JOE LEWIS: First real involvement was to pluck a cross out of the air after 36 minutes then made the save of the half with his legs to deny Jai Quitongo the opening goal. A few more worrying moments in the second half but earned his clean sheet. 6

SHAY LOGAN: Given license to push forward regularly in the first half given how little defending he was required to do. Bit busier in the second period but handled it comfortably. 6

MARK REYNOLDS: Kept busy by the ever-dangerous Quitongo and mistake let the striker in for Morton’s first chance of the game late in the first half. A few awkward moments in the second period but did just about enough. 5

ANTHONY O’CONNOR: Similarly put under pressure by Morton during a second-half spell while his header from one of Aberdeen’s many first-half corners looped over the top. 6

ANDREW CONSIDINE: Not a full-back ever likely to charge up and down the wing but was solid enough and got up the park on occasion, too. Clever header across goal also gave him an assist for Aberdeen’s first goal before being booked late in the game. 6

GRAEME SHINNIE: Usual industrious performance in front of the Aberdeen defence but also willing to push forward whenever space opened up. Put in a terrific cross for the first goal then had a chance of his own moments later but thrashed his effort off target. 7

NIALL MCGINN: A perennially busy and effective presence down Aberdeen’s right. Pulled a first-half volley off target then was booked early in the second period for simulation. Late goalbound stab well saved before setting up McLean for the second. 7

JAMES MADDISON: Posed a regular threat from dead balls, although should have done better with one first-half chance from open play than pull it wide of target. Linked play well between midfield and attack. 7

KENNY MCLEAN: Former St Mirren man sealed the win with Aberdeen’s second late in the game. Had also come close to giving his team an early lead with a near-post flick that was well saved by the goalkeeper, while a later effort sailed narrowly off target. 7

JONNY HAYES: Unfortunate to see an early header strike the crossbar. Drifted in and out the game after that but his pace meant he remained a threat on the counter. 6

ADAM ROONEY: The goalscoring hero once again, his well-placed header enough to end Morton’s resistance and pave the way for an Aberdeen victory. Had been quiet in the first half before a late header crashed against the crossbar. 7
