London, June 18 (ANI): Between six and 12 players, who are due to compete in the men's singles at Wimbledon are on a "watch list" of individuals under scrutiny by the game's authorities because of past involvement in match-fixing.
The revelation comes from an investigation by The Independent into corruption in tennis, and into the methods that the authorities, including the world men's governing body, the ATP, are using to stamp it out.
The Independent understands the full "watch list" includes Russians, Argentines, Italians, Spaniards and players of other nationalities, including men from inside the top 50 as well as those at the lower reaches of the game.
The investigation has discovered that the ATP knows the identities of a group of big-time gamblers, in Russia in particular and also in Italy, who have wagered on "suspicious" games.
The top-level source said one challenge in fighting corruption is "sifting self-perpetuating gossip from hard evidence of corruption".
Another is stopping the use of "inside information" where "a privileged few profit for financial gain".
Then there is the challenge of catching "the small minority" whom the authorities believe are actively corrupt. (ANI)
