Joey Dawson got the only goal of the game, as the Iron's Under-18s side got their season off to a perfect start with a win at home to Doncaster Rovers.
He netted six minutes from time to give the side all three points in the Youth Alliance North East Conference in what was the side's first match in 189 days.
The performance was a largely dominant one against last year's Champions, but United were almost made to rue missed chances with 10 minutes to go when a penalty was awarded to Doncaster. Thankfully for Scunthorpe, that kick hit the upright and cannoned back into play.
The Iron started brightly and competed well in the opening period, creating numerous chances, while defending resolutely at the other end, restricting Rovers to only a select few efforts on goal.
Dawson and Cameron Wilson continually combined well in the opening exchanges as they looked to get in behind the Doncaster defence, but the duo were unable to make their early exchanges pay.
United had four clear-cut opportunities in the first half which saw the home side go through one-on-one, with the only disappointment following the good build-up play being the chances weren't taken and the two sides went in level at the interval.
Scunthorpe continued the second half in the same manner, dominating the early exchanges.
Alex Wilkinson had one of the best chances of the game, connecting well to a Harry Baker cross to head just wide of the far post, with United looking to make one of their chances count in the second period.
Fellow second-year scholar Patrick Virgo also had an impressive display in the heart of the Iron midfield, breaking the lines on a number of occasions before two opportunities were presented to him. On both occasions, the Doncaster goalkeeper made good saves to thwart him.
Dawson was next to have a couple of opportunities, first turning and firing goalwards before another header went narrowly wide, this time just past the near post.
In the 80th minute, after all the dominance, the visitors were awarded a penalty at the other end with Dan Gallimore adjudged to have fouled with a trailing leg, despite the midfielder pulling out of the challenge. The Rovers player hit the deck, with referee Waqar Ahmad pointing to the spot.
Goalkeeper Jake Balme went the right way from the resultant kick, but despite the effort being beyond him, the ball rebounded back into play off the post.
United's only change came just after with Jake Moore-Billam replacing Wilson and just two minutes later the match winner was netted.
The goal came from route one, with Balme sending a goal kick long. Dawson gambled on a flick which was forthcoming and he kept his composure to slot beneath the Rovers 'keeper to win the game with six minutes left.
Professional Phase Development Coach Steve Thornber said: "It was a very good team performance. We dominated large parts of the game against a Doncaster team who won the game last season.
"On overall play, it was a well-deserved victory and a very pleasing performance. It was nice to see that the lads had taken on board the work that we'd done defensively and offensively following our game last week.
"We've got a small squad this season with a couple of injuries, so it was also a good opportunity to bring through Harvey Cribb from the Under-15s and Owen Foster from the Under-16s, who were both on the bench. We didn't get them on the pitch, but it's a great experience for them to be around the Under-18s set-up."
