West Ham moved up to fourth in the Premier League as they inflicted a sixth consecutive defeat on bottom club Norwich at London Stadium.
Jarrod Bowen set the Hammers on their way, nodding in Vladimir Coufal's inviting cross seven minutes after his earlier effort was ruled out by VAR, with Nikola Vlasic deemed to be offside and interfering with Norwich goalkeeper Tim Krul.
David Moyes' side were far from at their best but they still created enough openings to put the game beyond the visitors well before Bowen registered his second by turning in Arthur Masuaku's cross in the 83rd minute.
