Wigan climbed out of the Premier League relegation places with a potentially crucial 3-1 over Blackpool on Saturday, which sent the Seasiders into the drop zone.
Hugo Rodallega set Wigan on its way with a third-minute goal and Charles N'Zogbia doubled the advantage in first-half stoppage time, dribbling past two defenders before slotting into the far corner.
It was 3-0 in the 67th when Mohamed Diame's speculative shot took a huge deflection off Neal Eardley to beat Blackpool keeper Matt Gilks, and though DJ Campbell pulled one back in the 83rd, it wasn't enough to save Blackpool.
The Seasiders sank to second from bottom, with Wigan, which started the day bottom, moving up to 17th.
Blackpool routed Wigan 4-0 on the opening day of the season as the newly-promoted side made a bright start to life in the top tier, but Ian Holloway's side has now won one of its last 13 league games. Blackpool has conceded the most goals in the Premier League and has the worst home record.
Defensive mistakes made Wigan's life easier. Craig Cathcart slipped as N'Zogbia passed the ball to Rodallega, who scored his seventh league goal of the season.
Charlie Adam was dispossessed by Diame in the leadup to the second goal, although N'Zogbia still had plenty of work to do.
Holloway made a triple change in the second half as he sought to turn around his side's form, but Wigan remained in the ascendancy and the third goal - though fortunate - was deserved.
Wigan manager Roberto Martinez felt confident enough to take off N'Zogbia and Diame, and Blackpool did at least pull a goal back, but Campbell's ninth of the season was scant consolation for the struggling Seasiders.
