Mark Noble's 11th-minute penalty was enough for a laboured West Ham United win over Peterborough.
West Ham were awarded the spot-kick when Lee Frecklington was adjudged to have pushed Henri Lansbury after a low cross from Julien Faubert.
Carlton Cole curled wide as West Ham looked to add to their lead and then Lee Tomlin came close for the visitors.
David Bentley forced Peterborough keeper Paul Jones into a save, but West Ham rarely threatened.
At least Sam Allardyce's side can console themselves with the fact that they are now seven games unbeaten - but there will be concern that they dominated the opposition without managing to kill the game off.
George Boyd looked sharp for the visitors, but he was restricted to long-range efforts which rarely threatened Robert Green in the West Ham goal.
Peterborough's top scorer Tomlin was brought on at half-time and he almost equalised early in the second half but, as the West Ham defence backed off, his well-struck effort zipped past the post.
Bentley forced Jones into action when his effort stung the palms of the Peterborough keeper as the home fans grew continually more restless with their side's lack of creativity.
Despite the disapproving jeers from the home support, Peterborough could not fashion any late chances and West Ham held on for an unconvincing win.
