Willem II and NAC Breda both made massive steps in their bids to retain their Eredivisie status by claiming away victories in their respective relegation/promotion play-offs.
De Graafschap's bid for a top flight place now look less than promising after a disappointing night on home soil that saw them lose 1-0 to Willem II.
A goal from Hungarian striker Zsombor Kerekes proved enough for Willem II, as he struck in the 87th minute.
NAC Breda were also away day winners as they came back from their trip to FC Volendam with an impressive 2-1 victory.
Paul Quasten had handed Volendam a dream start when he scored in only the eighth minute but NAC responded strongly in the second period to take control.
They were level in the 57th minute when Patrick Zwaanswijk struck, leaving Anouar Diba to wrap up the win late on.
