Dundee remain in the First Division title race thanks to a win over relegated Stirling Albion.
The home side broke the deadlock on 55 minutes when Gary McKenzie headed home from Freddie Daquin's corner.
A few minutes later, Gavin Swankie lashed in his fourth goal of the season, with the visitors failing to clear their lines.
In the final minute, Scott Robertson ran on to a Kevin McDonald pass and slipped a neat shot into the net.
Dundee are four points behind leaders Hamilton with just two matches left and travel to Scottish Cup heroes Queen of the South next weekend.
The Accies have a superior goal difference and entertain Clyde in their next outing.
