Whitehill trailed Selkirk at half-time but with the elements in their favour after the break the Ferguson Park faithful were treated to an attacking display of football.
Selkirk, with the wind at their back, took the game to Whitehill and Jon McInally curled a 20-yard shot into the top corner with ten minutes gone.
Only seven minutes later, Phil Addison found himself in space and coolly drilled a low shot from ten yards behind Bryan Young. Midway through the first half, Whitehill reduced the deficit when a John Hall cross from the right was headed powerfully into the net by Aaron Somerville.
The second half was only eight minutes old when Somerville slammed a shot off the underside of the crossbar behind the Selkirk goalkeeper Jamie Newman for 2-2.
Whitehill took the lead on the hour when a Wayne McIntosh cross was converted by Somerville to earn the striker his hat-trick. After some slack defending from Selkirk, Stevie Manson lobbed the ball from fully 35 yards into the empty net. McIntosh made it five and then scored the sixth.
