The Association of Tennis Professionals (ATP) drafted a list of professional bookmaking players, which bet while watching the game from stands. The players used the 20-seconds necessary for bookmakers for changing the odds.
The list contains names of 15 players from different countries. It was passed to the Madrid Tournament (is to start on October 13) organizers. ATP recommended not to allow these players to the stands.
Also, ATP advised tournament managers not to allow spectators to use notebooks for real-time bookmaking.
To me, the decision is totally incorrect and unfair against these players. They are not breaking any law, they are simply enough smart to make money by bookmaking. It seems that ATP leaders have connections with bookmakers and are interested that people lose by betting, not win. Not nice at all.
