Every player eligible to play in a Tennis Masters Series event is automatically entered into the draw. Entry is determined by a player's position on the ATP Entry System exactly 42 days before the tournament starts. Additionally, players will enter the main draw through the qualifying competition. Others will gain direct entry through wild cards awarded at the tournament's discretion. The number of qualifying positions and wild cards depend on the draw size of the tournament (see below). If eligible to play in one of Tennis Masters Series events, a player must count the points from these tournaments, even if it is a zero because he missed the event. (The same is true for Grand Slam events.) Just as in Formula One and numerous other sports, if a competitor misses a race or an event, he loses his chance to earn points.
