AZ Alkmaar moved to within three points of leaders PSV Eindhoven courtesy of a 2-0 win over Willem II.
Danny Koevermans (15) and Maarten Martens (71) ensured a comfortable evening for the title hopefuls.
At the other end of the table, RKC Waalwijk claimed a much-needed 2-0 win over fellow strugglers Heracles to move off the foot.
The hosts were given a boost when Heracles were reduced in number by Jan Wuytens's dismissal after just 28 minutes.
It took just seven minutes for RKC to press home their advantage through Jan Vertonghen and Ricky van den Bergh completed the win five minutes from time.
Bas Sibum's 32nd minute goal gave Roda JC a 1-0 win over NEC Nijmegen, while Heerenveen and Vitesse Arnhem played out a goalless draw.
