Match ends, Dumbarton 5, Alloa Athletic 0.
Dumbarton defeated Alloa for the second time in four days to set up a Scottish Cup fourth round tie against Queen of the South.
The Sons had the upper hand after just 19 seconds when Donald McCallum struck from 20 yards.
Garry Fleming heaped more misery on manager-less Alloa by converting at the end of a fine Dumbarton move.
Jordan Kirkpatrick fired a nice third for the hosts before he and Calum Waters hit two more in added time.
So no Scottish Cup sweetener for the Clackmannanshire side just 24 hours after Danny Lennon resigned as boss.
Having held his hands up and walked, Lennon has departed with enough time for a successor to try and find a solution to what is now eight straight defeats, with Alloa also six points adrift at the foot of the Championship.
On the other hand, Dumbarton's decent season under Stevie Aitken is enjoying a little spike; the 2-0 league win at Alloa on Saturday followed by a successful passage to the last 32 of the country's most precious cup competition.
They were on their way in a jiffy. McCallum benefited from a Robbie Crawford slide tackle in the middle of the pitch that presented him with the ball, and before much longer McCallum had scuttled away and drilled the ball low into the bottom left corner while many home fans were still settling into their seats.
Kevin Cawley, who joined the Sons from Alloa, initiated the second goal with composed play and a great pass out to Grant Gallagher on the right.
The former Stranraer midfielder's low cross was turned in from six yards by striker Fleming to seal the tie less than quarter of an hour into it.
One of the early runners for the Wasps' managerial role is 31-year-old striker Michael Chopra, who came off the bench after 28 minutes to replace Crawford.
That swap resulted in more Alloa possession and forward play but nothing of real note was created until the second half, when Michael Duffy shot far too close to Brown following persistent approach play by Graeme Holmes.
Dumbarton did not trouble Alloa too much in the second half, but did ensure they wrapped things up through Kirkpatrick's rising, arrowed strike across visiting goalkeeper Andy McNeil.
Duffy later watched his goal-bound low effort cleared off the line; another reminder that it just is not happening for Alloa at the moment.
Waters received a square ball on the break to steer in Dumbarton's fourth and Kirkpatrick made it even worse for caretaker Alloa boss Paddy Connolly by hitting a fifth in at the near post.
