HAWICK appear to have been blinded by northern lights on Saturday after letting their half-time lead at Rubislaw slip to a home victory.
Aberdeen had seemed livelier in the opening stages of the RBS Premiership clash with winger Erland Oag showing pace to touch down for the opening try with Mark Ryan converting.
Neil Renwick responded with a penalty before Grammar scored again through prop Stuart Cessford after some poor tacking from the visitors.
However, the Greens came to life and a fine try by Shawn Muir, converted by Renwick, closed the gap before allocated player James Johnstone chipped through for Renwick to touch down.
Ryan kicked a penalty for the home team to level the scores but, just before half time, Greens flanker, Johnstone again showed great pace to score a try which Renwick converted to give the visitors a 22-15 half time lead.
After the restart, Aberdeen came out the livelier side and scored almost immediately through their very handy Kiwi No 8 Tom Preece, with Ryan converting. Hawick appeared to crumble as man of the match Preece created an opportunity for Calum Gordon to add another try before scoring himself.
