Wigan Athletic head into the break with a 1-0 lead over Blackpool in the Championship's relegation six-pointer after Kim Bo-kyung broke the deadlock in first-half stoppage time.
Both sides made a subdued start and there were no clear-cut chances in the opening stages, but a vital interception from Grant Hall was all that prevented Kim from going clean through on goal in the 17th minute.
Sheyi Ojo carved out a half-chance for Wigan moments later and let fly from outside the box, but the youngster's effort failed to trouble Blackpool stopper Joe Lewis.
Just as a dour first half looked destined to end with the deadlock intact, Kim bundled the ball home following a goalmouth scramble in the Blackpool box, knocking Jermaine Pennant's cutback beyond Lewis to pile the pressure on the league's bottom club.
