Ajax and Feyenoord suffered heavy away defeats against Sparta and NEC respectively.
Dutch giants Ajax and Feyenoord both suffered heavy away defeats against Sparta Rotterdam and NEC Nijmegen respectively.
Ajax were hoping to close the six-point gap on leaders PSV Eindhoven, but slumped to a shock 3-0 defeat in Rotterdam.
The visitors' cause was not helped by the dismissal of Wesley Sneijder after just 14 minutes for two yellow cards.
Sparta made the breakthrough on 35 minutes when Yuri Rose scored, with Sjaak Polak adding a second on 58 minutes.
With seven minutes to go, Sparta substitute Haris Medunjanin netted to give the home side a much-needed fillip.
NEC were equally emphatic in thrashing Feyenoord 4-1 as the visitors surrendered a five-game winning streak in the Eredivisie.
Brett Holman (pictured) opened the scoring on 54 minutes before on-loan Manchester United midfielder Chris Eagles netted on 80 minutes, just six minutes after coming on as a sub.
Dominique Kivuvu and Andrzej Niedzielan further demonstrated NEC's superiority before Feyenoord's consolation arrived in injury time courtesy of an own goal from Patrick Pothuizen.
AZ Alkmaar moved above Ajax into second in the table after coming from behind to record a 3-1 success at Heerenveen.
Afonso Alves put Heerenveen ahead on 20 minutes, but former Rangers striker Shota Arveladze levelled seven minutes later.
Danny Koevermans put AZ in front nine minutes from time and an 85th minute goal from Maarten Martens sealed the win.
ADO Den Haag notched just a second victory of the season after prevailing 5-2 at Groningen.
It was 2-2 at half time, with Den Haag having twice taken the lead through Goran Bunjevcevic and Richard Knopper, only to be pegged back by goals from Goran Lovre and Erik Nevland.
Kristoffer Weckstrom put Den Haag back in front three minutes after the interval and further goals from Knopper and Santi Kolk clinched the points.
Roda JC hung on for a 3-2 triumph at home to NAC Breda, who had taken a 40th minute lead from Edwin de Graaf.
Andres Oper, Dave de Fauw and Adil Ramzi then turned the game in Roda's favour, but Mike Zonneveld set up a tense finish with a goal for NAC on 86 minutes.
