Aberdeen failed to maintain their momentum of Wednesday’s win at Rangers by crashing to a 2-0 loss to St Johnstone.
The Dons lack of cutting edge in attack was a major contributing factor to this home loss.
Having gone into the game on a high after the 1-0 defeat of Rangers in Glasgow the Dons never came close to reached the levels or intensity of Ibrox.
Saints punished that with two second half goals with Joe Shaughnessy and Blair Alston finding the net.
Aberdeen created the first opportunity in the ninth minute when Connor McLennan threaded through a pass to release Stevie May into Saints’ penalty area.
The striker flashed a low shot across the face of goal that went inches wide with Lewis Ferguson racing to try and get on the end of it.
In the 19th minute Dons skipper Graeme Shinnie tried his luck from 30 yards with a low, speculative shot that went well wide.
Keeper Joe Lewis produced a superb save in the 25th minute at his near post to beat behind a vicious drive from the right edge of the penalty box from Matty Kennedy.
In the 34th minute Scotland international centre-back Scott McKenna picked up possession on the half-way line and was allowed to progress upfield unchallenged.
It was reminiscent of his memorable 40 yard screamer in the 3-1 defeat of Kilmarnock in January. With that in mind the Red Army shouted ‘shoot’.
As Saints backed off McKenna obliged but his powerful 35 yard drive flew just over.
Moments later the impressive Max Lowe went on a rampaging run up the left flank where he alluded two challenges before delivering a superb cross along the face of goal but there were no Dons in position to capitalize.
Aberdeen came close in the 44th minute when McKenna met a corner and headed towards the far corner but keeper Zander Clark dived to block.
In the 55th minute teenager Connor McLennan drilled in a low shot from 22 yards out but it was straight at Zander Clark who got down quickly to smother the effort.
Moments later McLennan again shot from range but his effort went over.
In the 62nd minute Ferguson cut inside and unleashed a curling 20 yard shot that Clark blocked but spilled.
The loose ball was cleared before Aberdeen could capitalize.
St Johnstone went ahead in the 70th minute direct from a corner kick.
Former Dons defender Joe SHAUGHNESSY rose up to meet the delivery and directed a bullet header beyond Joe Lewis from 12 yards.
Moments later Matty Kennedy went down from a challenge by Max Lowe in the box. Saints called for a penalty but referee Don Robertson waved play on.
In a disastrous few minutes for the Reds they went further behind when substitute Blair ALSTON curled a superb 25 yard drive beyond Lewis to make it 2-0 in the 73rd minute.
Substitute Niall McGinn came close with a 25 yard free kick that was saved.
