Blackpool's status as a Championship club now looks in serious jeopardy, after fellow strugglers Wigan Athletic claimed three comfortable points at Bloomfield Road.
In a match built as a relegation six-pointer, The Latics were the better side throughout, and leave the hosts anchored to the foot of the table with hope running out.
Kim Bo Kyung opened the scoring by tapping home on the stroke of half time, before Harry Maguire and James McClean made things safe on a dismal day for Pool.
Gary Madine grabbed a consolation goal late on for the hosts, but they never looked like making a fight of it during the closing stages.
The opening 15 minutes of the contest had produced nothing to write home about, as a pair of Wigan corners came to nothing in front of the South Stand. It took 18 minutes for the first shot to arrive, but Joe Lewis was well placed to smother Sheyi Ojo's effort.
The dire contest went a further 15 minutes without incident, but unfortunately for Blackpool it was at the cost of one of their shining lights. Henry Cameron went down unopposed, and was forced off injured, with Nathan Delfouneso replacing him.
The Seasiders wasted their first chance of the half, as Jamie O'Hara's corner was headed wide by a tumbling Madine. And in the final minute of the 45 Grant Hall headed an even better chance off target from another O'Hara set piece.
The hosts punished Pool's inability to take them chances in first half stoppage time. McClean's shot deflected to the back post, and with the home defence sleeping Jermaine Pennant was on hand to set up Kim to tap home.
Half Time: Blackpool 0 Wigan 1
Moments into the second half a clever corner from O'Hara set up Delfouneso, but the striker sliced wide from the edge of the box. It didn't take long for Steven Davies to enter the contest, as he replaced David Ferguson.
He was instantly involved, earning a free-kick which O'Hara curled well over. All the action was coming from the midfielder's set pieces, and his next delivery eventually found Tom Aldred, who saw his volley cleared off the line by Emmerson Boyce.
From a rapid Latics counter attack Wigan could have claimed a second, but Marc-Antonie Fortune curled wide of Lewis' right-hand post. However they did make the game safe on 67 minutes, as Maguire's looping header crept in, despite Aldred's best efforts.
McClean then forced Lewis to save low to his left, before he headed into the stopper's hands soon after. However with his third chance the Irishman was deadly, spearheading a Wigan counter attack, before planting his effort past the exposed Lewis.
With five minutes left The Seasiders did at least get themselves on the scoresheet, as Madine tapped home Tony McMahon's cross at the back post, but no further action followed and Pool were beaten.
