistle. A massive game for County next week with Morton if they are to avoid the drop.
