Blackpool failed to build on a positive start against Brentford, and opened their campaign with two defeats from two on home soil.
The Seasiders made the perfect start when Nathan Delfouneso planted a header into the bottom corner.
However The Bees were worthy of their equaliser which came thanks to Alex Pritchard’s neatly taken goal.
And after the break Stuart Dallas turned the game on its head, firing into the roof of the net, as Blackpool heads dropped.
Substitute Sergei Zenjov had the best chance but was thwarted by David Button, as The Seasiders finished the beaten side for the fourth time this season.
Blackpool had started the contest well, and after Ishmael Miller’s effort was blocked, Donervon Daniels headed over from the corner that followed.
Next loanee John Lundstram tried his luck, but lashed his effort wide from the edge of the box.
And The Seasiders were rewarded for their positive start with the opening goal on 16 minutes. Delfouneso started and finished the move, playing in Francois Zoko down the left, before meeting the Frenchman’s cross with a thumping header into the bottom corner.
Blackpool’s tails were now up and Lundstram again shot from the range, this time forcing Button into a routine save.
The visitors had their moments, but a series of corners came to nothing due to some solid Pool defending.
But Blackpool’s rear-guard was finally broken on 37 minutes when Moses Odubajo set up Pritchard, and the Tottenham loanee prodded home from the edge of the box.
And Pritchard was at it again moments later, collecting Alan Judge’s short corner, before twisting past Tomasz Cywka and shooting at Joe Lewis.
That was it for clear-cut chances in the first half, but Miller had a goal-bound effort blocked by some brave Tony Craig defending, as the two sides went in level.
Half Time: Blackpool 1 Brentford 1
Six minutes after the break, and The Bees edged ahead with the first chance of the second half. Dallas outmuscled Daniels inside the Pool box, before rifling an effort into the top corner.
Blackpool now looked flat and Riga changed his side with the introduction of Edu Oriol, who made his debut in place of Cywka.
And the Spaniard had a positive impact, setting up David Perkins, who fired irrationally over the bar.
Next Perkins interchanged with Tony McMahon, who saw his left-footed effort held by Button, before Edu Oriol dragged his shot wide.
Blackpool were trying to force the contest, and after Lundstram flashed another effort wide Nile Ranger came on for his debut, taking the place of Miller.
Brentford continued to look threatening however and substitute Jota fired wide, before Edu Oriol shot at Button.
On 81 minutes Riga his final change, swapping Zoko for Zenjov.
And the substitute had a golden chance to equalise, latching on to Ranger’s flick but seeing his low effort kept out by Button.
Blackpool's last chance came from a corner, which Lewis came up for, but ultimately it came to nothing and Pool were beaten.
