Former Ayrshire county youth player Calum Nairn (Kilmarnock Barassie) shot his lowest round of the year - a six-under-par 66 - to give himself a chance of achieving his first win of the season, in the 36-hole St Andrews Brewing Company 36-hole Order of Merit event at Deer Park Golf and Country Club, writes Colin Farquharson.
Nairn had a bag of eight birdies and two bogeys in matching halves of 33 after standing four under par after eight holes.
At the halfway point, he leads by one shot from Neil Fenwick (Dunbar) and Chris Currie (Caldwell).
