Kieran MacDonald was put in on goal on the left by Conroy but the full back’s shot was blocked by Muir then cleared upfield.

Two minutes later Queens were fired ahead after Dario Zanatta controlled the ball from headed clearance and hammered a 25-yard volley past Rohan Ferguson to give his side the lead.

Airdrie pushed for an equaliser with Ryan blazing a 23rd minute shot high over the goal and in 36 minutes Scott Stewart attempted to chip the ball over Muir after being put clear by Adam Brown, but the keeper was alert to push the ball away.
