Nairn recorded a valuable victory at Highland neighbours Clach at Grant Street, the goals coming from the prolific Conor Gethins and defender Sean Webb.
On 22 minutes, great play by Kyle Wilkie took him past two challenges and he played in Gethins, who curled a shot inches wide.
Clach found themselves down to 10 men after only 29 minutes, Martin Callum receiving his second yellow card of the game.
Nairn took the lead on half-time with a cracking shot from Gethins who turned his man on the edge of the penalty area and powered in a right-foot shot.
Clach had a good chance to level the scoring in the 52nd minute but Wayne Mackintosh did well to block Daniel McLellan’s shot.
Nairn stunned Clach with a goal against the run of play in the 70th minute, Sean Webb climbing highest to head home a free kick to seal the win.
