A Simon Cox strike early in the second half gave Nottingham Forest a travelling triumph at Hillsborough on Saturday.
A 4,000+ following from the Midlands made the short hop north to see the visitors improve on a run of just one win in seven games and saw exactly that.
Openings were few and far between in a tight contest with little between the teams and one moment of quality sealing the points.
The Owls had threatened first, though, when Atdhe Nuhiu thumped a header narrowly over the crossbar in front of the Kop.
At the other end, Damian Martinez was relieved to see a Cox piledriver just miss the target as the early exchanges were relatively even.
Forest keeper Karl Darlow then got lucky with a misplaced pass that landed at the feet of Atdhe Nuhiu in the penalty area but the Austrian failed to take advantage.
Nuhiu was a whisker away from getting something on a low Liam Palmer cross on the half-hour mark before Cox broke free down the left channel for the Midlanders only to hit wide from an acute angle.
The contest had an air of a single goal settling matters – and so it proved two minutes into the second period.
A sweeping move down the right saw Greg Halford deliver a deft ball into the heart of the six-yard box, leaving Cox the simple task of applying the finishing touch.
It was a blow for Wednesday given they had matched the play-off hopefuls all over the field to that point.
And it could have been worse as Forest had a penalty appeal waved away five minutes later when Cox went down under a Martinez challenge.
But Wednesday has plenty of purpose and Jose Semedo flashed a fizzing shot wide before Stuart Gray made a double substitution in a bid to get back into the game, introducing Reda Johnson and Jeremy Helan.
The move paid dividends in terms of possession as the Owls camped in the Forest half during the last 20 minutes and Jermaine Johnson also came on from the bench.
Yet for all their endeavours, Wednesday fell short in the final third and a sturdy visiting backline held firm to help the Tricky Trees to victory.
