LONDON — Russian tennis player Nikolay Davydenko was cleared by the ATP after a year-long betting investigation.

The ATP says it found no evidence of wrongdoing by Davydenko or Argentine player Martin Vassallo Arguello at their match in Poland in August 2007. The ATP says the case is now closed.

The probe centered on suspicious betting patterns during the match. Davydenko, then ranked No. 5, pulled out against his lowly ranked opponent in the third set citing a foot injury.

An online betting agency voided all wagers, citing an inordinate amount of money put on the match. Many bets came in for Arguello, even after he lost the first set.
