A stoppage-time winner again decided Airdrie's fate - but this time it went against the Diamonds after Jim Lister had given them a first-half lead.

Three times in their last four matches have Airdrie scored first against their opposition but have won only once.

The first half saw the Diamonds far more threatening than their visitors. In 5 minutes Watt’s pass, wide left to Boyle saw the skipper fire an angled shot wide of Douglas’ goal.

With quarter of an hour played a Prunty lay to Watt saw the midfielder’s shot for goal blocked. Boyle gathered the ball on the left and sent over a decent cross that Lister rose to meet but could only head over the goal.

Richards-Everton was next to have a go when he got on the end of Watt’s free kick in 17 minutes, and then watched his flicked header fall wide of the Dundee right post.

Airdrie eventually took the lead in 21 minutes.

Prunty, almost in one movement gathered the ball from a throw in down the right touchline, turned into the penalty area and volleyed a terrific shot against the bar.

Gray reacted quickly, picking up the rebound, made space for himself before sending a delicate chip back across the face of Forfar’s goal. Lister rose high to head the ball into the net for the opening goal.

2 minutes later Prunty volleyed a flick on from Lister well over the goal.

Forfar’s first real effort came in 27 minutes when Husband struck a shot from 30 yards out that McNeil took comfortably.

Forfar went close to equalising in 34 minutes when a 25 yard drive by Swankie struck the crossbar before bouncing down then away from the goal.

5 minutes from the break a swerving shot from Boyle on the left was pushed away by Douglas.

Forfar began brightly after the break with Kader and Denholm blasting a couple of shots high over the goal in the first ten minutes. In between a Gray back post cross had Douglas struggling to take the ball and impeding Lister as he tried to move in on the loose ball.

With 63 minutes gone a Watt free kick found Proctor who headed the ball back across goal and Prunty was unable to make good contact, allowing Douglas to gather easily.

At the other end a minute later, Forfar equalised.

Patterson crossed from the left and Richards-Everton slipped as he went to attack the ball. Hilson stood unmarked and was able to nod the ball past McNeil to make it 1-1.

With 5 minutes remaining substitute Fotheringham fired a speculative 35 yard shot that McNeil had to react quickly and turn away for a corner.

A long ball forward in 87 minutes saw some great play by Parker who held off his man then picked a slide rule pass for Gray heading into the box but he fired the ball straight at Douglas.

As stoppage time ticked away Forfar grabbed a winner when a cross from the right was headed powerfully past McNeil by Swankie to leave Airdrie still looking for some home comforts.
