Dumbarton produced one of the surprises of the CIS Insurance Cup first round with a comfortable win over Second Division Stirling Albion.
But the side relegated last season left it late to claim their three goals.
A David O'Brien drive had struck a Sons post before David Bagan tapped the ball home after a powerful John Gemmell effort hit the Stirling upright.
Chris Boyle added another close-range strike before Gemmell unleashing a powerful shot into the back of the net.
