Kilmarnock earned a potentially vital three points in their bid to remain in the Scottish Premiership as Bruce Anderson's first-half header and Liam Donnelly's fine finish saw off relegation rivals Ross County.
In a tense, competitive encounter of limited chances, Derek McInnes' side broke the deadlock, when Danny Armstrong delivered a ball deep to the back post and Anderson rose to beat a tight angle and Jordan Amissah in goal.
That moment proved a platform on which Kilmarnock built, with Donnelly securing the win with a fine individual goal full of determination.
The win moved the Ayrshire side three points clear of 11th and a considerable nine above bottom-placed St Johnstone, who they face next weekend in Perth.
County failed to muster an effective response to falling behind as they fell to a fifth straight defeat. They now sit two points below Dundee in the play-off position.
Every result from now until the season end is going to be vital. And it felt that if either side won this, they could breathe a little, albeit with work to do.
Over half an hour in, not one genuine chance had been created and that perhaps spoke of the pressure on both to deliver. Plenty of endeavour but little quality.
Goals do indeed change games and did so here. Armstrong had the first decent shot moments before delivering a perfect ball for Anderson to attack and he did so to score a crucial, crucial goal.
That lifted the crowd and while Ronan Hale went close from an angle, the visitors just couldn't threaten enough to change the course of the game.
McInnes' side seemed determined to determine their own fate and, after a number of second-half chances, broke through when Donnelly showed great intent to juggle the ball and then fire home the vital second.
