Wolverhampton Wanderers striker Jay Bothroyd settled the black country derby, coming off the bench to score a late winner that sends Wolves into fourth place in The Championship, two points ahead of Albion and only a point behind Roy Keane's Sunderland.
The Baggies may have come into the match as favourites, and may have already put six past Wolves this season, but that counted for nothing when the two sides kicked off.
This was a much different side that ran out the tunnel to the one that had already capitulated twice to its bitter rivals.
There was desire, there was hunger and a willingness to back up the pre match words that the players wouldn't let the fans down again.
West Brom may have played the prettier football, and their fans may feel that they deserved at least a point, but goals make prizes and for all the chances Albion created they could not find a way past man of the match Matt Murray.
Neither side dominated the first half that was punctuated by some truly appalling decisions from Andy D'Urso, whose only real consistency was in being wrong.
Wolves had two decent shouts for penalties turned down, but it was D'Urso's decision to award a freekick to Albion for Michael Kightly being hacked by defensive bad boy Paul Robinson that drew the most derision from the Molineux stands.
In the second forty five Wolves pushed hard and dominated for long periods before Mick McCarthy introduced Jay Bothroyd whose impact was immediate.
Big games need big players, and Bothroyd is developing a reputation for coming up with the goods when his side needs it most.
Latching onto a long punt forward from defence, Bothroyd raced toward the Albion goal and fired in a low left footed shot that Dean Kiely turned around his far post.
Shortly after Bothroyd appeared to be brought down in the box, and once more Andy D'Urso waved Wolves appeals away,but there was nothing anyone could do to deny him next time he got a sight of goal.
Stephen Ward cut in from the left driving towards the West Brom penalty area, laid the ball off to Bothroyd with his back to goal and surrounded by defenders who turned, then jinked and fired a low left footed shot into the far corner of the Albion goal to earn Wolves their sixth win in a row.
Albion could have snatched a late equaliser, Diomansy Kamara wriggled through the Wolves penalty area but with nothing but Matt Murray between him and glory, Kamara found him unbeatable, as he had been all afternoon.
Pride has been restored and Wolves most unlikely promotion push goes on.
Six wins out of six, up to fourth place in the league, and revenge over West Bromwich Albion.
Mick McCarthy's magical Molineux reign continues, Wolves fans have smiles on their faces and the all important black county bragging rights.
Life rarely gets much better than this.
Inspired and unpassable, Matt blocked and saved everything Albion threw at him, showing why he's currently rated the best 'keeper in the division.
