Ross County maintained their three-point advantage at the top of the Scottish Football League First Division with victory over Partick Thistle.
The visitors came close to taking the lead when Colin McMenamin volleyed against the crossbar.
But County did find the net in the 26th minute, Iain Vigurs firing home with a superb shot from 25 yards.
Vigurs forced a save from Thistle goalkeeper Ryan Scully on the hour-mark.
Kris Doolan had a chance to level for the hosts late on but his long-range volley was parried away by goalkeeper Michael Fraser.
