The win, the first time this season they’ve put back-to-back victories together, lifts Jim McIntyre’s side off the foot of the table and up to 10th spot, although, they are still involved in a three-way battle with Motherwell and St Mirren both of whom are level with County on 18 points.
The visitors’ victory also drags Partick that little bit closer to becoming involved in the relegation dogfight.
Staggies boss McIntyre said: “It was a great result for us and the boys dug really deep and deserve great credit for the last two results, they’ve shown character and spirit.
“There’s still a long way to go, but we’re delighted with the result and performance.”
Disappointed Jags boss Alan Archibald warned his players they’re getting too close to the bottom pack for comfort.
He said: “We were really disappointing today, the team with the desire and hunger won.
“I’ve told the players that we are now involved in the fight at the bottom. We need to start winning games.”
Craig Curran opened the scoring for County in the first half after a mix up in the home defence saw him given space in the six yard box to fire past Paul Gallacher.
The striker went on to miss a second half penalty – awarded when Dan Seaborne brought down Liam Boyce – before Raffaele De Vita increased the Staggies lead.
On-loan hitman Lyle Taylor handed Jags a lifeline shortly after, but almost immediately full back Marcus Fraser produced a superb effort to put the result beyond any doubt.
