(CNN) -- AZ Alkmaar were crowned Dutch champions for the first time since 1981 after Ajax were thrashed 6-2 at PSV Eindhoven on Sunday.
AZ had wasted the chance to clinch the Eredivisie title in front of their home fans when they lost 2-1 to Vitesse Arnhem on Saturday, but it proved academic.
PSV, who are battling to finish fourth in a poor season by their own high standards, found their form against their old rivals.
Edison Mendez gave PSV the lead in the 22nd minute before Ibrahim Afellay doubled the lead just after the half hour mark.
Nordin Amrabat got the third in the 41st minute before Luis Suarez pulled one back for Ajax just before half-time.
Jason Culina, Balazs Dzsudzsak and Otman Bakkal added further goals for the rampant home side in the second half with Miralem Sulejmani scoring a consolation for Ajax.
Ajax's defeat leaves AZ with an unassailable 11-point lead over second-placed Twente Enschede with only three games to play. Ajax are a further point adrift in third and still chasing their first Dutch title after five barren seasons.
