The young Dons got off to the perfect start when Stephen O'Neill crossed for Declan McManus to score in the first minute. Aberdeen then completely dominated the first 20 minutes and they should have scored more. Ryan Fraser, Cameron Smith and Jack Grimmer all had shot which went just wide.
Wingers Ryan Fraser and Stephen O'Neill were seeing plenty of the ball and put in some great crosses but the Dons strikers were struggling to get the better of a well organised Inverness defence.
Inverness, who are coached by former Dons legend Duncan Shearer, slowly got to grips with the game and Christie fired a shot just over. The same player forced Lukasik into a good save and then on the half hour mark they equalised. Aberdeen gave away a soft free kick and from about 30 yards Watson hit a superb dipping shot which gave Lukasik no chance.
Aberdeen then had more chances. Ryan Fraser crossed for McManus but his header was well saved. McManus then had the ball in the net but was ruled offside.
After the break the Dons took control of the game. Cameron Smith ran the show and Cammy could have had a number of goals. The former Scotland schoolboy hit the post straight after the restart. Ryan Fraser then went close after being set by Smith. Finally just before the hour mark Aberdeen regained the lead. Substitute Dean Carse did well on the break. He picked out Grimmer who played the ball for McManus. He crossed for Smith to fire home.
Ryan Fraser then went close again before Cameron Smith had a shot well saved by Baldy. Full back Jamie Masson made a brilliant mazy run from inside his own half. He beat everyone and was one on one with the keeper but his shot was straight at Baldy. Smith then went close again, although he might have been better squaring the ball to Carse who had taken up a great position. Jack Grimmer then had a shot tipped over by Baldy, who was single handily keeping his side in it. Aberdeen also should have had a penalty when Ryan Fraser was taken down in the box, although in fairness Inverness had a strong claim for a penalty in the first half.Inverness deserve credit for fighting to the end and punished Aberdeen for not taking their chances. The Dons defence failed to clear their lines and although Lukasik initially made a good save substitute Dingwall reacted quickest to place the ball into the empty net.
Aberdeen had one final chance when Fraser cross and after Baldy hesitated there was a stramash in the box but the ball was cleared to safety.
