Wolves 1 (Fletcher 45+1)
West Bromwich Albion 5 (Odemwingie 34, 77, 88, Olsson 64, Andrews 85)
A 5-1 humiliation by West Bromwich Albion in the Black Country derby meant that it was a dark day for Wolves and their supporters.
Perhaps fortunate to be level at the break, Wanderers played some of their best football in the opening minutes of the new half before conceding a sloppy second. After going close to an equaliser twice, the home defence then conceded three times in the final quarter-of-an-hour.
The team that finished the game at Queens Park Rangers a week earlier was named to start against The Baggies as Mick McCarthy opted for Kevin Doyle to play in a roving role on the right of midfield.
Albion kicked-off attacking the North Bank end and but for Wayne Hennessey they would have been ahead after just a minute's play.
Kevin Foley slipped as he went cut out James Morrison's low cross and Jerome Thomas ran in at the far post to smash a shot that the keeper blocked at the expense of a corner.
The visitors enjoyed all the early pressure until Matt Jarvis broke away in the eighth minute to force a corner with a deflected shot. Jamie O'Hara took the flag-kick but Steven Reid headed clear from a crowded area.
West Bromwich were soon back on the attack and Paul Scharner was wide with a back heel after he met a cross from Marc-Antoine Fortune.
Peter Odemwingie ran onto a through pass from Reid and hit an angled shot that was blocked by Hennessey. The Nigerian then blasted the loose ball high over the bar.
Scharner and Gareth McAuley respectively cleared successive corners from Jarvis and O'Hara, before Hennessey made a fine save from Scharner's volley despite the ball taking a deflection off Roger Johnson.
From the corner conceded, taken by Morrison, Steven Fletcher blocked Liam Ridgewell's close range effort at the far post.
O'Hara then went into the book for a tackle on Scharner that left the Austrian in need of treatment.
After two O'Hara corners were cleared by the Albion defence, Odemwingie gave them the lead in the 34th minute. He cut in from the right and hit a shot that took a hefty deflection off Dave Edwards to wrong-foot Hennessey.
From the restart Jarvis took the ball to the by-line but his low cross was cut out and cleared.
In the one minute of added time at the end of the half, Wolves drew level. Foley's throw-in found Fletcher and he was in position to take possession again after a brief exchange between Doyle and Sylvan Ebanks-Blake to hit a shot on the turn for his tenth goal of the season.
Half-Time: Wolves 1 West Bromwich 1
Wolves looked much brighter at the start to the new half and they were inches away from going in front when Fletcher's goalbound volley was deflected narrowly wide by Jonas Olsson.
A miscued Odemwingie shot went out for a throw-in on the far side, and then a minute later the striker laid the ball off for Thomas who blazed his shot high over the bar.
Former Molineux midfielder Keith Andrews, an interval replacement for Scharner, headed over from a Morrison corner and then Wolves lost the services of Sebastien Bassong with a hamstring injury. He was replaced by Christophe Berra.
Albion regained the lead in the 64th minute following a Morrison corner. Olsson headed the ball on to McAuley whose looping header clipped the post. Johnson's lofted clearance dropped for Olsson to hit a volley that slipped from Hennessey's grasp and trickled over the line.
Ben Foster made a tremendous save to thwart Fletcher who looked odds on for a second goal of the afternoon as his header drifted towards the top corner. From O'Hara's corner, in attempting to clear Johnson's header, Youssouf Mulumbu headed against the underside of his own bar before Ridgewell cleared.
Albion broke up field and Foley cleared off the line from Odemwingie who had run unopposed into the home area.
It was 3-1 in the 77th minute as Morrison's corner was helped on in turn by Ridgewell and Olsson for Odemwingie to hook the ball over the line from close quarters.
Five minutes from time Andrews rubbed salt in the wounds with a fourth as he ran in on Morrison's cross - the ball taking a deflection off Johnson on its was past Hennessey.
Foster fumbled an effort from O'Hara but the ball bounced kindly for the keeper to go behind for a corner.
But then Odemwingie completed is hat-trick with little difficulty as he converted Morrison's cross to crown a miserable afternoon.
