Controversies
The ATP launched a match fixing investigation of Davydenko's match against Martín Vassallo Argüello in Sopot of 2 August 2007, after several large bets were placed at an online British gambling company, Betfair, in Argüello's favour after Davydenko had won the first set 6–2. Davydenko withdrew from the match during the third set with a foot injury. Although Davydenko had suffered three first-round defeats in his last three tournaments, was injured in an earlier-round match, and showed signs of injury in the second set, it did not make sense to Betfair that such a heavy betting volume would go in Argüello's direction at that point of time in the match. Per its agreement with the ATP, Betfair notified the Tour. It has since been revealed that nine people based in Russia had bet US$1.5M on Davydenko losing while two unknown people would gain US$6M from the loss. A total of $7M was wagered on the match, ten times the usual amount. Due to these irregularities, all bets were voided. On September 11, 2008, Davydenko, along with Arguello, were cleared of any involvement in match-fixing. The inquiry, which lasted over a year, was the longest ever held into match-fixing in tennis.
Further controversy also surrounded Davydenko after one of his matches at St. Petersburg Open in October 2007. During his 1–6, 7–5, 6–1 defeat by Marin Čilić, he was given a code violation by umpire Jean-Philippe Dercq for not giving his best effort. He was later fined $2000 (£987) by the ATP, but the fine was rescinded upon appeal. The following week, he lost 6–2, 6–2 to Marcos Baghdatis at the Paris Masters. This generated some controversy, as Davydenko was cautioned by the umpire to do his best during the match.
