Makeshift midfielder Zak Vyner netted as an injury-hit Aberdeen side won 3-0 at Motherwell.
Derek McInnes named six defenders in his line-up after being hit by a shortage of fit central midfielders but Vyner and Greg Leigh both made key contributions going forward after being handed unfamiliar roles in the middle of the park.
Joe Lewis’ early penalty save from James Scott gave Aberdeen the platform and striker Sam Cosgrove opened the scoring in the 15th minute with an exquisite finish while Motherwell were briefly down to 10 men.
Niall McGinn exploited slack play to double Aberdeen’s lead in the 53rd minute and Vyner fired home the second goal of his career on the hour mark.
Aberdeen’s first win in four matches, which moved them a point off third-placed Motherwell in the Ladbrokes Premiership, was a triumph in adversity.
McInnes had admitted that Dean Campbell was the only natural midfielder available but started with the teenager on the bench following his part in Scotland Under-19s’ midweek victory over their German counterparts.
Lewis had already foiled Scott before the fifth-minute penalty, which the goalkeeper conceded when he tried to deal with Shay Logan’s short pass-back. Christopher Long nipped in front of Lewis and went down with referee Euan Anderson immediately pointing to the spot despite protests from the Dons man.
Lewis produced his second penalty save of the season when he threw up his left hand to divert the ball over after Scott had shot to the keeper’s right.
Barry Maguire temporarily dropped into the back four but was fooled by Leigh’s through ball after the stand-in midfielder dispossessed Long 15 yards inside the Aberdeen half. Cosgrove raced forward and chipped Mark Gillespie from inside the box.
Aberdeen’s second goal was also the result of Motherwell losing the ball, this time not far from the edge of their own box. McGinn took the ball off Allan Campbell, took a couple of strides forward and lofted a shot into the far corner of the net.
