Wednesday came from behind to beat Huddersfield 3-1 in a hard-fought derby clash as the Championship resumed following the international break.
A tepid first half gave way to a much improved second in which Sean Scannell gave the visitors the lead.
But a quick-fire double from substitute Lucas Joao and then Kieran Lee put the Owls in front and Joao applied the finishing touch in stoppage time.
The late drama was a world away from a bland start, with Ross Wallace the Owls’ most promising outlet in the early throes of a game that took a while to warm on a bitterly cold Sheffield afternoon.
The winger saw plenty of the ball and threaded one accurate feed through to Fernando Forestieri, whose diving header fell just wide.
Huddersfield offered little in response but when they did 20 minutes in, a long range drive from Scannell sent Keiren Westwood down smartly to save with his legs.
The pattern remained the same in a low key opening to a contest that certainly needed a spark after the break.
Joao was introduced for the resumption but it was Forestieri who caused a problem immediately after the whistle, pouncing on a loose Dean Whitehead backpass and forcing Joe Murphy into evasive action.
But on 54 minutes, Huddersfield scored against the run of play. Kyle Dempsey picked out Scannell with a curling cross and the former Palace man glanced a perfect header beyond Westwood.
The goal stirred Wednesday into life and they went close with an immediate response as a Wallace shot looked destined for the far corner but Whitehead was back on the line to clear.
The Owls ramped up the pressure – Lewis McGugan and Gary Hooper came on from the bench – and a fierce goalmouth scramble saw Atdhe Nuhiu go down in the area but the referee was unmoved.
Huddersfield broke in the next attack, though, and nearly put the game to bed but Westwood made a superb close range block from Emyr Huws.
Back came Wednesday and Hooper failed to get a connection on a Daniel Pudil cross before they finally got the breakthrough on 77 minutes.
Forestieri did wonderfully well to ghost down the left and shoot only for Dempsey to hoof off the line – but Joao was on hand to fire the rebound home.
Hooper then might have won it with a blistering drive that flew into the Kop but Lee went one better nine minutes from time.
Forestieri was again the architect and in similar fashion to the leveller. This time he was thwarted by Murphy but Lee was the man of the moment in the right place at the right time to stab into the back of the net.
Still there was time for more and in the third minute of stoppage time, Joao delivered a marvellous hit over and beyond the despairing Murphy to seal victory.
Wednesday: Westwood, Hunt, Loovens, Lees, Pudil, Wallace, Semedo (McGugan 67), Lee, Helan (Joao 46), Forestieri, Nuhiu (Hooper 72)
