A predatory strike from Nahki Wells 10 minutes from time gave Huddersfield all three points from a desperately poor Sky Bet Championship clash at Wigan.
The Terriers avenged Wigan's 2-1 triumph at the John Smith's Stadium back in November, by converting the only real effort on goal from both sides to win 1-0.
Elias Kachunga tried his luck from distance, with none of the Wigan players seeming to want to close him down. Home goalkeeper Jussi Jaaskelainen could only parry the ball to the edge of his six-yard box, and Wells was the first to react to slide the ball from close range.
Rai Simons watched from the bench as his Chesterfield remain deep in relegation trouble after they were held to a goalless draw by MK Dons in a lacklustre game at the Proact Stadium.
Both sides lacked quality and invention although the visitors came close to winning it in the final minutes with substitute Daniel Powell forcing Ryan Fulton into an outstanding save.
Omar Bogle scored twice and provided an assist as Grimsby ended Reggie Lambe and his Carlisle United teammates unbeaten home record in Sky Bet League Two with a 3-1 win at Brunton Park.
Carlisle led at the interval through a Charlie Wyke goal, his 16th of the campaign, but Bogle's double made it 18 league goals for the season and the striker also helped lay on a debut strike for substitute Adi Yussuf.
