ATP Tour

The ATP Tour is a worldwide top-tier tennis tour for men organized by the Association of Tennis Professionals. The second-tier tour is the ATP Challenger Tour and the third-tier is the ITF Men's World Tennis Tour. The equivalent women's organisation is the WTA Tour.

ATP Tour tournamentsEdit

The ATP Tour comprises ATP Masters 1000, ATP 500, and ATP 250 and the ATP Cup.^[1] The ATP also oversees the ATP Challenger Tour,^[2] a level below the ATP Tour, and the ATP Champions Tour for seniors. The Grand Slam tournaments, the Olympic tennis tournament, the Davis Cup, and the entry-level ITF World Tennis Tour do not fall under the purview of the ATP, but are overseen by the International Tennis Federation (ITF) instead and the International Olympic Committee (IOC) for the Olympics. In these events, however, ATP ranking points are awarded, with the exception of the Olympics. Players and doubles teams with the most ranking points (collected during the calendar year) play in the season-ending ATP Finals, which, from 2000–2008, was run jointly with the ITF. The details of the professional tennis tour are:
