Reynolds returns to haunt Well
Mark Reynolds scored against his former club as Aberdeen came from behind to win 3-1 and end a near five-year wait for a league victory over Motherwell.
Reynolds headed Aberdeen in front in the 76th minute in between Niall McGinn's second-half penalty double as the Dons bounced back from Henri Anier's first-minute opener at Fir Park.
The visitors also hit the bar twice against a Motherwell side who looked flat following their Europa League exit in Russia in midweek.
Aberdeen's win over last season's runners-up builds on their opening Scottish Premiership victory over Kilmarnock and is a sign of real promise that they can mount a challenge in the top half of the table after four years in the bottom six.
The Dons were ultimately convincing winners against a side they had not beaten in 15 league games since a 2-0 win under Jimmy Calderwood in November 2008.
Both Mark McGhee and Craig Brown failed to take three points against their former club, although the latter enjoyed two cup wins, but it was first-time success for Derek McInnes, who stretched his unbeaten run as Dons boss to seven games.
The game did not start with such promise for Aberdeen and their official travelling support of 1,879, who were silenced with 40 seconds gone. John Sutton found Anier and the Estonian showed real composure as he waited for Jamie Langfield to go down stroking the ball over him and inside the near post.
Aberdeen, who were without the injured Barry Robson, had two chances to level inside 10 minutes. McGinn had the first when he was played down the right channel by Willo Flood but Lee Hollis got down to block the shot.
Peter Pawlett created another opportunity in the same area when he skinned Stephen McManus but his shot bounced off the bar.
The visitors hit the bar again in the 29th minute when Calvin Zola sidestepped McManus on the right edge of the penalty area and curled the ball over Hollis.
Zola had an ideal chance to level two minutes after the restart when Flood set him up in space 14 yards out following another counter-attack but the summer signing from Burton completely missed his kick.
Zola had another chance when a Jonny Hayes cross fell for him beyond the back post but he fell back as he shot wide.
But their equaliser soon came in the 62nd minute following some poor play in the Motherwell defence. StevieHammell was in yards of space as he tried to bring down Clark Robertson's high diagonal ball just inside his box but he miscontrolled and Hayes burst on to it and ran at McManus.
The Scotland defender dived in and brought the Irishman down before McGinn sent Hollis the wrong way from the spot.
Aberdeen continued to look the better side and took the lead after McManus had been penalised for a push on Josh Magennis. Reynolds broke free from his marker to powerfully head home Hayes' free-kick.
Hollis saved with his legs from Magennis after McGinn's cutback and John Beaton pointed to the spot from the resulting corner, although the infringement was not obvious. McGinn found the same corner with his 84th-minute effort.
