French international Julien Escude scored the home side's winner after just 11 minutes to take Ronald Koeman's side well clear of title rivals PSV Eindhoven in the table.
In the other Eredivisie match to be played on Sunday, NAC Breda came from a goal down to win 2-1 at Utrecht.
It was the home side who took a 1-0 half time lead when Hans van de Haar scored 11 minutes in at the Nieuw Galgewaard.
However, van de Haar's day was to be short-lived after he was sent off on 32 minutes for a second bookable offence to leave Utrecht with ten men for the rest of the match.
NAC would turn things around on 64 minutes when Henk Vos brought the visitors level before Nourdin Boukhari became Breda's hero with his winning goal seven minutes from time.
