Luis Suárez scored a 21-minute hat-trick as AFC Ajax made it two wins from as many matches at the beginning of the Eredivisie season with a 4-1 defeat of RKC Waalwijk. Suárez fired the hosts to victory with strikes on 71, 82 and 92 minutes after RKC's Benjamin De Ceulaer cancelled out Gregory van der Wiel's opener for the Ajax. Champions AZ Alkmaar gained their win of the season on Friday, defeating Sparta Rotterdam 2-0.
