Three Wimbledon matches will be investigated for possible match-fixing, according to The Tennis Integrity Unit (TIU).
The anti-corruption body has been alerted to two Wimbledon qualifiers and a “main draw” match, during which potentially suspicious betting activity took place.
The investigation is part of the TIU’s quarterly reviews and it will also probe one French Open match.
“These will be assessed and reviewed in keeping with the TIU match alert policy,” the TIU said in a statement.
The TIU could investigate matches for a number of reasons. This can include “unusual betting patterns,” which could be triggered by playing conditions or injuries to certain players.
The TIU stress that an alert is “an indicator that something inappropriate may have happened” but, in itself, is not evidence that match-fixing did happen.
The first round of Wimbledon matches was marred by a succession of early retirements or withdrawals. The TIU’s probe into match-fixing is not believed to be related to these withdrawals, however.
The Telegraph reported that no British players are being investigated.
