The Owls Under-18s swept aside a lacklustre Leicester in the Midlands on Saturday and emerged with a comfortable 3-1 victory.
An Emmanuel Dieseruvwe strike and two own goals were enough for Wednesday, although the home side did grab a consolation deep into added time through Louis Tambini.
After a cagey opening, Charlie Dawes had the first meaningful effort on goal, but his right-footed strike flashed just wide of the post.
The Owls took the lead just after 20 minutes, as some neat footwork by Jack Taylor preceded a feed to Dieseruvwe on the edge of the box, who curled a shot into the far corner.
The visitors dominated the rest of the half, and had a number of chances to extend their lead.
First, the lively Dawes muscled his way in to the box but was denied by Blues keeper Josh Smith.
Defender Elias Moses then came close as his long range drive deflected wide of the upright.
Wednesday did extend their lead on the half hour, though, when a Dawes corner was headed in to his own net by Luke Downes.
The floodgates threatened to open for the home side, but Smith was once again on hand to deny Dawes from close range.
Branden Fox almost hauled Leicester back in to the game but his 25-yard bullet rattled off the Owls crossbar.
The match was all but settled early in the second half as a clearance by Owls’ keeper Cameron Dawson caused confusion in the Leicester backline and Recce Awuah could only nod the ball past the onrushing Smith into his own net.
Tambini did pull a goal back for the home side deep into stoppage time, but the damage was already done and Wednesday returned to Middlewood Road with all three points.
“After the first ten minutes we settled down and started to control the game in and out of possession,” said academy coach Max Wragg.
“The lads got themselves in to great positions and we were definitely the better team. We probably deserved a bit of luck with the own goals.
“We were disappointed to concede in the last minute, but that's what can happen if you switch off for a second.
“We'll take the shape and confidence from this match into the Sheffield United game and hopefully we can get a result like we did today.”
