Raul Jimenez's third goal of the season handed Wolves their third straight home win as they beat high-flyers West Ham United.
The Mexican scored the only goal of the game in the 58th minute, tucking away Daniel Podence's neat cutback from outside the penalty area.
Victory over the Hammers means Wolves are now sixth in the Premier League table, three points off the Champions League places.
Story of the match
Both sides made one change each to their fixtures prior to the previous international break. For Wolves, Podence started a league match for only the second time this season with Francisco Trincao dropping to the bench.
David Moyes' change was a forced one and it came in the shape of Craig Dawson replacing Angelo Ogbonna, with the Italian defender set to miss the rest of the season after damaging his anterior cruciate ligament.
The Hammers, who were in search of their fifth straight league win, started the better of the two teams and were presented opportunities early in the game through Jarrod Bowen and Tomas Soucek.
A cross from the left was directed just wide by Bowen before Soucek's curling attempt from outside the area failed to cause Jose Sa any problems moments later.
The hosts did manage to grow into the game and showcased their quality as the first half went on. Ruben Neves' shot from distance was too easy for Lukasz Fabianski before Jimenez was presented with a golden chance.
Neves' delicious pass over the West Ham defence handed Jimenez with only the goalkeeper to beat but the striker's chipped strike trickled wide.
Wolves came out in the second half in the exact same way they ended the first, on top. Podence's audacious strike looked like it was going to hit the back of the bet, but Fabianski reacted superbly to tip the ball out for a corner.
Shortly before the hour mark, Lage's men made their dominance pay through Jimenez's third goal of the season. Some brilliant forward play by Nelson Semedo and Jimenez saw the Wanderers cut through the Hammers defence with ease.
Podence's smart cut back to the Mexican was perfect and he swept the ball into the bottom corner.
Moyes' side should have levelled in the final 25 minutes through Bowen. A nice piece of play between the winger and Michail Antonio created space for the 24-year-old, but he effort had too much on it.
Andriy Yarmolenko and Nikola Vlasic joined Manuel Lanzini off the bench as West Ham looked to keep their unbeaten run in tact, but all struggled to make an impact.
Max Kilman should have doubled Wolves' lead in the closing minutes when he was picked out by Rayan Ait-Nouri from a free-kick. The defender's touch was poor and his slashed the ball well over.
Next up for Wolves is the long trip to Norwich City next Saturday, whilst West Ham travel to Austria to face Rapid Wien in the Europa League before travelling to Manchester City next Sunday.
