Jemal Johnson's second-half strike set up Wolves' victory over Luton.
Carl Cort threatened early on for Wolves, drawing a save from Marlon Beresford, then miscontrolling another chance, before he sent a header wide.
But on 47 minutes Cort's persistence was rewarded when he flicked on for Johnson, who beat Beresford with a low shot that went in off the post.
Luton new-boy Sam Parkin had a penalty claim turned down and late on Johnson fired a shot straight at Beresford.
Wolves manager Mick McCarthy on Jemal Johnson
"I'm not sure exactly what the figure was, but whatever we paid for Jemal he's been worth it in our last two league games.
"He scored the only goal against Burnley and he's won us the game against Luton with a terrific goal.
"I thought he'd make an impact but I never envisaged him coming in and winning two games with two goals."
Luton boss Mike Newell on the penalty claims
"I thought it was a penalty and so did all of our lads.
"But the referee didn't have a bad game and he would have to be brave to give that decision so late in the game.
"I asked him about it and he said there were so many bodies in the way, it
would've had to have been a guess."
