Wilfried Zaha and Conor Gallagher got their names on the scoresheet for a second week in a row to help Crystal Palace end Wolves' five-game unbeaten run.
After a goalless first half, Palace finally made the breakthrough on the hour-mark when Zaha was slipped through to slot the ball home. His effort was initally ruled out for offside before a VAR review overturned the call.
Wolves thought they were granted a way back into the match when Joel Ward brought down his man on the egde of the box, with referee Graham Scott pointing to the spot.
