St Mirren warmed up for their Premiership relegation play-off tie against Partick Thistle with a 1-1 draw at home to Dundee United.
Craig McLeish's side were hoping to build on their midweek victory against Aberdeen ahead of the first leg at Firhill on Thursday night.
But they had to settle for a point after Jake Young's second-half strike cancelled out a first-half opener from Zac Sapsford for a United side already confirmed in seventh place prior to the match.
St Mirren made five changes from their win at Pittodrie including handing a first start to 16-year-old Luke Douglas. Jayden Richardson, Scott Tanser, Roland Idowu and Young also came in, with Liam Donnelly, Richard King, Jacob Devaney, Killian Phillips and Mikael Mandron dropping to the bench.
United gave a debut to 17-year-old Keir Gilligan as one of four changes following their goalless draw with Livingston. Kristian Keresztes, Craig Sibbald and Max Watters were also added to the line-up in place of Bert Esselink, Johnny Russell, Will Ferry and Neil Farrugia.
The first chance of the game went to Douglas, who was played in by Idowu but saw his driven effort saved by Dave Richards. The United goalkeeper then did well to repel Richardson's follow-up attempt.
There was a let-off for Richards when he spilled Douglas' shot over the line but his blushes were spared by the subsequent offside call. Sam Cleall-Harding then became the first player booked when he went in late on Douglas, who looked lively on his full debut.
It was United, though, who opened the scoring after 27 minutes. Watters supplied the cross from the left and Sapsford flicked the ball beyond Ross Sinclair from close range. Sibbald then blazed a shot over the crossbar from outside the box before Alex Gogic came close at the other end with a ferocious drive that was well saved.
Vicko Sevelj almost extended the visitors' lead early in the second half with a header from a corner that was pushed away by Sinclair. At the other end, Douglas failed to hit the target after being teed up by Marcus Fraser then saw a curled effort well saved by the goalkeeper.
St Mirren, though, did draw level in the 70th minute. King played in Young and his shot sped past Richards with the aid of a heavy deflection.
Saints could have won it late on but debutant Thomas Falconer's shot struck the post and an overhead kick from Gogic was blocked.
