The Binos, who started the day in third, weren’t in action but had to watch as Elgin City and Stranraer both claimed wins to leapfrog above them.
Elgin had to overcome Queen’s Park and did it in exciting fashion, scoring twice in quick succession through Kane Hester just after the restart.
Will Baynham made it 2-1 before Hester grabbed his hat-trick goal.
Despite a late goal from Luca Connell, Elgin held on to move into third and inflict the Spiders’ second league defeat.
In Stranraer, goals from Andew Stirling and Thomas Orr sandwiched a Scott Robertson own goal to secure the three points the Blues required to make the play-offs.
At the bottom, Cowdenbeath defeated Albion Rovers 2-0 and Stenhousemuir won 1-0 at Brechin, who will likely face Kelty Hearts after they saw off Brora Rangers 2-0 in the first-leg of the promotion play-off.
