ATP Entry Ranking

The ATP defines the ATP Entry Ranking as "the objective merit-based method used for determining qualification for entry and seeding in all Tournaments for both singles and doubles, except as modified for World Team Championship, World Doubles Championship and Tennis Masters Cup...The Entry Ranking period is the immediate past 52 weeks, except for: the Tennis Masters Cup, which is dropped on the Monday following the last ATP event of the following year; Futures Series Tournaments, that are only entered into the System on the second Monday following the Tournament's week. Once entered, all Tournaments, except for the Tennis Masters Cup, remain in the System for 52 consecutive weeks."

The ATP explains that the reason behind continuing with a 52-week rolling system is "to determine seedings and tournament entry status [as] it is not practical to use the INDESIT ATP Race." It further notes that "The Race, while indicating the hottest players in the game at any stage, does not necessarily indicate an overall standing in the game. This is especially valid at the start of the year when early tournament winners may well be leading the Race but are not yet established top players for the purposes of seeding and tournament entry."

The ATP Ranking is based on calculating, for each player, his total points from the 13 main events - the four Grand Slams and the nine ATP Masters Series tournaments - and his best five results from all eligible International Series tournaments from the past 52 weeks. The Tennis Masters Cup counts as an additional 19th tournament for players who qualify for the circuit finale. For each major event a player is not accepted he may count one extra International Series event towards his ranking.
