Blackpool were beaten at home to Coventry City, who scored a scrappy winner in a game of few clear-cut chances.
Marc Antoine-Fortune converted from close-range midway through the first-half and that proved to be enough for all three points.
The Seasiders struggled to create opportunities on another frustrating afternoon and remain in the bottom four as a result.
Blackpool had started the brighter side and debutant Liam Smith tested Reice Charles-Cook with an effort from range. City’s first sight of goal came through Chris Stokes, but the defender’s header flew off target.
The hosts were forcing Coventry to shoot from range and former Pool man Jacob Murphy flashed a shot wide on 24 minutes. However, when the opener arrived it was for City. Colin Doyle appeared to be fouled when coming for the ball and Antoine-Fortune turned to blast into the roof of the net.
Blackpool attempted to respond instantly and Tom Aldred’s volley skimmed the side netting on its way wide. Jack Redshaw was next to be frustrated as his scuffed effort rolled wide of the mark.
Pool’s endeavour couldn’t be questioned but David Norris will have been disappointed not to get more on his shot, which dropped into the arms of Charles-Cook. Blackpool’s predicament almost escalated when Emmerson Boyce surrendered possession and Murphy set up Adam Armstrong, whose shot deflected wide.
Brad Potts then blasted over with half-time approaching, as Pool went in for the break behind.
Half-Time: Blackpool 0 Coventry 1
After the break there was little in the way of chances which provoked Neil McDonald to change his hand, bringing on Bright Osayi-Samuel and Mark Cullen for Jack Redshaw or Smith, who’d looked tidy in possession on his debut.
Osayi-Samuel was instantly involved, skipping through and having his shot saved by Charles-Cook. Coventry’s own substitution Andy Rose then set up Murphy who headed over.
As for Pool, Aldred headed over Jim McAlister’s corner on 70 minutes. Stokes then put his own header wide, as Uche Ikpeazu replaced David Norris for the home side.
The striker’s first contribution saw him volley McAlister’s corner way off target, while an effort from Rose bounced into the arms of Doyle moments later.
City finished the game with ten men after Stokes was stretchered off and they’d used all three substitutes. It would have little impact however, as a goalmouth scramble couldn’t force a late equaliser and Potts blazed over to compound Pool’s misery.
