The Seasiders suffered their third consecutive defeat, as the Posh claimed a 5-1 victory at the Weston Homes Stadium.
Goals from Malik Mothersille and Joel Randall gave Darren Ferguson’s side a 2-0 lead inside the opening 17 minutes, before Kyle Joseph pulled one back for the visitors.
Blackpool’s joy was short-lived, with Kwame Poku quickly re-extending the lead shortly after the resumption of play.
Heading into the latter stages, Randall claimed his second of the evening to round off the win for Peterborough.
