Eberechi Eze's powerful finish earned Crystal Palace a first win in four matches as they edged past Wolverhampton Wanderers.
The winger controlled Jordan Ayew's pass on the edge of the area before flashing a fierce left-footed shot past Rui Patricio on the hour.
Palace enjoyed the better of the first half, with Nathaniel Clyne and Michy Batshuayi both firing over.
Vicente Guaita twice denied Willian Jose on his first Wolves start in the second half, while Wilfried Zaha crashed an effort against the bar for Palace.
But one goal proved enough for the Eagles, who rise to 13th on 26 points, a place and three points above Wolves, whose winless run extends to eight matches.
