AMSTERDAM (AP) — Eljero Elia celebrated the start of the Dutch Eredivisie season by scoring a hat trick Sunday as Feyenoord thrashed FC Groningen 5-0.

Two-time defending champion PSV Eindhoven and Ajax also opened with wins as the traditional big three of Dutch football made no mistakes on the season's opening weekend.

Ajax beat newly promoted Sparta Rotterdam 3-1, with Colombian striker Mateo Cassierra grabbing the third on his debut to give new coach Peter Bosz his first league victory at the club.

PSV had the toughest outing, going a goal down at FC Utrecht on Saturday night before second-half strikes by Davy Proepper and Gaston Pereiro made sure Phillip Cocu's team started its title defense on a winning note.
