Brechin City recovered from back-to-back defeats to record a victory over fellow promotion hopefuls Arbroath.
The Red Lichties remain stuck in fifth, still two points behind Forfar Athletic, who also lost away to Alloa Athletic.
Ray McKinnon's Brechin had lost four of their last five, allowing their opponents to move to within five points of them in the table.
But second-half goals from Andrew Jackson and Gerard McLauchlan all but secured them a top-four spot.
Graham Bayne's early header was punched clear by Michael Andrews in a first half, during which goalscoring opportunities were at a premium.
The deadlock was eventually broken in the 64th minute as David McKenna's cross found Jackson in the area and the striker headed in his 16th goal of the season.
Brechin's victory was secured with four minutes left as Arbroath failed to clear a corner and McLauchlan stabbed in from close range.
