Dumbarton are into the fourth round of the Scottish Cup after they thumped Scottish Championship rivals Alloa Athletic.
In the only all-Championship tie in the third round, the Sons took only 19 seconds to take the lead as Donald McCallum took aim from the edge of the area and drove the ball past Andrew McNeil.
Dumbarton, who moved into seventh place in the league after winning at Alloa on Saturday, showed confidence in possession, with McCallum continuing to torment the Wasps' defence.
The hosts scored a second on 14 minutes when Grant Gallagher's low cross was turned into the net by Garry Fleming.
Alloa tried to pull a goal back before half time, but Steven Hetherington curled his free kick narrowly wide of the target.
Athletic started the second half brightly, but were unable to make their pressure count as the Sons scored a third through Jordan Kirkpatrick.
Dumbarton then wrapped up a comfortable win when Calum Waters added a fourth in the dying stages, moments before Kirkpatrick rounded off the scoring in the second minute of stoppage time.
