Rankings Explained



MEN'S

Ranking lists are generally released each Monday with the exception of no updated rankings being issued whilst the four Grand Slams or the events in Miami and Indian Wells are still taking place.

ATP Rankings, singles only at first, were first issued on 23rd August 1973 and were extended to include doubles from 1st March 1976. Apart from determining who were the best players in the world they were issued so as to be used by the majority of major tournaments as a basis of deciding the acceptance of entries.

They were not weekly as they are now (except for non issues in the middle Slams or during the events in Miami and Indian Wells) until 1979 with there being the following number of issues in the early years (and not always on a Monday).

1973 - 7 issues
1974 - 11 issues
1975 - 13 issues
1976 - 23 issues
1977 - 34 issues
1978 - 40 issues
1979 - 43 issues

Year end rankings initially were the last issue of a year, or the first one of the following year, until 1991 when ATP deemed "the year end" to be after their Singles & Doubles Championships, in mid/late November, so that they could print their media guide for the Australian Open in mid January.

In 2000 (discontinued in 2009 for singles only*) an additional ranking was initiated by the ATP. This was called the ATP Champions Race. All players start the year with zero points and began a calendar year race with the player accumulating the most points becoming the world number 1. This additional ranking was introduced in order to make things more understandable for the public and to ensure that the top players participated in the most prestigious tournaments.

* It is still being used for doubles because players change partners during the season and because doubles teams can be at different ranking levels, it is impossible to use the ATP Rankings on their own to determine who should qualify for the Barclays ATP World Tour Finals. For that reason the ATP kept the Doubles Race.


WOMEN'S

Ranking lists are generally released each Monday with the exception of no updated rankings being issued whilst the four Grand Slams or the events in Miami and Indian Wells are still taking place.

The first official rankings appeared on 3rd November 1975 and were used to determine acceptance into tournaments.

Rankings became weekly from March 1990 (except during Grand Slams and the events in Indian Wells and Miami when new ranking releases were delayed until completion of these events).
