The Tennis Integrity Unit (TIU) has revealed that three Wimbledon matches and one French Open contest will be investigated after suspicions of match-fixing were raised.
Between April and June this year the TIU received alerts in relation to 53 matches played, 40 of which were at ATP Men’s Challenger or ITF Men’s Futures events.
One main draw match at the All England Club also attracted the attention of betting regulators and gambling organisations, while two qualifying matches for the grass-court major were flagged up.
The TIU was also alerted over a solitary main-draw match at Roland Garros. The organisation revealed that it received 83 alerts in the first half of this year, compared to 121 in the same period for 2016.
The organisation stressed that the alerts are not evidence of match-fixing.
