Josh King completed his hat-trick in the 90th minute to give Bournemouth their first win in 2017 despite the Cherries missing two first-half penalties.
West Ham’s Andre Ayew looked to have earned a late point for the Hammers but Slaven Bilic’s men ultimately left the South Coast empty-handed.
Hat-trick hero King failed to hit the target after nine minutes after Sofiane Feghouli clumsily brought down Charlie Daniels. Only 48 seconds later, Michail Antonio gave West Ham the lead when he picked up a pass from Feghouli and squeezed in a shot from the edge of the box.
Former Manchester United player King leveled after 31 minutes when he flicked a loose ball in the box over the head of Jose Fonte with his right foot – and shot home with his left.
Five minutes later the Cherries were awarded a second penalty by Bobby Madley when Fonte was adjudged to have brought down Marc Pugh.
This time Benik Afobe stepped up but Darren Randolph dived low to his right to save his weak kick.
But King scored his seventh goal in seven league games after 48 minutes when he converted inside the box despite huge Hammers protests for handball against Afobe. Madley had to consult with assistant Stephen Child before allowing the goal.
West Ham duo Sam Byram and Ayew combined to give the former Swansea striker a tap-in after 83 minutes to make it 2-2 but King completed his treble in the last minute of regulation time to send Bournemouth six points clear of the drop zone.
Here are five things we learned:
1. After Old Trafford last week, this time Bournemouth got the home decisions
Tyrone Mings was in the stands at the start of his five-match suspension to see referee Bobby Madley award two penalties and allow the Cherries’ second goal despite strong Hammers protests for handball against Benik Afobe. Kevin Friend could have sent off Zlatan Ibrahimovic – and Mings – last week but only dismissed Andrew Surman. Andy Carroll was denied a late penalty when his cross hit the arm of Adam Smith.
2. Dimitri Payet was wrong about West Ham being boring
The former French favourite unleashed a barrage of criticism against his former club in his homeland yesterday, including the accusation that the Hammers are too defensive and dull to watch. That was certainly not the case at the Vitality Stadium. Defensively, Bilic’s teams were a shambles as they conceded two goals and two penalties – and Bournemouth looked like they could score at will. Ayew’s late equaliser looked to have got them out of jail after a poor performance but King’s late winner sent them back to east London with nothing.
3. There were no easy pickings for the Cherries from 12 yards out
Josh King scored from the spot at Old Trafford last weekend – his club’s seventh successful penalty in seven attempts. That record took a beating against West Ham as as first the Norwegian side-footed past the post – then Benik Afobe failed to fool Darren Randolph and the Hammers keeper easily grabbed his rolled spot kick.
On Football Focus, Jimmy Floyd Hasselbaink was not impressed with King passing the buck.
“You are a striker,” said the Dutchman. “Get that ball and get it in the back of the net. Yes, you are going to miss one or two but grab the ball.”
4. The Hammers need to buy better this summer
Sofiane Feghouli, previously better known for his rescinded red card against Manchester United, gave away the penalty, set up the Irons goal and generally ran around like a headless chicken. And the Algerian was the only signing from last summer on the pitch. Even Robert Snodgrass, a January purchase, started on the bench. The West Ham board need to add to a squad which is another Andy Carroll injury from missing any star quality.
5. First win in nine for Bournemouth
This crazy match had a final twist in the last minute of normal time when sub Jack Wilshere’s shot was saved by Randolph’s legs – and King drilled home the rebound.
