An investigation is underway about the possibility of fixed outcomes in some large tennis matches.

FOX's Jared Max reports:

Not that there's evidence of fire yet, but where there's smoke, there may be fire, which is why the Tennis Integrity Unit is investigating the possibility that three matches this year at Wimbledon as well as another at the French Open in June may have been fixed.

The Anti-Corruption Body of Tennis has responded to a series of alerts of suspicious betting patterns for two qualifying matches at Wimbledon and one match during the actual tournament, along with another from the French Open.

Tennis Integrity Unit said in the news release that "an alert on its own is not evidence of batch fixing, that unusual betting patterns could result from incorrect odds setting, informal betting, player fitness, fatigue and form, playing conditions and personal circumstances."
