Match ends, Aberdeen 2, Kilmarnock 1.
Aberdeen built on last weekend's League Cup success with a laboured victory against Kilmarnock in the Premiership.
Over 14,000 fans watched the Dons work hard for a follow-up win they so badly craved, despite an early setback when Kris Boyd struck for Killie.
Adam Rooney's seventh Aberdeen goal brought his team level and Niall McGinn twice failed to add to that soon after.
But Ryan Jack's low, steered finish in the 72nd minute brought the hosts their third win of the season over Killie.
It keeps Aberdeen in second place with a game-in-hand over Motherwell, who sit level on 57 points with Derek McInnes's men.
Kilmarnock's desire to increase the distance between them and the relegation play-off spot will have to wait another week, but Partick Thistle, Ross County and St Mirren all losing on Saturday is consolation for manager Allan Johnston
Aberdeen sent out injured duo Peter Pawlett and Jonny Hayes to stroll around the Pittodrie pitch holding the League Cup trophy five minutes before kick-off, but how McInnes and the home crowd wished the midfield pair could have stayed there once referee Craig Thomson blew his starting whistle.
Reliance on the creativity and attacking surges of Pawlett, in particular, has been heavy, while Hayes can also conjure up something out of nothing in the final third.
It was that section of the park that Kilmarnock's Rory McKenzie made a piercing, unchallenged run into to create the opening goal for Boyd.
The visitors' top marksman knew too well how much his low strike on the turn, which rolled painfully past a helpless Jamie Langfield, would deflate the home crowd and celebrated by holding hand over mouth to rub in his 19th of the season.
Cammy Smith immediately whizzed a 20-yard shot a foot wide of Killie goalkeeper Craig Samson's goal to suggest Aberdeen would not let the set-back bother them, and Rooney's subsequent equaliser confirmed it.
At the hub of its creation was Nicky Low, who along with Smith looked to deputise for the likes of Pawlett, Hayes and the benched Barry Robson. Low's exchange of passes with Rooney allowed the latter to spin and direct a low shot - and one not unlike Boyd's finish - into Samson's net.
From there, the hosts found some momentum and both Rooney and Smith took turns to provide McGinn with a couple of opportunities which the Northern Irishman turned over.
Killie's second-half offering amounted to one Boyd shot from distance which Langfield dealt with comfortably. It was in defence where the visitors were winning their stripes.
Vitalijs Maksimenko and Lee Ashcroft repelled what came into the box as a result of Aberdeen's dominant possession and the Dons opted to introduce Robson in search of the telling delivery that would make the difference.
That cross arrived, although from the unlikely boot of Mark Reynolds. His low ball from the bye-line at the left-hand side was completely missed by Smith but rolled on to Jack, who stroked it beyond Samson at the Beach End of Pittodrie.
Jack went on to carve another chance for McGinn, who poked wide to confirm it was not his day in front of goal.
