Second Division bottom club Albion Rovers got off to the perfect start and then dug deep to complete a rare win over Stenhousemuir.
Patrick Walker supplied the chance from the right for Christopher Dallas to strike home in the first attack of the match - barely 10 seconds into the encounter.
A dogged defensive display in the face of increasingly frenzied Stenhousemuir attacks was the order of the day for the visitors.
The closest the hosts came to levelling was four minutes from time when Rovers keeper Matthew McGinley saved Bryan Hodge's 12-yard effort.
