Matthew Pennington scored the only goal of the game as the Seasiders gave their play-off hopes a massive boost, with Wigan Athletic up next for Neil Critchley’s side on Saturday afternoon.
Elsewhere, both Oxford United and Stevenage were on the end of defeats in their midweek games, but Steve Evans’ side still remain one point clear in sixth and have a game in hand on Blackpool.
Meanwhile, Lincoln City are also a team to watch, with the Imps firmly putting themselves in the play-off picture after recent strong run of form.
