A goal from Sonny Carey in the 55th minute opened the scoring for the Seasiders in South Yorkshire, as they took full advantage of a poor day at the office for their opponents.
Prior to finding the back of the net, the midfielder had already missed several chances to break the deadlock during the first half, but remained resilient to keep getting himself in the right areas.
Blackpool doubled their lead on the other side of the hour mark, with Ashley Fletcher beating Jackson Smith with a back post header.
Later in the second half, Carey added another goal of his own, finishing on the rebound after an initial shot from Niall Ennis was saved.
