Bruno Fernandes scored a first half double to help steer the Owls to victory over Wigan at Middlewood Road on Friday lunchtime.
Jakma Mohamed gave the Latics an early lead but Wednesday turned the game around before the interval to seal a 2-1 win.
It was difficult conditions for both sides with swirling winds affecting the play and it proved a factor in the opening goal.
A dangerous inswinging corner, made more so by the conditions, was finished from close range by Mohamed.
Disappointed by the manner of the goal, Wednesday dusted themselves down and gained a strong foothold in the game as they searched for a way back.
Reece Johnson went close with a powerful strike from Harris Lihe’s cutback but for all the positive play going forward, the equaliser was route one at its best.
Goalkeeper Logan Stretch sent a long punt upfield and Fernandes muscled off his marker before applying a confident finish.
Mohamed threatened to regain Wigan’s advantage but was denied by a good save from Stretch before Wednesday took charge of the contest on the half-hour mark.
Carlos Rodrigues did well to pick out Devlan Moses in the box but goalkeeper Jake Spaven made an impressive save. It mattered not, though, as moments later the ball was in the back of the net.
As the visitors sought to play out from the back, Wednesday’s press was effective, and Fernandes nipped in to round the goalkeeper and slot home his and the Owls’ second goal.
It was more of the same after the break with the hosts largely in control.
Moses fired a volley over the bar after a superb passage of play involving Jarvis Thornton, Sutura Kakay and Lihe down the left flank.
Northern Ireland youth international Moses was again denied on the half volley by a smart save before Stretch was forced into action to preserve the advantage.
Midway through the second period, Harrison Bettoni nodded a free-kick back into the middle where Cole Simms fashioned a strike on target but Stretch was well-positioned to make the save.
Set pieces looked the most likely route back into the game for Wigan, underlined by two free-kicks from wide areas that had hearts racing in the Owls’ 18-yard box.
First, Latics defender James Knott saw his goalbound header saved and then two minutes from time, Eko Solomon’s looping effort was tipped onto the woodwork by the young Owls shot-stopper and cleared to safety.
On a hat-trick, Fernandes had his moment to well and truly wrap up the game after gaining a yard of space down the left but dragged his shot wide of the far post.
A solid run out for the Owls youngsters who, on balance, deserved the points from the S6 clash and are next in action on Saturday week at home to Coventry.
