DJ Campbell probably wishes he could play against Posh every week.
The Blackpool frontman emerged from a difficult week to grab the only goal of the game to fire his side into the Championship play-off places.
Campbell was arrested at the club's training ground on Thursday in connection with a stabbing outside a London nightclub before being released on bail pending further inquiries and he was the Seasiders' hero when putting Posh to the sword for the second time this season.
Campbell grabbed two goals when helping previous loan club Derby to a 3-0 win at London Road in January and he was again on target for his latest employers.
Already-relegated Posh were never going to pose the toughest of challenges, especially with an entire team of senior players out through injury or illness.
Blackpool immediately seized the initiative with Campbell squandering an excellent opportunity inside two minutes, but he soon made amends when breaking the deadlock at the second attempt in the 11th minute.
Campbell saw a spectacular overhead kick well-saved by James McKeown, but was on hand to nod in the rebound for his 11th goal of the campaign.
Rookie keeper McKeown, in for the injured Joe Lewis, single-handedly kept League One-bound Posh in the contest with two fabulous saves to deny Ian Evatt and Campbell as the visitors threatened to run riot in the opening period.
He was again a formidable last line of defence after the break, pulling off another cracking stop to keep out Campbell before the Blackpool frontman was only inches away from converting a pass from strike-partner Brett Ormerod.
Campbell also received no joy from referee Colin Webster when appealing for a penalty ten minutes from time following a tangle with Andrew, while substitute Stephen Dobbie was also frustrated by McKeown as Blackpool chased a clincher.
One goal ultimately proved to be enough to send Ian Holloway's men into the top-six, although they had to survive a late scare as Mark Little fired wide on the half-volley with a rare chance for the hosts.
