The decisive goal in a match which the visitors thoroughly deserved to win came with seven minutes left when a corner was headed home by substitute Scott CRABBE.
The defeat means the Dons miss out on a money spinning tie with Peterhead and the chance of a bumper semi-final pay day at Hampden. However, it would have been a traversty if the SPL side had won this match as not one of the players on show played anything like the levels they are capable of.
