The Tennis Integrity Unit, which monitors and investigates corruption in tennis, described four Grand Slam tournaments as suspicious in the current season.
Under suspicion were two meetings of the qualifying round Wimbledon and one main.
Also questionable was one qualifying match Roland Garros. The basis for testing was the abnormal bet on these games, reports The Mirror.
The punishment may amount to a fine of up to 250 thousand dollars plus the amount that a tennis player or other tennis representative has earned as a result of fraud.
In addition, an athlete may receive a disqualification.
Let's note, appeals in these cases are considered only by sports arbitration in Lausanne.
