The points were shared at Middlewood as Wednesday scored late to deny Wigan the chance to go top of the league.
A stunning 86th minute goal from Paulo Aguas rescued a deserved point for the Owls following a headed strike by Wigan’s Tom Costello.
The match started as an even affair in midfield with neither side having the guile or time of possession to create meaningful chances.
Wednesday had the early openings but hit three quickire efforts over the crossbar.
The highlight of the first half was a bustling run from right wing back Basille Zottos, using skill, pace, and tenacity to drive into the box before finding Aguas, who saw his cross headed into the grateful arms of Wigan goalkeeper Owen Mooney.
It took the visitors 57 minutes to test Wednesday keeper Alex Hare as he tipped a long-ranger around the post – but the subsequent corner led to the Latics taking the lead as Sean McGurk crossed expertly to Costello, who headed home with force.
McGurk attempted to add a goal to his assist as he intricately dribbled into the penalty area but maintained the theme of the game by blazing his chance over the bar.
The visitors almost put the game to bed in the 81st minute following a swift counter.
McGurk’s shot was brilliantly saved by Hare and the follow up header from Costello was valiantly cleared off the line by captain Luke Yates.
Wednesday finally had their goal as the energetic Luke Hall drove into the box and gave the ball to Aguas, who used trickery to dumbfound the defender before placing his shot into the bottom corner.
The final few minutes were enthralling as both sides went for the win.
In added time, Wigan constructed a quick counter attack which ultimately struck the post and was cleared from the box in frantic fashion.
The Owls now face Barnsley at home this Saturday with the Tykes sitting in second place.
