Wigan dent Toon hopes with emphatic win
Fourth-placed Newcastle came crashing down to earth against Roberto Martinez's relegation battlers who continued their fight for safety following recent wins over Liverpool, Manchester United and Arsenal.
Wigan came flying out of the blocks with Victor Moses scoring twice in the opening 15 minutes and they were 4-0 up by halftime with Shaun Maloney and Franco Di Santo adding the others.
"We have reached a good level in the last stages of the season, with a clinical finish in the last third," Martinez told Sky.
"I am sure many people will say Newcastle had a bad day, but we played really well and we deserved it."
Newcastle boss Alan Pardew said: "If you don't have the intensity that matches the other side you are in trouble, and we didn't today and they got the early goals that changed the face of the game.
"They were superb and can take great credit from this victory - they were excellent."
The result at Wigan threw the race for Champions League places wide open.
Manchester United and Manchester City, who meet at the Etihad Stadium in what is virtually the title decider on Monday, will fill the first two places, while Arsenal look set to finish third even though they could only draw at Stoke where Robin Van Persie's 35th of the season cancelled out Peter Crouch's opener for the home side.
Arsenal have 66 points, four clear of Newcastle, but it is no longer definite that the fourth-placed finisher will qualify for the Champions League.
If Chelsea, who are sixth, beat Bayern Munich in the Champions League final next month and finish outside the top four, they will take the last qualifying spot as holders.
Aston Villa, embroiled in the relegation fight, drew 0-0 at Midlands rivals West Bromwich Albion and although they have only won once in 14 matches, they stayed 15th on 37 points, ahead of Wigan on goal difference.
Manager Alex McLeish, who was jeered by fans when Villa lost at home to Bolton on Tuesday, told the BBC: "I have had to show my experience and leadership and that has come to the fore. I will not curl up and die. I will persevere to the end as I always have done."
Sunderland ended their four-match run without a goal with a 2-2 draw against Bolton as Kevin Davies scored twice for the visitors to keep alive their hopes of avoiding the drop.
Davies put the strugglers ahead after 26 minutes before Nicklas Bendtner equalised for Sunderland who took the lead early in the second half with a James McClean free-kick.
Davies saved a point for Bolton who stayed in the drop zone but have a game in hand on their rivals.
Besides Wigan, three other teams scored four with Everton crushing Fulham 4-0 at Goodison Park where Nikica Jelavic scored twice, once from the penalty spot, taking his tally to 10 for the Toffees since moving from Rangers in January.
Everton, who also scored four at Manchester United last week, have now won 19 successive home league matches against Fulham and confirmed all three points with further goals from Marouane Fellaini and Tim Cahill.
Swansea City and Wolves produced a thrilling match at the Liberty Stadium where Andrea Orlandi headed Swansea ahead after only 24 seconds - the quickest goal in the Premier League this season and the fastest for five years.
Swansea raced into a 4-1 lead after 31 minutes with further goals from Joe Allen, Nathan Dyer and Danny Graham, before Wolves fought back to draw.
Stephen Fletcher scored their first after 28 minutes with Matt Jarvis getting two and David Edwards the other as Wolves salvaged a point, although they will still finish bottom after being relegated last week.
