Jason Koumas scored twice including a superb solo goal as West Brom maintained their lead at the top of the First Division with victory over Nottingham Forest at the City Ground.
An own goal by Forest defender Matthieu Louis-Jean seperated Koumas' two goals to confirm Albion's win - their fourth success in five away games.
Former Forest striker Marlon Harewood tormented Wigan on his home debut for new club West Ham, having a hand in Jason Jarrett's own goal and scoring his first goal for the Hammers from the penalty spot. The £500,000 signing then added his second after Wigan were reduced to nine men.
Kevin Horlock swept Alan Pardew's side into an early lead and after Jarrett's unfortunate own goal, Matt Jackson and Lee McCulloch were both shown the red card by referee Fraser Stretton.
Ipswich kept up their excellent recent run by winning at Cardiff, despite Robert Earnshaw's 16th league goal of the season for the home side. Earnshaw struck from the spot after Tommy Miller and Georges Santos had given Joe Royle's side a two-goal advantage.
Chris Bart-Williams restored Ipswich's two-goal lead when he added a third goal eight minutes from time and although Peter Thorne pulled another goal back Ipswich held on.
Darren Huckerby scored to keep Norwich in second place as they beat Crewe at Carrow Road, while a Michael Brown penalty, his first league goal since August, set Sheffield United on their way to three points against Preston at Bramall Lane, with Stuart McCall adding a second.
Ian Moore's equaliser earned Burnley a point at Sunderland's expense at the Stadium of Light after Kevin Kyle, back after injury, had given Mick McCarthy's side the lead.
A goal from on-loan defender Rob Edwards looked likely to keep up Crystal Palace's impressive run under caretaker manager Kit Symons against Coventry at Selhurst Park, but the Eagles had to settle for a point when Johnnie Jackson equalised for the Sky Blues in the last minute. Gary McAllister's men have now drawn six consecutive matches.
Struggling Derby saw off bottom-of-the-table Wimbledon thanks to two goals in two minutes from Marcus Tudgay and 16-year-old Lee Holmes. Nigel Reo-Coker had earlier cancelled out Nico Herzig's own goal to send the teams in level at half time.
Chris Swailes set Rotherham on their way to a precious win over Walsall at Millmoor, with Martin Butler sealing the points for the Millers with a goal against his former club.
First half goals from Paul Shaw and Chris Hope put Gillingham in command against Stoke at the Priestfield Stadium, and Andy Hessenthaler's side made sure of the points through Mamady Sidibe after John Eustace had pulled a goal back.
Bryan Robson's first game in charge of Bradford did not get off to the best of starts when visitors Millwall scored twice in four first half minutes through Tim Cahill and on-loan striker Nick Chadwick.
However, a tremendous second half turnaround saw the Bantams fight back to claim all three points thanks to goals from Danny Cadamarteri, Andy Gray and a late winner from substitute Michael Branch
