Scottish League One leaders Greenock Morton fell to their first defeat in nine games as goals from James Dale and Gavin Malin gave Forfor Athletic a 2-0 win at Cappielow.
However, Morton stay top as second-placed Stranraer saw their clash with Stirling Albion postponed after the Forthbank Stadium turf failed a pitch inspection.
Brechin City could only manage a goalless draw with Airdrionians leaving them fourth behind Forfar and Stranraer.
Dunfermline Atheltic closed the gap with a 2-1 win over Ayr United thanks to Nicky Devlin's own goal and a second-half strike from Andrew Geggan, but it remains a four-horse race at the top of the table.
Elsewhere, Colin McMenamin's 13th goal of the season and a further effort from Josh Watt saw Stenhousemuir climb away from trouble with a 2-1 win over Peterhead.
Results in full: Brechin City 0-0 Airdrieonians, Dunfermline Athletic 2-1 Ayr United, Greenock Morton 0-2 Forfar Athletic, Stenhousemuir 2-1 Peterhead, Stirling Albion P-P Stranraer.
