So that is effectively that. Blackpool, unless there is a minor miracle or World War III will be playing their football in League One next season. Another appalling afternoon on the Fylde Coast where the foul weather matched the atrocious weather on an unplayable surface,
In a first half of few incidents, Wigan took the lead in the 45th minute after profiting on chaotic Blackpool defending. McClean's scuffed shot was inexplicably allowed to get to the back post, where Perch found midfielder Kim who tapped home past a seated Lewis.
Blackpool tried to show creativity early in the second half but were let down by their execution. O'Hara cut a left-wing corner to the edge of the box, where Delfouneso sliced his volley hopelessly wide.
The hosts piled on the pressure and looked certain to equalise after 62 minutes when O'Hara's free-kick was knocked down by Grant Hall to Tom Aldred, but his shot from six yards was brilliantly blocked on the line by the sliding Emmerson Boyce.
However, Wigan doubled their lead after 67 minutes when Maguire's header from Pennant's cross was helped into the net by a desperate Darren O'Dea on the line.
And the game was well and truly sealed for Wigan after 79 minutes when McClean slotted past Lewis - triggering a mass exit from Bloomfield Road.
Those disgruntled home fans who did leave missed Madine tapping home Tony McMahon's cross on 85 minutes, but it was merely consolation for the Seasiders who now have not won in six games.
15 points now stand between Blackpool and safety - considering we've only managed 22 points from 32 games to even get close to those above us is an unlikely scenario.
