Patrick Bamford netted his 12th goal of the season as Leeds United beat Crystal Palace 2-0 to move into the top half of the table.
Jack Harrison got Leeds off to a dream start after three minutes when his shot from the edge of the penalty area went in via a deflection off Gary Cahill.
Bamford could have netted twice in an opening half controlled by Leeds, but he had a header palmed away by Vicente Guaita and then skied over from close range.
But the forward got the goal he had been threatening against his former club on 52 minutes.
Mateusz Klich slid the ball through to Raphinha, Guaita parried the winger's shot and Bamford was on hand to follow up for his 100th career goal.
Harrison nearly added a third with six minutes left, but his powerful effort hit the crossbar and flew over.
Leeds' third win in four matches moves them up to 10th on 32 points. Palace remain in 13th position with 29 points.
