In the last days and shortly before the Australian Open, new allegations on fraud in professional tennis were reported. Anonymous whistleblowers published that some of the Top tennis players were involved in allegations on fraud. 16 to 50 top ranked players, even winners of Grand Slam titles, are suspected to have lost their matches on purpose while at the same time there where high bets on their loss. Although no names have been published apparently even 8 of this players are to play at this year Australian Open (one of the four largest tennis tournaments). Reports show that the players where targeted in their hotels before the games and offered USD 50,000 or more to participate in fixing their matches. Apparently tennis is a sport that is perfectly vulnerable for corruption since there are many thousands of matches a year and a huge gambling universe covering it. In my opinion it is really sad to see that the gambling industry is corrupting professional sports and that this did not happen just once or twice but several times and with a large number of players. The excitement of the sport is destroyed by corrupt players and greedy gamblers. This leaves the sports fan – who only wants to enjoy an exciting match – not knowing on what moves he can believe and in which players he can honestly trust.
