Melvin De Leeuw's first-half strike was enough to give Ross County all three points against St Johnstone at McDiarmid Park in the Scottish Premiership.
De Leeuw fired past Alan Mannus with 29 minutes played to give the visitors the lead in what was the first real opportunity of the game.
The Saints almost hit back before the interval through Dave Mackay, who headed Lee Croft's cross just wide of the target.
Tommy Wright's men came close once more when Steven Anderson met a header at the back post, but the visiting side scrambled the ball away to keep hold of their lead.
Stevie May was the next St Johnstone player to come close to levelling the contest, but his overhead effort was tipped around the post by Mark Brown.
