EINDHOVEN, Netherlands, Oct 23 (Reuters) - Timmy Simons converted a disputed penalty in the 10th minute to hand PSV Eindhoven a 1-0 victory over Ajax Amsterdam in the Dutch first division on Sunday.
PSV moved top with 22 points from nine matches, one more than AZ Alkmaar who crushed 10-man Willem II Tilburg 5-1. Feyenoord dropped to third following a 2-1 defeat at RKC Waalwijk.
Waalwijk are fourth with 18 points and Ajax fifth, eight points behind the leaders.
Referee Pieter Vink awarded PSV's penalty when Jefferson Farfan went down under a challenge from Urby Emanuelson and Belgian international Simons converted from the spot.
'The story of this match is the referee's decision after 10 minutes,' Ajax coach Danny Blind told reporters.
'I can live with it when we are the worse side in a match but this time it proved decisive. We had some good spells and created chances but lacked the precision to convert them.'
Ajax, who started with a 4-4-2 formation with Ryan Babel as central striker and Mauro Rosales on the right wing, created their first chance midway through the opening half.
Emanuelson broke through on the left but his cross was knocked over by Babel.
Nine minutes into the second half PSV's Ibrahim Afellay cleared an effort from Nigel de Jong on the goalline.
But Arouna Kone also missed two excellent opportunities for PSV in the final 10 minutes.
PSV coach Guus Hiddink was happy at the end of a tough week that yielded wins over Ajax and Alkmaar, and a 0-0 draw at AC Milan in the Champions League.
'I'm satisfied but it still is a pity that we play a match like this days after both teams had Champions League obligations,' said Hiddink.
'Today it was obvious that both sides missed the physical and mental power and I have to agree with my colleague Danny (Blind), it was no penalty.'
Maarten Martens opened the scoring for RKC before Feyenoord winger Romeo Castelen levelled with 12 minutes left.
Central defender Virgilio Teixeira struck the winner for the home team from close range in injury time.
Tarik Sektioui gave Alkmaar the lead after four minutes but Kemy Agustien equalised for Willem II, who were reduced to 10 men when goalkeeper Oscar Moens was dismissed for a 39th-minute foul on Barry van Galen.
Dutch international Denny Landzaat restored the advantage for Alkmaar from the penalty spot two minutes later.
Second half goals by Kenneth Perez, Martijn Meerdink and Gretar Steinsson completed the rout for Alkmaar.
