The ATP will run a revised ranking system when the Tour resumes next month.

The rankings, which are used for tournament entry and seeding, traditionally operate on a "best 18" results basis over 52 weeks.

ATP rankings, which have been frozen due to the sport's shutdown from the coronavirus crisis, will now cover a period of 22 months: March 2019–December 2020.

The rankings have been frozen since March 16th, just days after the ATP Tour was suspended due to the COVID-19 pandemic.



The ATP says the revised Rankings system aims to deliver the following key aims:

• Provide flexibility and fairness to players across all levels in parallel with the condensed number of points available as part of the revised provisional 2020 calendar.
• Provide stability for players who cannot or prefer not to compete in 2020 due to health & safety.
• Provide a system that can adapt to further changes in the calendar if necessary.
• Reward players who perform well following the resumption of the Tour in 2020.
• Retain the principle of defending tournament points week by week in 2021, maintaining player mobility in the Rankings.

The ATP has issued a revised provisional calendar that sets a pathway for the resumption of the Tour.

The new-look ATP Tour calendar intends to resume on Friday 14 August.

• A player’s ranking will be comprised of his "Best 18" results between March 2019 and December 2020.
• A player cannot count the same Tour-level tournament twice in his "Best 18" breakdown. For example, a player who played the Mutua Madrid Open in 2019 and plays Madrid again in 2020, will count the better of those two results.
• Tour-level tournament points added in 2020 that count in a player’s Ranking Breakdown will remain on a player’s ranking for 52 weeks, or until the event in question is played again in 2021, whichever comes first.
