Mark Noble's first-half goal proved enough for West Ham United to claim three points against Burnley at London Stadium.
The Hammers captain had gone close with a long-range effort before Ben Mee fouled Winston Reid in the penalty area in first-half stoppage time.
Tom Heaton saved Noble's penalty but the midfielder was able to slot in the rebound.
Manuel Lanzini went close to doubling West Ham's lead, and Darren Randolph beat away a Scott Arfield free-kick as West Ham endured some pressure.
Sean Dyche’s visitors pressed hard for an equaliser after half-time, with Sam Vokes missing several chances, but the Hammers held out for their fourth league win, climbing two places to 15th.
