Feyenoord and Twente continued their impressive starts to the season and lead the way in the fledgling standings. Steve McClaren's Twente moved onto ten points from four games with a 2-1 victory over Waalwijk.
Bryan Ruiz and Blaise Nkufo were on target in a one-sided first half before Charlison Benschop brightened up an otherwise dour second period with a consolation for Waalwijk, who have yet to pick up a point this term.
The triumph put the Enschede side top of the standings for a couple of hours before they were overtaken on goal difference by Feyenoord, who ran out 4-0 winners against Roda.
Sekou Cisse, Jon Dahl Tomasson and Jonathan de Guzman put the Rotterdammers in the driving seat with first-half goals and De Guzman sealed the victory with his second three minutes from time.
Champions AZ Alkmaar claimed their third consecutive win with a dominant display at Heerenveen to finish the weekend in third place. AZ did all the running in the first half, but had only a Martin Lejsal own goal to show for it.
The hosts improved after the break, but Mounir El Hamdaoui killed off the game with a neat finish after 64 minutes to make it 2-0.
Three goals in the last half hour at the Philips Stadion enabled PSV Eindhoven to come from behind to see off Breda 3-1 for their second win of the campaign.
Edwin de Graaf put Breda ahead after eight minutes and that was how it stayed until four minutes after the hour mark when Danny Koevermans levelled. Koevermans grabbed a second after 73 minutes and PSV wrapped up the points in stoppage time through Ibrahim Afellay.
Ajax slipped to sixth after being held to a goalless home draw by Sparta Rotterdam. Luis Suarez hit the post with a curling effort just after the hour for Martin Jol's side, but that was as close as they came to a breakthrough.
