Wrexham manager Denis Smith took a gamble and it paid off with three points from an exciting game.
He said: "I took a huge risk because we had two clean sheets in our last two games and I changed the centre backs and a defensive midfielder.
"I might have been left with egg on my face. Fortunately it came off. I just felt that with two games in three days this might have been a bit too much for Brian Carey.
"He is 35 and while he wants to play I felt it would be stretching it to ask him to go through the whole game today and that is why I put Steve Roberts in. Brian came on as a sub later and did very well." He added: "We were top quality and our finishing was superb. Both strikers scored two goals each and it makes my life a lot easier." From the Blackpool camp manager Steve McMahon said he was bitterly disappointed. "It was a calamity, one mistake after an other," he complained. "You can't excuse our poor defending. That was a one-off for us and I don't know why it happened." Blackpool might have scored early on for a good start but Steve Elliott headed wide from Danny Coid's corner.
Chris Llewellyn hit two goals for Wrexham in seven minutes. For the first he took a long pass from Craig Morgan, ran from near the half way line, past two tackles and hit a left foot shot into the far corner as Lee Jones came off his line. His second goal was a simple tap in after Carlos Edwards and Paul Barrett made the opening.
Scott Taylor cut in from the right to head home off Dennis Lawrence to pull a goal back for Blackpool but they were soon struggling again.
Hector Sam gave Wrexham their third goal pouncing on the rebound after Barrett's first effort from a narrow angle came back off the post.
Jones saved a 20 yard drive from Llewellyn before Sam was on target again. This time Darren Ferguson, returning from a three match suspension, made the opening for Sam to beat the offside trap, run on 30 yards and shoot past the hapless Jones.
Right on half time Coid saw a deflected shot bounce off the crossbar and from the following corner Mike Flynn headed home for the final goal of the game.
Both sides changed tactics for the second half, Wrexham concentrating on defence while Blackpool were seldom able to push up from midfield.
