Partick Thistle 0
Goal: Adam Rooney (34 pen).
Partick Thistle continued their poor record against Aberdeen in what turned out to be a fairly drab game with a first half penalty giving the visitors all three points.
And it was The Dons that started better with two goal chances in the first 10 minutes Thistle.
Thistle then missed a glorious chance to take a 10th minute lead when James Craigen shot wide of the Aberdeen goal.
A busy period followed for the Thistle goalkeeper Paul Gallacher who, following an Aberdeen free kick, was required to tip the ball round the post for a corner, though most people were anticipating a raised flag for offside.
That proved to be a controversial call as it was from the corner that followed that Aberdeen were awarded the penalty that would ultimately determine the outcome of the game; the ball striking the hand of Abdul Osman.
Gallacher has a good record of saving penalties but on this occasion, and despite diving the right way, he was beaten by Adam Rooney’s effort.
Aberdeen came close to a second goal just three minutes after taking the lead with Ryan Jack stinging the hands of Gallacher before the last event of note of the opening 45 minutes saw Thistle have their own appeal for a penalty for handball turned down.
The second half was a poor affair with Aberdeen happy to protect their lead rather than push for a second goal. However Gallacher was called into action again in he 73rd minute to prevent Rooney finding the net with a header.
Thistle pushed for the equaliser, but despite their pressure they did not have the cutting edge to finish.
