The investigations come after irregular betting patterns involving one singles match and one doubles match in this year’s tournament in London. It is believed that several betting firms have reported the matches due to a series of abnormal bets, the exact details of which have yet to be made clear.

The first match involving possible manipulations is a first-round men’s doubles encounter, with numerous betting firms noticing high live bets that the favoured duo would be defeated. The pair won the opening set, thus increasing the odds on their defeat, before losing the remaining sets. The timing of the bets and the sums placed indicate irregularities.

The second match under investigation is a first-round singles match involving a German player, where a five-digit sum was placed at the end of the second set on the exact result. There were also special bets on the number of service games in the match, with both bets winning. It is, however, the opponent of the German player that has triggered suspicion.

The International Tennis Integrity Agency (ITIA), the body in charge of evaluating potential match-fixing in the sport, cannot comment on individual cases due to operational reasons, with the cases not made public until a full investigation has taken place.
