West Ham moved into the top four of the Premier League with a narrow victory over Tottenham that increases the pressure on Spurs manager Jose Mourinho.
Michail Antonio - back in the Hammers' starting line-up after a two-game absence - gave the hosts the perfect start, poking home after Hugo Lloris had failed to deal with Jarrod Bowen's cross.
Jesse Lingard's third goal in four league games was initially disallowed for offside against Pablo Fornals.
But VAR ruled that the Spaniard was not interfering with play when the Manchester United loanee skipped through the visiting defence before powerfully finding the far corner to make it 2-0.
Half-time substitute Gareth Bale, who registered a goal and an assist in Tottenham's Europa League win at Wolfsberger on Thursday, set up Lucas Moura to give Spurs hope, before hitting the top of the crossbar with a fierce strike 10 minutes later.
Son Heung-min also struck the woodwork in stoppage time.
The win - David Moyes' first over Jose Mourinho in 16 attempts - lifts West Ham two points clear of Chelsea in fifth, while Spurs remain in ninth.
"I am really enjoying my football," Lingard told BBC postmatch. "The lads have taken to me really well. Today we had to graft for the three points and we showed what we are capable of.
"I have been around a team winning trophies at Manchester United and I know about the winning mentality and what that can bring to the team. I have come here to play football. Football makes me happy and when we win."
