Wolves proved there was no FA Cup hangover following their recent exploits at Liverpool as they won 3-1 at 10-man Barnsley.
David Edwards scored twice and Kortney Hause was also on target, with Marc Roberts grabbing a consolation for the Reds.
Paul Lambert's outfit shocked the Premier League giants at Anfield on Saturday and a much-changed side turned on the style at Oakwell, inflicting Barnsley's first home league defeat since November.
Alex Mowatt, a recent arrival from Leeds, endured a nightmare debut for the hosts as he was sent off for a two-footed lunge on Jack Price five minutes before the break. His boss Paul Heckingbottom was also sent to the stands in a feisty encounter.
The visitors made the perfect start, taking the lead inside five minutes. Connor Ronan's free-kick was headed behind for a corner and from his set-piece, Edwards flicked a header goalwards and there was Hause on the line to smash the ball into the net.
Wolves nearly made it 2-0 from another Ronan corner, with Edwards' effort being deflected over the bar. Then it was Barnsley's turn to go close, with Marley Watkins heading Mowatt's corner kick just over. The big striker then fed Mowatt as he burst into the box, but his first-time shot was charged down by goalkeeper Harry Burgoyne.
Wolves almost doubled their advantage when good work from Bright Enobakhare set up Ronan, whose 20-yard drive clipped the edge of Adam Davies' left-hand upright.
It had been a tight first half, with referee Christopher Kavanagh blowing up for numerous free-kicks. From another Ronan set-piece, following a cynical foul by Angus MacDonald on Jon Dadi Bodvarsson, Wolves made it 2-0 as Edwards' shot was deflected past the despairing dive of Davies.
It went from bad to worse for Barnsley as Mowatt was dismissed for a crude foul on Price late in the first half, before confusion reigned on the stroke of half-time.
Referee Kavanagh awarded Wolves a penalty following a foul on Enobakhare in the box, but he changed his mind after a discussion with one of his assistants and awarded Barnsley a free-kick.
Barnsley carved out a rare opportunity after an hour, with Ryan Williams heading Adam Hammill's cross just wide, before Heckingbottom was sent to the stands after an ugly scuffle with the Wolves dugout.
The home boss had to be restrained by his coaching staff after words were exchanged between the two benches.
Wolves scored their third on the counter-attack. Enobakhare raced forward and threaded a through ball for Bodvarsson. His shot was palmed out by Davies to Edwards, who hammered the ball into the net.
Barnsley responded immediately. Hammill was brought down on the edge of the Wolves box and when his free-kick was parried by Burgoyne, Roberts was on hand to slam the ball in, but that was as good as it got for the hosts.
Barnsley boss Paul Heckingbottom:
"It wasn't our night and I am disappointed that we conceded the first two goals like that - and it gave us a mountain to climb. And then the sending off, so then the game was all but over by then.
"The naivety has cost us. I can accept conceding a goal from a set-play, but Edwards made the same run for the first three and got every header. That's why we lost. It showed me that we weren't right tonight and we can't keep conceding goals like that."
Wolves boss Paul Lambert:
"I thought it was fantastic after coming off the highs of an emotional game on Saturday, possibly the highest emotionally that I can remember.
"The feelings of the players, supporters and staff and everyone was associated with Wolves has been draining after all that had happened at Liverpool, so I decided to change it around."
