Two goals from Marcus Tudgay helped relegation-threatened Sheffield Wednesday to a much-needed win.
Just before the interval Tudgay beat the home defence to Deon Burton's cross and converted to give Owls the lead.
Carl Cort levelled when he connected with Lee Naylor's ball to power past Scott Carson in the Wednesday goal.
Burton added the Owls' second when he fired home after stealing past Gabor Gyepes, before providing the pass for Tudgay to score his second.
Wolves manager Glenn Hoddle:
"We haven't blown the play-off place, certainly. We are still in a very strong position.
"The way we defended for those three goals was poor. You cannot win matches anywhere defending like that.
"We didn't see this coming and we have for to start getting maximum points at home."
Sheffield Wednesday manager Paul Sturrock:
"I've been a bit critical over the last few weeks about the players not playing for 90 minutes but today they've gone and done it.
"Wolves is a difficult place to come to but we've got the win.
"They have done what we discussed all week and planned for."
