Tomas Soucek scored on his 27th birthday as West Ham United boosted their top-four hopes with a 1-0 win over Wolverhampton Wanderers.
West Ham controlled the first half but were unable to get the better of goalkeeper Jose Sa.
The Portuguese made strong saves to deny Michail Antonio and Manuel Lanzini while Declan Rice also struck a post with a superb strike.
Wolves had a great chance to go ahead in first-half stoppage time but Hwang Hee-chan placed a shot wide from Trincao's cross.
West Ham's winner came on 59 minutes when Antonio's pass found Soucek who prodded the ball in from six yards out.
Jarrod Bowen was also denied by Sa before West Ham saw out a win which moves them back up to fifth on 45 points, two points behind Manchester United in fourth.
A third defeat in five matches drops Wolves down to eighth on 40 points.
