Another Wimbledon has come to an end, and while there was a surprise winner in the ladies draw, there was almost a bland predictability about the gentlemen's winner. 

Spaniard Garbine Muguruza was magnificent as she overcame five-time champion Venus Williams, while the darling of centre court Roger Federer eased to a record breaking eighth title without dropping a set throughout the entire Championships.

Unfortunately, now that the gasps and cheers are no longer echoing through Centre Court, those remarkable efforts of the incredible athletes have been cast into shadow somewhat by reports that as many as three matches that were played at SW19 this year are set to be reviewed amid fears of match fixing.

A statement released by the Tennis Integrity Unit on Wednesday revealed that three matches had triggered match fixing alerts during the Championships. 

Only one of the three matches set to be reviewed occurred during the main draw, with the other two coming during the qualifying tournament.

TIU, who will review all three matches themselves, also confirmed that one match at the French Open is also up for review.

These alerts are triggered by unusual betting patterns across matches - but are not strictly evidence of match fixing.

The TIU also revealed that, during the second quarter of the year, they had received alerts for 53 matches, 40 of which were played at lower levels.

Three alerts were received from the ATP Tour, one from the WTA Tour, and five women's ITF circuit.

Such reports are understandably worrying for the sport, and many will be hoping that the investigations find no evidence of match fixing as such news would only mar what had been a splendid two weeks of tennis on those famous grass courts.

Up next for the stars of tennis is the US Open, which starts at the back end of August, and all associations linked with the sport will be hoping that there are no match fixing issues before then.
