Four For Friday - Gambling

In the third round of Wimbledon, there was a match that was three sets. The two participants won and lost games and sometimes even points based on instructions from a person in the stands who did not sit in the players box. Each of the participants has been accused in the past of throwing matches when facing a much lower ranked player. The person in the stands sat at one of the baselines. They would use a quick almost baseball like sign to the player that could see. That player would then relay the signal to the other player. Because the players switched sides of the court, they each took turns communicating. Apparently the person in the stands had a team of people making in game wagers and made a fortune.
