Airdrie boss Ian Murray refused to criticise Callum Smith for missing a sitter in their draw with Queen's Park as they blew the chance to close the gap on leaders Cove Rangers.
Charlie Fox's stunning opener for Spiders was cancelled out by Scott McGill effort from a Smith assist within the space of a minute.
But the defining moment in the game cropped up on the stroke of half-time when Adam Frizzell laid the ball on a plate for Smith to net from six-yards, but he fired wide on the bobbly Firhill surface.
