Davydenko upset, draws warning from umpire for not trying

Top-seeded Nikolay Davydenko , interviewed in a suspicious match earlier this year, said he was warned for not playing hard enough by the chair umpire in his loss to Marian Cilic at the St. Petersburg Open on Thursday.

Davydenko won the first set in 27 minutes, but drew a rebuke from chair umpire Jean-Philippe Dercq in the third set before succumbing 1-6, 7-5, 6-1.

"When I made a double fault, he gave me a notice for a wrong behavior on the court as if I was throwing the match," Davydenko said. "I was surprised. I've never heard anything like this before. No matter how I'd played, no matter what had happen to me, I was never given such a notice."

The ATP is investigating, and has spoken to Davydenko about, an August match in Poland in which online gambling site Betfair voided bets involving the Russian because of irregular betting patterns. The Russian withdrew from that match against 87th-ranked Martin Vassallo Arguello in the third set because of a foot injury.

Davydenko said that during the exchange, Dercq asked him about his condition, but Davydenko first said there was nothing wrong and later said the problem was in his legs.

"He could not solve my problem anyway, that why I first told him I was OK, but I didn't play the way I did in the first set. That's why he gave me a notice," Davydenko said. "Later I told him that my legs have collapsed. I could not move," Cilic's victory was the second in seven weeks against Davydenko.
