The Dons once again proved too strong for St Mirren as they scored four goals against the Paisley side for the second time this season and with it go into the international break with three valuable points.
First competitive Dons goals from Max Lowe, youngster Connor McLennan and a Sam Cosgrove brace proved too strong for The Buddies, the victory lifting The Dons back into the top six.
Derek McInnes was forced into making four changes from the side that lost 1-0 away at Celtic Park. Wilson, McGinn and May were all absent from the squad due to injuries along with Scott McKenna who missed out through suspension. Max Lowe, Sam Cosgrove and Lewis Ferguson all returned to the starting XI, along with Connor McLennan who was given his first start for The Dons only a day after his 19th birthday.
This was the second time St Mirren had travelled to Pittodrie this season - the previous outing ending in a resounding 4-1 victory for Aberdeen in the league cup. The visitors came into the game in much need of a win, having gone 6 games without a victory prior to this tie, scoring only one goal in the process.
Both teams started fairly well in the opening exchanges. Connor McLennan did well down the left-hand side to win an early corner for The Dons which eventually came to nothing after referee Alan Muir blew for a foul on a St Mirren jersey. Simeon Jackson had the first real effort of the game just before the ten-minute mark for the visors. Dons winger GMS was caught in possession inside his own half which allowed Jackson to latch onto the loose ball and get his shot away. His effort was hit with venom, but it sailed straight past the near post and did not trouble Joe Lewis. Aberdeen were enjoying the lion's share of possession throughout the opening stages, but St Mirren's 4-4-2 formation looked as though it could be tough to break down.
Aberdeen nearly opened the scoring after Max Lowe's miss-hit shot deflected off Cosgrove and wrong-footed St Mirren keeper Craig Samson, unfortunately for the Dons the ball rolled agonisingly past the far post and the tie remained goalless. GMS was on target twice the last time the sides met and the winger looked to continue his excellent form from the outset, cutting inside and firing a shot inches wide of the post again. A goal looked as though it was coming and on 26 minutes it eventually did courtesy of a brilliant diving header from Sam Cosgrove - his first competitive goal for The Dons. GMS and Logan combined nicely down the right-hand side before the latter deliver an excellent in-swinging ball towards Cosgrove. The Dons striker did well to adjust his body position and get his head under the ball and make a decent connection to fire past Samson who had no chance.
Aberdeen looked in the mood and nearly doubled their advantage moments later on the counter-attack. Lewis did well to pick out McLennan down the left-hand side. The youngster did well to get his head up and find GMS on the opposite wing. Mackay-Steven's first touch was perfect shifting the ball onto his left foot before curling an effort straight back off Samson's far post. 30 seconds later Samson was picking the ball out of his net for the second time this afternoon after Connor McLennan's magnificent strike from the edge of the area. Celebrating his first start for The Dons, McLennan latched onto a lay-off from Shinnie and despite being off balance the youngster managed to swing his right foot at it and connected sweetly, the ball flying past Samson and cannoning in off the same post GMS hit seconds before.
The Dons were on easy street and Max Lowe made it 3-0 five minutes before the break. After some patient build-up in which Lowe played a big part in, The Dons got a slice of luck when GMS' shot ricocheted off two St Mirren bodies before dropping at the feet off Lowe. In acres of space and only 10 yards out Lowe made no mistake and calmly slotted past Samson to become the third player of the day to open their goal scoring account for the club.
It should've been four when Graeme Shinnie was played through on goal, clearly being impeded the Aberdeen captain went down in the area but Alan Muir deemed the challenge acceptable and waved away the claims.
On the stroke of half time Paul McGinn deservedly went into the book for a rash, late challenge on Ferguson.
Half-Time Aberdeen 3-0 St Mirren
Out came the teams for the second half, The Dons looking to add to their first-half goal tally. McLennan looked lively down the left-hand side.
St Mirren nearly had a lifeline in freakish circumstances after Jackson closed down Lewis' clearance. The ball spun up and over Lewis who did well to scramble back and claw the ball back off his line to spare his blushes. Unfortunately, McLennan's dream start was brought to a premature end after he took a sore one to the shoulder and was forced off with Chris Forrester replacing him. St Mirren were playing with a little more confidence and nearly got back into the tie after Hodgson took advantage of a Shay Logan slip in the penalty area. However, his curling effort failed to trouble Lewis - a real let-off for The Dons.
Just as St Mirren looked to pose a threat Cosgrove made it 4-0 after 65 minutes and put the game beyond all doubt. Max Lowe did brilliantly down the left-hand side, cutting inside with a cheeky nutmeg. The left-back got his head up and picked out Cosgrove who's first time left-footed effort had to much power for Samson who couldn't keep it out.
With twenty minutes left to play Stephen Gleeson came on for Dom Ball in the middle of the park. St Mirren did get a consolation goal with fifteen minutes left to play. A slack pass from the substitute Gleeson was capitalised on by Cammy Smith who played in the unmarked Jackson, who calmly dinked over Lewis to deny the Aberdeen keeper a clean sheet on his 31st birthday.
Cosgrove made way for Bruce Anderson in the final ten minutes, received a deserved standing ovation for his two goals and all-round excellent performance from the 14,003 fans inside Pittodrie. GMS nearly added a fifth in injury time, after some good link-up play with Gleeson in the middle of the park. The Dons carved open the St Mirren defence but Mackay-Steven's, who probably deserved a goal, finish lacked conviction and was comfortably saved.
That was the last action of note in the second half before the referee called a halt on the game, The Dons running out comfortable 4-1 winners. It will be a busy period after the international with the visit to Tynecastle before the Semi-Final at Hampden.
