Inverness-bound Don Cowie's injury-time equaliser gave Ross County a precious point in their battle against relegation from Division One.
Partick Thistle's Simon Donnelly almost scored direct from a cross, but Alex Keddie booted the ball off the line.
Thistle took the lead when top scorer Mark Roberts took a pass from Billy Gibson in his stride and unleashed a superb 30-yard drive.
But Cowie volleyed home after Thistle failed to clear a corner.
