The Owls Under-21s posted a 2-1 victory over Crewe on Tuesday afternoon at Hillsborough.
Goals from Ryan Meadows and Tom Elliott ultimately sealed Wednesday’s maiden success on home soil this season.
Ryan Wintle impressively halved the deficit late in the game but it was too little, too late for the Railwaymen.
The first chance of note fell to the Owls on eight minutes as Darryl Lachman rose high in the box from Matt Penney’s corner but glanced wide.
Two minutes later, Crewe had the ball in the net through Joe Howell but the goal was ruled out for offside, while Jack Stobbs was proving a lively figure for the Owls at the other end.
The winger delivered dangerously from the right and the ball fell to Meadows, who saw his low shot saved.
Crewe then began to grow into the game and had good chances to edge ahead.
First, George Cooper hit a speculative effort from 40 yards that was deflected behind for a corner, from which Wintle saw his header from two yards impressively saved by Cameron Dawson.
Ten minutes before the break, the visitors were presented with a golden chance as the ball ricocheted through to Charlie Kirk, but Dawson was quick off his line and the Crewe man struck inches wide.
Then right on the stroke of half time, Wednesday pulled ahead. Stobbs delivered expertly for Meadows to power home his header from close range.
Wednesday began the second half at a higher tempo as Meadows hit over the top just after the restart.
Luke Booker was alert to clear off the line from Callum Ainley before Elliott gave Wednesday a two-goal cushion.
Stobbs whipped in another dangerous centre, Penney kept the ball alive at the back stick and as Perry Ng headed against his own crossbar, Elliott was on hand to prod home the rebound.
Wednesday began to turn the screw and Stobbs was harshly denied a penalty after being pulled to ground, following a neat piece of skill before Crewe pulled a goal back.
The ball fell to Wintle 25 yards from goal, who thumped in off the post with a ferocious first time strike.
Perry Ng then hit the crossbar at the last in a nervy moment for the Owls but the hosts held on to post a welcomed first win on home soil this season.
