Tommy Wright fielded Liam Craig and Rhys McCabe as the McDiarmid Park outfit attempted to shake off their European malaise with a 0-0 draw against Real Sociedad.
Former Saints favourite Craig, who was released by Hibernian during the close season, played the full 90 minutes and was arguably the stand-out performer at Bayview.
He almost set up the opener for Joe Shaughnessy after just six minutes and coming close to breaking the deadlock himself after the interval.
Rhys McCabe has also been training with the Perth outfit in recent days as he looks to revitalise a career which appeared so promising when he burst on to the scene at Rangers.
The 22-year-old did little wrong during his 60-minute outing, displaying a good work ethic as the deepest man in midfield and showing composure in possession.
St Johnstone’s third recent trialist Jim McAlister, however, opted not to play in the fixture.
And no one could find the inspiration to find a decisive goal as St Johnstone’s bid to pick up the pieces from their miserable Europa League exit against Alashkert began with a 0-0 stalemate.
Saints boss Wright said: “I thought Rhys and Liam did well, but there’s been no movement in terms of bringing them in.
“We’ll continue to look at players, not only the players we have on trial.
“We are monitoring few things.
“Jim (McAlister) thought it wasn’t the best thing for him to play in the game, which is understandable.”
The ‘home’ side were a whisker away from claiming the lead with just six minutes on the clock, however Joe Shaughnessy couldn’t find the net with a header from Craig’s superb corner.
With two competitive, albeit ill-fated, matches under their belt, St Johnstone were visibly sharper than the Spaniards, however Mikel Oyarzabal flashed a dangerous shot across the face of goal midway through the first half.
With half-time approaching, Chris Millar, captaining the Saints, stung the palms of visiting goalkeeper Ander Bardaji with a drive form distance.
Esteban Granero, a player who boasts more than 70 first-team matches for Real Madrid, entered the fray in the second period, while St Johnstone introduced Chris Kane in place of Michael O’Halloran.
However, it was Craig who continued to prove the creative hub for Wright’s men, fizzing a ferocious drive just over the bar with 50 minutes on the clock.
With a customary deluge of substitutions on the hour-mark, any semblance of flow in the contest was lost, however Aritz Elustondo did curl an effort just wide of the post.
The Saints almost pinched victory in the dying embers but Kane saw his low shot from the edge of the box drift just wide of the post.
Wright added: “It was important we didn’t pick up any injuries and we gave the young players some game time, so we can be very pleased.”
