PARIS (AFP) -- Russian tennis star Nikolay Davydenko has been fined 2,000 dollars for not trying hard enough during his shock defeat by Croatian qualifier Marin Cilic at the St. Petersburg Open.

Davydenko was recently implicated in a betting scandal and the ATP, which governs men's tennis, handed down the sanction Friday.
The ATP said in a statement: ""Nikolay Davydenko was fined 2,000 dollars for lack of best effort in his second-round match against Marin Cilic.""
Davydenko, the top seed in St. Petersburg, played formidable tennis in the first set against the 102nd-ranked Cilic but in the last two sets he made numerous errors and committed 10 double faults.
He was warned by Belgian umpire Jean-Philippe Dercq in the final set for not trying hard enough.
Davydenko said after the match: ""I double-faulted to lose a game in the third set and he gave me a warning saying I was trying to lose on purpose.
""I was simply shocked to hear him say that. This is just outrageous. How does he know what I was trying to do? I was so upset with the whole thing I started crying.""
Davydenko aroused suspicion following irregular betting patterns prior to his first-round match against Argentine Martin Vassallo Arguello in Poland in August.
The Russian, who is reportedly being investigated by the ATP, is scheduled to take part in next week's Paris Masters, where he is defending champion.
