Belgian Maarten Martens struck twice to help AZ Alkmaar past amateurs GVVV Veenendaal with a 2-1 win in their Dutch Cup quarter-final on Wednesday.
GVVV, who reached the last eight after surprise wins at top flight Excelsior Rotterdam and second division Sparta Rotterdam, stunned Alkmaar on 10 minutes when a cross from Dennis van Meegdenburg surprised goalkeeper Esteban.
Their lead lasted just 10 minutes when Martens equalised with a free-kick and the attacking midfielder sent Alkmaar into the semi-finals midway through the second half when he finished with a well-placed shot after combining with Adam Maher.
Heracles Almelo cruised through after a 3-0 win at home over RKC Waalwijk. Samuel Armenteros and Kwame Quansah scored before the break and Marko Vejinovic added a third before RKC's Evander Sno was sent off with 17 minutes remaining.
On Tuesday, Heerenveen came from behind to beat Vitesse Arnhem 2-1 to reach the last four.
Dutch league leaders PSV Eindhoven will host NEC Nijmegen on Thursday in the remaining quarter-final.comments
