The Dons lined up in a 3-5-2 system with Diamond, Anderson and McGuire the back three and Tosh and Morrison operating as wingbacks, but it was Montrose who carved out the first chance of the match when Sharp hit a decent shot straight at Esson. Three minutes later Aberdeen went close when Craig held the ball up well before setting up Tosh. The midfielder hit a low shot from the edge of the area that was well held by Butler. Adams then went close in the 10th minute with a looping header that went over the bar. Four minutes later Scott Severin found Morrison with a great pass. The wingback fired in a low shot that was well held by Butler, but he might have been better with a cut back as he had good support.
Aberdeen were finally beginning to put some decent passages of play together and their pressure forced a couple of corners. Then in the 42nd minute the ball broke to Morrison and he hit a rocket shot that came crashing off the crossbar with Butler beaten. Montrose posted a warning that they were still a danger when Esson had to look lively a minute later to deny Smart. In the final minute of the half Aberdeen went route one and found Foster, but Montrose defended well and cleared the danger.
Tosh sent in a telling cross on the hour mark and Adams almost added to his tally as his header went inches over. Three minutes later Montrose went close again when their man of the match, Graeme Sharp, sent in a cross that beat the defenders and was thankfully gathered by Esson before the Montrose attack could react. The Dons grabbed the lead a minute later when a long ball from defence was skilfully controlled by Craig and thumped past Butler to cheer the Dons supporters in the 1,750 crowd. In the 70th minute Smart fired over for the home side before an Adams free kick was well blocked by the Montrose keeper.
The third goal came in the 78th minute when Heikkinen won the ball deep and released Tiernan. Adams met his cross glanced the header out of the reach of the keeper. Stewart replaced Foster in the 79th minute and made an immediate impact with a powerful run down the left. Unfortunately play was halted as Severin was adjudged to have committed a foul. Aberdeen added a fourth three minutes from time when the keeper misjudged a high ball and Craig pounced to score. Sheerin replaced Severin a minute with the game won.
