Bryan Prunty converted two second-half penalties as Airdrie kept their play-off hopes alive and pushed us to the brink of League 2 football next season.
We head for Brechin next weekend 11 points adrift of both Stenhousemuir and Ayr United and will be relegated if we fail to win at Glebe Park.
Binos boss Stuart McLaren made three changes to the team beaten 4-0 at Forfar – Angus Beith replaced the suspended Craig Comrie, Gordon Smith came in for the injured Lewis Coult and Kevin McKinlay got the nod in place of Chris Smith. There was a debut for U20 midfielder Jordan Sinclair, who replaced Willie Robertson late on.
We started the game well and Robertson saw a shot blocked before Andy McNeil pushed out an effort from Andy Stirling but the Diamonds came to life as half-time approached and Callum Reidford made a couple of fine saves to keep the score level.
Airdrie, who have lost only to leaders Stranraer on their travels since September, took the lead in 53 minutes when Prunty found the corner from the spot despite Reidford getting a hand to the ball.
The kick had been awarded when Bob McHugh, on loan from Motherwell, went down under a challenge from his Fir Park team-mate Adam Cummins and the visitors went close again when Luca Gasparotto headed against the bar following a corner.
We struggled to make inroads and Airdrie sealed the points 11 minutes from time when Prunty smashed his penalty down the middle after Brian Colvin deemed Ross Forsyth had impeded on-loan Dundee United midfielder Scott Fraser.
