AMSTERDAM, Feb 4 (Reuters) - Wesley Sneijder scored a hat-trick to inspire Ajax Amsterdam to a comfortable 4-1 win over arch-rivals Feyenoord in the Dutch league on Sunday.
After 23 matches, PSV Eindhoven are top with 56 points, despite their 3-2 home defeat against AZ Alkmaar on Saturday, five more then Ajax.
Alkmaar are third with 50, while Feyenoord remain fifth with 42 points.
Sneijder opened the scoring for Ajax after 19 minutes with a deflected free kick and doubled the lead 12 minutes later when he netted from close range from a pass by Ryan Babel.
Ten minutes before the interval Tom van Mul added a third and then Anelos Charisteas pulled one back for Feyenoord but four minutes before the final whistle Sneijder added his third.
Elsewhere, Vitesse Arnhem and NEC Nijmegen shared the points in a 1-1 derby draw. Roy Beerens opened the scoring for the visitors eight minutes into the second half but with 15 minutes remaining Mads Junker equalised.
