PSV Eindhoven leapfrogged Ajax at the head of the Eredivisie with a 3-0 win over NAC Breda on Saturday evening.
Ronald Koeman's charges made a slow start to the campaign, but they have hit form in recent weeks and were far too good for NAC.
Jefferson Farfan was the star of the show as he netted twice on the evening, with PSV's other goal coming from Philip Cocu.
ADO Den Haag and Excelsior shared the spoils in an entertaining affair at Zuiderpark.
ADO twice came from behind, as goals from Michael Mols and Tininho cancelled out strikes from Andwele Slory.
A last minute goal from Luis Suarez lifted Groningen to a 2-1 win over Roda JC.
Roda led just before the hour as Dave de Fauw netted for the visitors, but Groningen rallied and Erik Nevland levelled before Suarez's late intervention.
