Blackpool survived a comeback on Saturday afternoon as Morecambe fought back from two goals down, but a late Dylan Sumner strike gave The Seasiders all three points.
Blackpool came into the match unbeaten after four games, and started the better side, highlighted by an early breakthrough.
Will Dunne got the opening goal, bundling the ball home at the near post from a Rowan Roache corner kick after just seven minutes.
The goal woke the visitors up, and they instantly put the pressure back on the leaders, with Fletcher shooting wide, before Harvey Simson tipped a Leif Davis free-kick onto the crossbar.
Sean Graham, on his debut for Blackpool, got down the left side halfway through the first period, but his cross just evaded Will Dunne at the back post.
As the half came to a close, Dylan Sumner, Rowan Roache and Emil Jaaskelainen were all denied by Morecambe ‘keeper Cameron Armstrong, with the score staying at 1-0 when the half time whistle blew.
The second-half started just like the first for Blackpool, as they scored early on. The captain, Ben Jacobson, doubled the hosts lead, as he headed home from a corner, providing Rowan Roache with his second assist of the afternoon.
Ten minutes later, and The Seasiders thought they had a three-goal lead when Will Avon slotted the ball home. However, it was ruled out for offside, and that decision changed the game.
Halfway through the second-half, Morecambe got a goal back to make it 2-1. Leif Davis whipped a free-kick in with his left foot and it was turned home by Kyle Hawley.
Will Avon was denied what could have been his second of the game, as Armstrong made a fantastic save from close range.
Morecambe then started applying pressure again, with Kai Herbert, a second-half substitute, heading just wide at the back post from a corner.
The equaliser came in the 79th minute, when the same combination worked for Morecambe. This time, Leif Davis delivered a corner, which Kyle Hawley duly tucked home from the six-yard line for his second of the game.
But just two minutes later Blackpool were back in front. Rowan Roache’s free-kick was parried away by the goalkeeper, but Dylan Sumner was there to finish the rebound and make it 3-2 to The Seasiders.
The final ten minutes was all Morecambe, but the Blackpool defence held strong to notch their second league victory of the season, and maintain their unbeaten run this term.
