McDonald then put Johnson clean through on Fotheringham, but the keeper again frustrated the Steelmen with a fine save.
The Light Blues’ Andy Halliday sent a powerful shot just over from outside the box before ‘Well keeper Craig Samson turned a Martyn Waghorn shot over. Kenny Miller’s effort then went just wide of Samson’s far post after a James Tavernier cross.
