ATP Open Era & Live Rankings

RANKING RULES BETWEEN 2020 AND 2021

Quick to recover from a system which worked less than satisfactory in 2019, the ATP first brought back points for ITF level events in August 2019, then made a series of modifications to the lower ranked events. They also added CHAL 50 and ATP CUP, to create a more well structured system for the new decade.

SYSTEM SPAN: 52-WEEK ROLLING SYSTEM [Tournaments counted for each player drop out of their breakdown 52 weeks after they enter the system]
SYSTEM TYPE: CATEGORY BASED [Tournaments have different point weights according to the type of tournament a player has entered. The higher category, the more points scored]
POINTS: ADDITIVE [Players receive points according to the round they are eliminated in. These points are added and players are ordered according to their total points]
TOURNAMENTS: BEST 18 [Only the best 18 tournaments results can be counted.]
MINIMUM PRIZE MONEY: $50000

BASE RULES

The 2020 system allows players to count their best 18 results and form a point total. Players are ordered according to this total. In addition, players are allowed to count the ATP Tour Finals and the ATP Cup as extra results beyond 18.
All tournaments are counted immediately after they are finished (on the upcoming Monday). Exceptions to this rule are ITF World Tour tournaments which are counted one week later. Once into the system, tournaments remain counted for 52 weeks. ATP Tour Finals drop on the Monday after the final regular calendar tournament of the year.
The rankings are published every Monday of the year. Exception to this rule are the mid-Mondays of tournaments lasting for more than one week: Grand Slams, Indian Wells and Miami tournaments.
A commitment player is defined as a player who has finished in the Top 30 at the year end rankings of the previous season.
All players must count all 4 Grand Slams and 8 Mandatory Masters for which they are a direct acceptance on the original acceptance list as well as their other 6 best results from all other tournaments.
If the player is not part of the original main draw acceptance list of a mandatory event and decides to not participate before the draw is released, they may count an extra non-Mandatory event.
In weeks in which a player does not have the mandatory 12 events, he is allowed to count extra non-Mandatory events to a total of 18.
Once a player becomes part of the main draw of any of the 12 Mandatory events, either as a qualifier, lucky loser, direct acceptance, special exempt or wild card, that tournament counts for his rankings, so any late withdrawal will be a 0-point penalty.

COMMITMENT PLAYER RULES

Late withdrawals from ATP World Tour 500 events shall result in a 0-point penalty. Commitment players must play 4 ATP World Tour 500 tournaments across a calendar year, one of which must be played after the US Open. Failure to do so, will result in 0-point penalties for all missing tournaments.

NON-COMMITMENT PLAYER RULES

Late withdrawals from ATP World Tour 500 events shall result in a 0-point penalty.

TIES

When two or more players have the same number of points, ties shall be broken with the following rules:

Total points from all Grand Slams, ATP Tour Masters 1000 Mandatory tournaments and ATP Tour Finals main draws, and if still tied, then,
The fewest events played (all penalties count as a played tournament), and if still tied, then
The total number of points from the players' best tournament, then, if needed, the second best, and so on.

ATP 1000 MASTERS EXEMPTIONS

Rankings-wise, players are exempt from playing up to 3 ATP 1000 Masters if they fulfill any of the following:

Players have reached the age of 30 at January 1 of the current year.
Players have participated in 600 ATP level matches. (pre-2010 non-ATP level matches also count, but only ATP level matches count after 2010).
Players have fulfilled 12 years of service (first year of service is the first year in which a player has participated in 12 tournaments offering ranking points).

Each of the items from the above exempts a player from an ATP 1000 Masters event. Players are not allowed to skip a tournament which they had withdrawn from at the previous edition without playing any match.

COVID-19 TEMPORARY 22-MONTH SYSTEM

Due to COVID-19 pandemic, tour was suspended between March and August 2020. Upon resumption, the ATP used a temporary 22-month rankings system:

SYSTEM TEMPORARY RULES:

Mandatory tournaments will no longer force player points.
All 2019 points present in the system at March 16, 2020, will have a 52-week increase to the period kept in the system, but will drop when another iteration of the same Tour level event is played.
All 2020 point events will drop after 52 weeks or when the 2021 edition of the event is played, whichever comes first.
If a player has 2 iterations (2019/2020) of the same event, the maximum points of the two is counted to the rankings, until the event is played again in 2021.
Between August 2021 and August 2022, all 2019-2020 tournaments are phased out with a 52-week drop to all 2021 events.
In 2021, the system will adopt a Best 19 rule to count an extra tournament to all players' breakdowns.

POINTS

Players are given points according to the round they lose in and the tournament's category.
Players reaching the second or any round of a tournament by drawing a Bye shall receive first round points if they lose in the first round they play in.
Players who enter a tournament by means of a Wild Card shall receive 0 points in the first round they play in.
