Aberdeen spurn chance to go to third place
The Dons had the best of an uninspiring first half but missed a couple of chances through strikers Darren Mackie and Richard Foster.
There was little between the teams in the second period and almost no goalmouth incidents and a point apiece was all either side deserved.
Right at the death McDonald could have grabbed the points for the home side but hit a weak shot from eight yards out straight at the grateful Esson. It was that kind of game.
