Davydenko fined for poor effort

Davydenko had been the top seed in St Petersburg

World number four Nikolay Davydenko has been fined $2,000 (£976) for not trying hard enough during his defeat by Marin Cilic at the St Petersburg Open.
The ATP said he had been guilty of "lack of best effort".

The umpire warned Davydenko about his conduct in the final set of his 1-6 7-5 6-1 defeat. The Russian later claimed his "legs were dead".

Davydenko is being investigated by the ATP over a match in August that featured irregular betting patterns.

Online betting exchange Betfair voided bets on that match, in Poland, between Davydenko and the 87th-ranked Argentine Martin Vassallo Arguello.

It finished when the Russian withdrew with a foot injury having easily won the first set.

But on Thursday night, Davydenko protested his innocence over the match in St Petersburg, which Cilic won 1-6 7-5 6-1.

The Russian was warned by Belgian umpire Jean-Philippe Dercq in the final set for not trying hard enough.
