Feyenoord suffered a setback in their bid to breach the Eredivisie's top three after going down 3-2 at ADO Den Haag on Saturday.
Ronald Koeman's men would have moved to within a point of joint leaders Ajax and Vitesse with victory at the Kyocera Stadion, but they were instead two goals down at the break thanks to Tom Beugelsdijk (36) and Danny Bakker (45).
Jordy Clasie (68) and Graziano Pelle (74) did drag Feyenoord level but Roland Alberg hit Den Haag's winner 13 minutes from time.
PSV Eindhoven's poor season continues to show signs of revival and a solitary goal from Jetro Willems was enough to book a 1-0 home victory over AZ Alkmaar.
The left-back struck in the third minute and PSV held out to secure the third win in four games that lifts them into sixth place.
PEC Zwolle are up to ninth after coming from behind to beat NAC Breda 2-1 at the Rat Verlegh Stadion.
Joey Suk opened the scoring after 19 minutes but Guyon Fernandez (50) and Mustafa Saymak (75) turned the game on its head with goals after the break.
Elsewhere, relegation-threatened Roda JC eased the pressure with a 1-0
home win over FC Utrecht, Guus Hupperts scoring the only goal after 34 minutes.
