Joshua King scored a hat-trick as Bournemouth boosted their Premier League survival hopes by beating West Ham to secure a first win in 2017.
King had missed an early penalty for the Cherries when he fired wide of the post, and 48 seconds later West Ham took the lead when Michail Antonio swept a low shot into the bottom corner.
Bournemouth were given another chance from the spot after Marc Pugh was fouled but again failed to convert it as Benik Afobe's effort was saved by Darren Randolph.
But the hosts did not let their heads drop and were level when King hooked the ball over his marker before volleying home.
