Match ends, Burnley 2, West Ham United 0.
Burnley manager Sean Dyche says a couple of "big decisions" in his team selection contributed to a vital win over West Ham at Turf Moor.
Goalkeeper Tom Heaton excelled after being recalled at the expense of Joe Hart and 19-year-old Dwight McNeil, also included as one of five changes to the side thumped 5-1 by Everton on Boxing Day, scored the Clarets' second goal.
"Joe has been magnificent for us and credit to him because he was the first to jump up at the end when Tom makes a big save," said Dyche, who had seen his side lose their previous three league matches.
"I decided the time was right for Dwight, who is a clever player who has some quality and ability. His family should take some pride in what he's doing. He'll get stronger and fitter and we hope he'll continue growing with the team."
Chris Wood put Burnley in charge with a right-footed finish from the left of the penalty area to conclude a sweeping move involving Heaton, Ashley Westwood, McNeil and Ashley Barnes.
And with the hosts repeatedly carving through the visitors, they pressed home their advantage before the interval, when 19-year-old McNeil turned in Westwood's cross at the far post.
It was a disappointing end to a strong December for West Ham, who arrived in Lancashire on the back of five wins from six games.
Despite the return of Marko Arnautovic, playing for the first time since injuring his hamstring at Cardiff on 4 December, Manuel Pellegrini's side were sluggish throughout with their best chance, a header from substitute Andy Carroll, drawing a fine save from Heaton late on.
The only crumb of comfort for the Hammers was that both Wood and Barnes spurned several excellent opportunities after the break to make Burnley's win more emphatic.
The win lifts Burnley above Fulham into 18th and level on points with 17th-placed Southampton, who lost to Manchester City.
Dyche returns to tried and tested formula
A run of six defeats from their last seven games has raised question marks over Dyche's position for the first time in his six-year tenure.
While the club finished seventh in the Premier League last season, that success was largely built on a solid defensive base. In contrast, the defence has been porous this term - leaking 41 goals so far, two more than the entire 2017-18 campaign.
And with failed attempts to combat that problem including the deployment of five defenders in their last three matches - all ending in defeats - Dyche reverted to type with a 4-4-2 formation.
Wood and Barnes offered physicality in a two-man attack and club captain Heaton's return to the line-up proved inspired.
Over 15 months had elapsed since Heaton dislocated his shoulder at Crystal Palace - the last time he featured in a league game for Burnley - but the 32-year-old exerted his influence on those in front of him, barking out instructions and providing organisation and leadership.
That contributed to West Ham managing just four shots on target and Heaton's understanding with his team-mates was evident as he raced out of his goal in the 15th minute to instigate the move that ended with Wood's goal.
Heaton positioned himself to calmly head the ball to Westwood under pressure from West Ham attackers, and he underscored a good day's work by superbly tipping Carroll's header on to the woodwork late on.
Hammers toil as Anderson fails to shine
A position just outside the top six felt like an implausible proposition for West Ham after they lost their opening four games but Pellegrini's side had the opportunity to move up to seventh at kick-off.
Instead this turned into a second blip in an otherwise fruitful December, their other defeat this month, against Watford, also a 2-0 reverse.
"It was frustrating because we wanted to win this game and had the chance to be seventh but we lacked energy to win it," Pellegrini said.
"We had a flight that arrived at 2am in the morning after playing Southampton. I was happy until two o'clock today. This was a game we were able to win - Burnley was in a bad moment but they played with intensity. Burnley recovered better because they had 30 or 35 hours' more [rest]."
Brazilian midfielder Felipe Anderson has played a principal role in West Ham's upturn but he struggled to make an impact against well-drilled and determined opponents.
Anderson won just 31% of his duels and his passing accuracy was also below par at 64%. And with West Ham's most creative player on the periphery it allowed Burnley to assume control.
Anderson was far from the only visiting player to underwhelm, though. Lucas Perez and Robert Snodgrass were withdrawn at half-time after ineffective displays, which contributed to the visitors managing just one shot in the first period.
The introduction of Carroll did add power and presence but the Hammers were unable to provide the aerial service he thrives on until the closing minutes.
