Champions Ajax or PSV Eindhoven could yet close that gap, when they meet in the capital later on Sunday, but for now AZ are out of reach.
Three goals in 19 second-half minutes gave Feyenoord a 3-0 win at bottom side De Graafschap that keeps them on the fringes of the title race.
They will not have been buoyed to see leaders AZ Alkmaar scrape a 1-0 win over RKC Waalwijk but, thanks to goals from John Guidetti, Ruben Schaken and Sekou Cisse are five points behind the top-ranked side heading into the business end of the season.
The picture is far less prosperous for the Superboeren. With 27 games now played they have just 16 points to their name, 14 short of the current safety mark.
Heracles Almelo capped a memorable week with a 3-1 home win over 10-man FC Utrecht to further ease their relegation worries.
After president Jan Smit hailed the midweek 4-2 KNVB Beker semi-final win at AZ Alkmaar as the "high point in the history of the club'' the Heracles players ensured there was no league hangover today.
Samuel Armenteros fired them ahead after just three minutes and while Cedric van der Gun levelled on 54 minutes the game turned on Alje Schut's dismissal soon after.
Ninos Gouriye ensured they made full use of the advantage as he struck a double in the final 10 minutes to move Heracles eight points clear of the relegation play-off zone.
