New Wigan manager Roberto Martinez`s baptism of fire in his first few weeks in the job continued after his much-changed side were thrashed 4-1 by Blackpool in the second round of the Carling Cup.
Martinez shook things up following successive defeats by Wolves and Manchester United but his fringe players failed to deliver.
Ishmel Demontagnac made the breakthrough in the third minute when he thumped a shot beyond goalkeeper Mike Pollitt from the edge of the box.
Blackpool extended their lead in the 19th minute with Mike Pollitt looking at fault as he was slow to react as Ben Burgess drilled in a shot from the edge of the area that did not have much power and went into the corner.
Blackpool then made it 3-0 in the 33rd minute with Wigan all at sea at the back as Paul Scharner conceded a penalty after flooring Billy Clarke as he homed in on goal. Charlie Adam stepped up and although Pollitt got a hand to his effort, he was unable to prevent him scoring from the rebound.
The Tangerines made it 4-0 in the 66th minute with a marvellous strike from Gary Taylor-Fletcher who weaved his way into the area before finding the corner. Wigan grabbed a consolation goal in stoppage time when Antonio Amaya marked his debut by heading in Ben Watson's corner.
