AMSTERDAM, Sept 20 (Reuters) - AZ Alkmaar handed champions PSV Eindhoven their first defeat of the Dutch league season on Saturday with a 1-0 home win.
Alkmaar, without a point up until today, dominated but had to wait until eight minutes before time when Mounir El Hamdaoui set up Maarten Martens to settle the match.
Early leaders Groningen made a dreadful start at Heracles Almelo when Oluwafemi Ajilore was sent off in the second minute for a professional foul.
Striker Bas Drost put Heracles ahead early in the second half but Petter Andersson equalised from close range to salvage a point five minutes before time.
Groningen are top with seven points after three matches, one more then ADO Den Haag who travel Graafschap Doetinchem on Sunday. PSV, easily beaten 3-0 at home by Atletico Madrid in the Champions League on Tuesday, are third, also on six.
Arch rivals Feyenoord and Ajax, respectively eighth and ninth with three points, meet on Sunday in Rotterdam.
At the bottom Vitesse Arnhem and Sparta Rotterdam collected their first point of the season in a 1-1 draw. Ricky van Wolfswinkel opened the scoring for Vitesse in the 50th minute but Charles Dissels replied on 72.
