|Sons push forward|
The visitors went in front on 27 minutes after a scrappy start, but Andy Geggan equalised on 41 minutes with a fine looping header.
In the second half Sons put themselves 2-1 up through a piledriving Jon McShane shot six minutes after the restart. Then defensive uncertainty allowed East Fife to draw level again.
But two fabulous goals from Mark Gilhaney and McShane again, on 68 and 77 minutes respectively, put the game beyond all doubt and gave Dumbarton another morale-boosting victory.
