The Owls Under-18s sealed a thrilling 4-3 win over Nottingham Forest on Saturday at Middlewood Road.
Dan Wallis was the hero, saving a last minute spot kick as goals from Jordan Lonchar, Fraser Preston (2) and Liam Waldock proved enough for Wednesday.
Lonchar broke the deadlock from the penalty spot inside the first ten minutes and it was 2-0 before the half hour mark when Preston’s deep free kick crept in at the back post, after rebounding off Forest goalkeeper Jordan Wright.
The visitors halved the deficit before the break through Charlie Jemson’s towering header and almost drew level after the restart but for a fine Wallis save to deny Virgil Gomis from close range.
Waldock regained the Owls’ two-goal lead with an accomplished finish into the top corner but Forest came again as Jemson glanced home to claim his second goal of the game.
Preston’s hard work in the final third was then rewarded, as the youngster capitalised on a mix-up at the back to slot home, making it 4-2 with 15 minutes remaining.
But there was more drama to come as Gomis sprung the offside trap from a long punt forward and finished neatly past Wallis to set up a tense finish.
Gomis then saw his thunderous hit from 20 yards come crashing back off the crossbar before the visitors were awarded a penalty at the last.
But the Reds could not complete their comeback as Wallis saved Gomis’ spot kick for Wednesday to register a memorable victory.
