A late goal from Ross County substitute Gary Glen lifted the Scottish Premier League rookies to third in the table with a win against Aberdeen.
Glen replaced Ivan Sproule for the final 18 minutes at Pittodrie and the move paid off when the former Hearts man found the net 10 minutes later.
The result leaves County behind Highland neighbours Inverness only on goal difference in what is fast becoming a fairytale season for Derek Adams' side.
The Dons remain outside the top six by a point and will have to await tomorrow's results to see how the table shapes up.
In the Third Division, meanwhile, Rangers were held to a 1-1 away draw with Stirling Albion.
Andrew Little opened up the scoring after just 16 minutes to seemingly put the runaway league leaders on course for victory, but Ross Forsyth found an equaliser shortly after half-time as the home side picked up a share of the points.
The Albion home ground is the only Third Division venue at which the Glasgow giants have failed to emerge victorious this season, after their first visit in October ended in a shock 1-0 defeat.
