Meanwhile, the visitors are looking to end a dismal campaign on a high, and victory on Wednesday evening has the potential to catapult them as high as eighth spot.
While St Johnstone already know that they still have plenty of work ahead of them to avoid relegation, they may at least enjoy a positive moment over the next couple of days.
If Dundee fail to defeat Hibernian on Tuesday night, St Johnstone will be safe from ending the campaign in last place, sending the Saints into a relegation playoff instead.
That will bring its own pressures to Callum Davidson and his squad, but it is the best-case and most likely scenario and one which they should start preparing for sooner rather than later.
All things considered, Davidson can be satisfied with his team's recent form, just two defeats coming in seven games with one of them being at Celtic.
Last time out, St Johnstone were only denied victory at seventh-placed Livingston courtesy of a last-minute goal, but it remained an important point to keep the pressure on Dundee.
Jim Goodwin has not found it easy to get improvements out of an Aberdeen squad who were already consistently under-performing prior to his arrival.
However, while his overall record reads two wins from 10 games, the 40-year-old has collected a much-needed eight points from the most recent six games.
On the back of edging out Dundee, the Dons earned a 1-1 draw at Hibernian on Saturday, although there was a tinge of disappointment having held a lead at Easter Road.
At this stage, preparations are already underway ahead of next season, but the target remains on avoiding a 10th-placed finish, which would represent their lowest spot since 2003-04.
Depending on how Dundee fare 24 hours earlier, Davidson may opt to make further changes if he is able to rest some of his regular players.
Goodwin has openly revealed that he intends to only start players who are under contract for next season or may still have a future at Aberdeen.
With that in mind, it would come as no surprise if the starting lineup remained the same from the Hibs draw, Goodwin having revealed that he had been pleased with the opening 45 minutes before making numerous changes after the break.
St Johnstone possible starting lineup:
Clark; Cleary, Gordon, McCart; Rooney, Hallberg, Davidson, Booth; MacPherson; Middleton, Hendry
Aberdeen possible starting lineup:
Lewis; McCrorie, Gallagher, Bates, MacKenzie; Barron, Ferguson; Hayes, Polvara, Besuijen; Watkins
We say: St Johnstone 1-2 Aberdeen
With neither team being able to boast being in decent form, this could turn out to be a hard-fought contest decided by desire over quality. Much will depend on how Dundee fare on Tuesday, but we still feel that Aberdeen will have enough quality in the final third to edge this fixture by the odd goal in three.
