Leaders Queen of the South's seven-match winning run came to an end after a 0-0 draw with second-placed Alloa.
It was only the second time that Gus MacPherson's side had dropped points at home but it ensured they maintained their 16-point lead.
Both sides had good sights of goal in the opening period. Ben Gordon headed over following a corner for Alloa while Nicholas Clark and Ryan McGuffie went close with headers for the home side.
Daryll Meggatt was denied a spectacular goal in the second half as Lee Robinson parried away his 30-yard drive.
Christopher Mitchell tested Scott Bain in the Alloa goal from a free-kick just outside the area but neither side was able to grab a decisive goal.
