Genk are now top of the table in Belgium courtesy of a first-half strike by Paul Onuachu.
Onuachu fired his fourth goal of the season when he hit target in the 16th minute at OH Leuven.
Genk now have 31 points from 12 matches, a point ahead of Antwerp.
Onuachu is back scoring goals for fun in Belgium after injury in pre-season slowed down his start in the new campaign.
Last season, the 28-year-old striker netted 21 goals in the league.
