Wigan moved out of the Barclays Premier League relegation zone and pushed Blackpool into it with a comfortable 3-1 victory at Bloomfield Road.
Hugo Rodallega put the visitors ahead in the third minute and Charles N'Zogbia made it 2-0 in first-half stoppage time.
Mohamed Diame netted a third midway through the second period, rendering DJ Campbell's late reply for the Seasiders a mere consolation.
Wigan looked more up for the battle from the off and within three minutes they had taken the lead. Blackpool defender Craig Cathcart slipped as N'Zogbia fed the ball through to Rodallega, who coolly slotted it through Matt Gilks' legs and into the net.
Gilks then punched away a ball into the box from Ben Watson but Wigan doubled their advantage as N'Zogbia collected the ball after Charlie Adam had been dispossessed by Diame, breaking into the box and finishing past Gilks.
After seeing Adam strike a free-kick into the Latics wall, Blackpool boss Ian Holloway needed no further prompting and he made a triple substitution after the break, bringing on Matt Phillips, James Beattie and Jason Puncheon.
N'Zogbia was on the attack again soon after, though, and produced a shot that stung Gilks' palms before Diame was next to try his luck.
He was off target on that occasion, but then Diame made no mistake when he received the ball from Rodallega, turned and hit a shot that deceived Gilks by deflecting off Neal Eardley on its way towards goal.
There was still life in the hosts and with seven minutes remaining Campbell made it 3-1, sliding in to convert Phillips' cross after a free-kick had come off the wall, but they could not find a second.
