Stevie Campbell's side went down to the only goal of the game at McDiarmid Park tonight in their first ever Under 20 fixture.
And for what was a much younger United side it was a hard introduction to the life in this new league, particularly as they were up against a much more experienced home side.
Though the game was decided by a bizarre goal early in the second half when keeper Phil Anderson's clearance was charged down and into the net, there could be no complaints about the outcome with Saints dominating most of the game.
