Wednesday nudged Bolton closer to the Championship trapdoor with a 2-0 victory on a freezing midweek night over the Pennines.
Goals either side of the interval from Steven Fletcher and Rolando Aarons did the damage as the Owls slowly but surely turned the screw on Phil Parkinson’s relegation threatened side.
Once Fletcher broke the deadlock moments before half time, there looked only one winner and Wednesday duly delivered.
Prior to that, though, the Trotters had the edge in terms of possession but the visitors were sound at the back, routinely soaking up everything Bolton offered in the final third.
But only rarely did they break forward themselves and the Trotters were equally solid when the Owls ventured beyond halfway.
Remi Matthews intervened twice in the first half, comfortably thwarting Fletcher on both occasions, but the goalkeeper was powerless to prevent the Scot giving Wednesday the lead on 43 minutes.
Atdhe Nuhiu and Barry Bannan combined with some aplomb for the latter to feed Fletcher, who calmly clipped over the advancing Matthews and in.
It was just the boost both the game and the Owls needed and they started the second half on the front foot, causing Bolton problems with a higher press.
And on the hour, it was 2-0. Adam Reach delivered a slide-rule ball to Aarons down the left of the penalty area and the Newcastle loanee finished emphatically to post his maiden Wednesday strike.
With little to lose, the hosts moved upfield with more vigour and Craig Noone was unlucky to see his goal-bound effort hacked off the line by substitute Sam Winnall.
Winnall then almost had the final word at the other end with a low drive from Aarons' pass but Matthews dived across his line to parry clear.
A 3-0 defeat would have been harsh on Bolton, who nonetheless face an uphill battle to retain their current status, while for Wednesday, the unbeaten start to the Steve Bruce era continues.
Wednesday: Westwood, Iorfa, Hector, Lees, Palmer, Reach, Bannan, Hutchinson, Aarons (Palmer 87), Fletcher (Matias 82), Nuhiu (Winnall 57)
