The head of Ross Graham with 15 minutes left without a dundee united all-but mathematically secured their place in the first six of the Scottish Prime Minister William Hill.
The match was sometimes frantic against Ross County, but it lacked quality before the goal, so it was perhaps appropriate that the crucial moment of the game came from a certain part in the 1-0 victory.
While Don Cowie made a single difference in his starting lineup with Alex Samuel taking the place of Nohan Kenneh, the opposite number Jim Goodwin made two changes to a team that had been annoyed over their loss in the Derby throughout the international holiday.
Declan Gallagher and Allan Campbell left, with Ross Dochety and Craig Sibbald in the starting lineup.
Josh Nisbet raised Noah Chilvers to have a clogged effort from the edge of the box, and Dundee United had two ratings for fines – both went with a foul -free field decision.
In the middle of the first half, the circuit was inch away from the note when Eli Campbell’s long jumping struck Kacper shkel, only for the visit of the Jack Walton visiting goalkeeper to overcome the effort of Smother Alex Samuel from close range.
In the 69th minute, United will feel like they should have gone ahead when Graham run a corner to the ground just to see him dance a post.
A similar scenario would see the side of the blocking removal, with Dundee United practically repeating this action five minutes later, but this time Graham would find the net to place visitors in the lead.
After a while, Campbell was needed to make a spectacular cleaning from his line to prevent Louis Moult from making it 2-0.
Sam Dalby could have scored late, but he saw his head flying straight into the hands of Jordan Amissah.
Although there was a lot of late drama in Dingwall this season, including in the first meeting between these two sides, the county could not find a draw to save something about their efforts.
Victory means that Dundee United are six pure points of St. Mirren’s seventh with two games to go up to the highest flight divisions, while Staggies are four points behind the hearts of the sixth and four pure places of the Play-Off.
