Three defensive mistakes gifted Ipswich Town a comfortable 3-0 victory and left Wigan Athletic on the brink of relegation to League One.
Defender Craig Morgan was too easily dispossessed by Myles Kenlock who set up David McGoldrick to open the scoring on 22 minutes.
The Tractor Boys soon added a second when Jake Buxton gave the ball away in similar fashion and McGoldrick played through Freddie Sears to finish.
Ryan Colclough and Alex Gilbey forced keeper Bartosz Bialkowski into a couple of excellent saves as Latics tried to initiate a comeback, but then Gilbey dwelled too long on the ball and Sears broke clear to make the final score 3-0.
Latics remain seven points from safety with only six games remaining and the situation looks bleak.
Graham Barrow made three changes to the team beaten 2-1 at Newcastle with Ryan Colclough, David Perkins and Craig Morgan coming in for Sam Morsy, Callum Connolly and the injured Omar Bogle.
In an uneventful opening 20 minutes neither side threatened but on 22 minutes a defensive blunder by Morgan gifted the Tractor Boys the lead.
Kenlock dispossessed the overly casual Morgan and crossed the ball for McGoldrick, who finished clinically from close range.
Ipswich doubled their lead on 30 minutes following another blunder this time by Jake Buxton, who was dispossessed in his own half by McGoldrick and then fed Sears who ran clear to finish past Matt Gilks.
Latics tried to respond and had a couple of long range strikes from Max Power and Jamie Hanson just before the interval, both well saved by Bialkowski.
Alex Gilbey replaced Perkins at half time as Barrow tried to get Latics back in the game. Morgan saw a close range header saved on 50 minutes and Hanson fizzed a free-kick across the face of goal.
Colclough then saw his effort on 60 minutes superbly saved by the excellent Bialkowski.
Both keepers were on top form and Gilks saved from Grant Ward and Emyr Huws before he pulled off a double save to deny McGoldrick and the follow up from Ward.
Bialkowski then produced two top drawer saves to deny Gilbey from long-range and a point-blank effort from Jacobs.
But just when it looked like Latics might pull a goal back Ipswich broke, McGoldrick easily dispossessing Gilbey, and squaring the ball to Sears, who finished past Gilks at the second attempt.
Bialkowski made a another fine save to deny Gilbey from distance just before the final whistle but the three points had been secured for Ipswich long before then.
