A magnificent winner from debutant Graeme Jones sealed a hard-fought win for Clyde against plucky Airdrie Utd.
But the in-form visitors missed a series of chances and enjoyed by far the bulk of territorial advantage.
Martin Hardie, twice, Mark Roberts and Owen Coyle all went close to breaking the deadlock and Coyle had a 12-yard shot deflected to safety.
But Mark Gilhaney set up morning signing Jones to blast home a memorable winner from 20 yards on 78 minutes.
