The Owls Under-18s impressed in a pre-season friendly at Scunthorpe last Friday.
The warm-up fixture against the Iron saw Wednesday score three outstanding first half goals with just one in reply from Scunthorpe after the break.
Joe West broke the deadlock with an unstoppable strike into the top corner from 25 yards.
Marcello Benedetti doubled the lead with a sweet angled hit from the left before Wednesday wrapped up the game before the break with an eye-catching third from Layton Swaine, involving patient build-up from the visitors.
Scunthorpe pulled a goal back after the break through David Allasan and the goals are available to watch above.
The Owls are next in action away at Sunderland on Wednesday (12.30pm).
