Wednesday slumped to a heavy defeat at Stevenage on Tuesday and extended their converse home and away form this season.
Boasting a 100 per cent S6 return going into this game, the record out of base was almost the exact opposite.
And the form book stayed the same as first half goals from Craig Reid, John Mousinho, Michael Bostwick and Laurie Wilson completely unsurped the visitors.
Darius Charles added another in the second half while Wednesday did manage a consolation through Gary Madine.
But to round off a totally forgettable night, substitute Jermaine Johnson was sent off late in the contest.
The Owls were out to build on Saturday's win over MK Dons but those ambitions were lost inside a disastrous opening period that saw them concede four goals to the rampant hosts.
The warning signs were there as early as the first minute when Mousinho sent a dangerous cross into the mix and Richard O'Donnell made a superb save from Bostwick's close range header.
Stacy Long then unleashed a daisycutter from distance that was deflected narrowly wide before O'Donnell came to the rescue side again after Charles tried to lob the Owls' keeper.
A goal was coming, though, and duly arrived on three minutes. Long tried another shot from outside the box that this time was too hot to handle for O'Donnell and Reid was on hand to mop up the spillage.
Suitably buoyed, Stevenage pressed on and doubled their advantage on ten minutes. Mousinho picked up possession and motored across the Wednesday backline before drilling a powerful drive across O'Donnell.
Incredibly, the home side bagged a third eight minutes later. The ball fell kindly 20 yards from goal to Bostwick, who sent in an opportunist effort on the volley that sneaked into the net off the post.
The stunned Owls fans had to wait until the 20th minute to see their side threaten when Ben Marshall fired a vicious shot from the edge of the area that Chris Day did well to divert over the crossbar.
Play promptly reverted to the other end, though, and Jon Ashton was almost on the scoresheet but for a fine last-ditch tackle from Lewis Buxton.
On 38 minutes, Stevenage did add another - and in bizarre circumstances as the ball struck the shins of Wilson and went in after two deflections in the penalty area.
It was a remarkable first half, with Wednesday giving themselves the proverbial mountain to climb after the break.
Gary Megson made three immediate changes, with Red Johnson, Jermaine Johnson and James O'Connor all entering the fray - Rob Jones, Julian Bennett and David Prutton made way.
The Owls certainly saw more of the ball in the second half but Day remained untroubled in the Stevenage goal for the most part.
The Hertfordshire side seemed the more likely to score next and almost did so on the hour when skipper Mark Roberts missed a gilt-edged chance at the far post.
The inevitable fifth came on 68 minutes, when Charles showed neat feet and good skill in the box to turn his marker and place calmly into the bottom corner.
Madine slotted past Day six minutes later to give the travelling faithful at least something to cheer but all in all, it was a dismal display by Wednesday with a result to match.
Jermaine Johnson rattled the bar in the closing stages with an angled piledriver but by then it was just a matter of playing the game out to a conclusion all but decided midway through the first half.
To rub salt into the wound, JJ saw red on 86 minutes for an off the ball incident and Wednesday's woes were complete.
