The French Open has been tarnished by allegations of match-fixing as authorities launch an investigation into suspicious betting activity involving a women’s doubles match.

Sports books reported a high amount of unusual betting activity in the first-round match involving Andreea Mitu and Patricia Maria Tig (Romania) against Madison Brengle (U.S.A.) and Yana Sizikova (Russia). French prosecutors have promised a full investigation into the allegations, believing that there’s merit in the case of ‘fraud in an organised group’ and ‘active and passive corruption.’

The individual players involved in the doubles match are not the focus of the inquiry as French prosecutors have probing gang activity over the suspicious betting patterns.

I was told by several sources that many bookmakers issued alerts for abnormal betting in Sizikova/Brengle match at Roland Garros, Set 2 Game 5, Sizikova on serve to get broken. She got broken to love. This is the video of the game (thanks to @UnArdeal for finding the video). pic.twitter.com/OPSO6hBjJj
