Peterborough have taken all three points for the first time in five games against Coventry City this afternoon.
Gary McSheffrey came closest for the Sky Blues on a couple of occasions in the first half, but couldn't beat keeper Joe Lewis.
Former Nottingham Forest striker Emile Sinclair finally broke the deadlock late in the game to put Peterborough in front, after Coventry keeper Joe Murphy was unable to hold onto Paul Taylor's strike.
The Midlands outfit, who are without a win in 11 games, remain at the bottom of the table following the defeat.
