Stenhousemuir never recovered from Bryan Prunty's early sucker-punch as Dumbarton ran out 3-0 winners in the Scottish Second Division.
The victory was an eighth in nine outings for the upwardly-mobile Sons, who consigned Davie Irons' Warriors to a third straight defeat.
Dumbarton took the lead in spectacular fashion after just 52 seconds.
Racing onto a punt forward from Scott Agnew, Alan Lithgow scooped the ball across the face of goal for Prunty to lash home an acrobatic overhead kick.
Kevin McKinlay saw his drive blocked by Lithgow before Andy Rodgers headed over the crossbar as the visitors strived for an equaliser.
In the 32nd minute, however, Mark Gilhaney was on hand to double the hosts' lead, neatly converting James Creaney's cross from the right.
In a cagey second half, Stenhousemuir might have reduced the deficit but Gary Smith headed Stevie Murray's corner tamely over the bar.
The match was settled in the 75th minute, though, as Agnew fired an unstoppable rocket into the top corner from 30 yards.
