After three minutes Aberdeen's Ferne Snoyl turned away from Jay Shields before smashing in a great shot which was deflected over his own cross bar by Chris Hogg.

Aberdeen thought they had made the game safe in the 86th minute. Kevin McNaughton picked out Lovell and the big striker's shot beat Malkowski but was cleared off the line by Gary Caldwell back into the arms of his keeper.
