May, 21, made sure of the points when he curled the ball in from 20 yards three minutes later to take the Perth side into the top half of the table and not for the first time this season, the Northern Irishman addressed speculation about the player's future.
"It was a great finish," said Wright. "Stevie is having an excellent season and I am delighted with that.
"He can play at the highest level but there is a lot of work to be done.
"If someone comes in and makes the right offer, that's football, he will be gone and we have to move on. But I keep emphasising the point, he doesn't want to leave, he wants to stay for the full season.
"It is his first full season - I know he has had loan spells at Hamilton and Alloa - and we are going for top six, he is playing every week, we have a League Cup semi-final to look forward to, we have the Scottish Cup to look forward to, he has a lot to play for this season and he will develop by continually playing.
"The worry for Stevie if he moves is that he stops playing, or plays a bit part for the next six to 18 months.
"It will take an exceptional offer for him and with performances like that the price will be going up and up anyway."
A dejected Buddies boss Danny Lennon left his players in no doubt about his disappointment after the game and admitted the Paisley fans "deserve better" from his side.
"There was a massive incentive to jump a place in the league today and we failed to take that," he said.
"I was straight to the point with the players. You have to defend.
"Regardless of how poorly you are playing, you are hoping a clean sheet at least gets you a point but we are looking vulnerable at the back.
"Only when we are up against the odds do we come out and produce but any time there seems to be a little bit of light (we don't).
"That has happened at our football club for a generation now.
"I look at the League Cup success we had last year and the teams we put out, Aberdeen, Celtic, and going on to win it against Hearts.
"We were up against it for 20 minutes in the final and the players see it slipping away from them and they know that it's do or die and they seem to produce.
"We have 17 (league) games to go, what are we going to do, wait until the last five games until we have to start to huff and puff and fight for things?
"Our fans deserve better than that, for what they invest emotionally, financially and with their time, they deserve more."
