Bradford City claimed all three points at Bloomfield Road, as Kyel Reid’s clinical finish settled a game of few chances the away side's way.
Reid blasted home the only goal to leave the hosts without a win in four matches and now above the relegation zone on goal difference alone.
Mark Yeates had hit the bar in a first-half The Seasiders arguably shaded, but they never looked likely to strike after falling behind.
Their misery was compounded in injury time when Will Aimson was dismissed for a second bookable offence after an altercation with James Hanson.
Despite Bradford enjoying the early possession, it was their keeper called into action first. Against his former club, Yeates lined up a free-kick, but after it was blocked he had Ben Williams at full-stretch with his second effort.
Mark Cullen was next to threaten, volleying at Williams while on the turn, as he went in search of his first goal since December. David Norris followed suit on the half-hour mark, but Williams comfortably gathered his effort.
The stopper’s opposite number was looking back to his normal self after last week’s mistake and Colin Doyle held onto a curling strike from former Pool loanee Wes Thomas. The striker was looking hungry and put his next chance wide, under pressure from Tom Aldred.
The first sighting City’s leading scorer Hanson had of goal inevitably came with his head, but Doyle was equal to it on the stroke of half-time. At the other end, with the final chance of the half, Yeates was left disappointed, after his tantalising effort came back off the bar.
Half-Time: Blackpool 0 Bradford 0
After the break, the first chance of note fell to Thomas, who pounced on a sloppy clearance from Aimson, only to prod over the bar. He wasn’t the only former Pool man in Bradford’s ranks, and Tony McMahon tested Doyle from range soon after.
Their dominance was rewarded on 54 minutes however, when Stephen Darby skipped trough unchallenged and laid in Reid to drill home the opening goal beyond Doyle.
Neil McDonald then brought Uche Ikpeazu off the bench to provide a physical edge, with Cullen making way. However, that substitution had little impact, and Jack Redshaw and Martin Paterson followed soon after, with Jim McAlister and Yeates making way.
Paterson was instantly involved, having an effort put behind for a corner. However, there would be no further chances in a disappointing second-half and Pool’s misery was summed up when Aimson was shown a second yellow after clashing with Hanson in injury time.
