Authorities say game's integrity intact

The governing bodies of tennis said they have full confidence in the integrity of the sport but admit there is a threat from potential match-fixing. The men's ATP Tour, the International Tennis Federation (ITF), the WTA Tour and the Grand Slam Committee met to discuss various recent claims of corruption on Friday.

"The ITF, WTA Tour, ATP and the Grand Slam Committee have full confidence in the integrity of our sport," a statement said.

"Today's meeting reaffirmed tennis's unified approach to protecting that integrity.

"While we do not believe that our sport has a corruption problem we do recognise that a threat to the integrity of tennis exists."

Tennis came under the spotlight in August when a match between Russia's Nikolay Davydenko and lowly-ranked Argentine Martin Vassallo Arguello in Poland was voided by British online betting exchange Betfair because of unusual betting patterns.

The Russian has strenuously denied any wrongdoing.

Last week, Andy Murray said players believe that matches on the ATP Tour were being fixed.
