Albion went to the top of Scottish Three after a 6-0 thumping of sorry East Stirling.
John Bradford's early double gave Rovers the ideal start and Iain Diack made it 3-0 before the break.
Todd Lumsden's 51st-minute goal preceded two from Diack to complete his hat-trick and seal the victory in style.
The win puts Albion a point clear of Morton, who beat previous table-toppers Peterhead 1-0 to climb into second.
Alex Williams' sixth-minute goal was the difference between the sides.
East Fife also climbed ahead of Peterhead - into third - after a 1-1 draw with Queen's Park
Steve Moffatt put Queen's in front on 71 minutes but Kenny Deuchar's late penalty ensured the Fifers snatched a point.
In the day's other games Gretna beat Montrose 2-0 and Stirling sank Elgin 3-0.
