1)52-week world ranking system:

ranking mechanism: the ranking determined by accumulating the points obtained by male professional players in four major open tournaments, nine masters tournaments, masters cup tournaments and five other best-performing events in the past 52 weeks

detailed rules: in the past 52 weeks, 13 compulsory events (four grand slams+nine masters series) and other effective international series have the best performance. The Masters Cup Finals will be counted into the ranking points as an additional 19th stop. The compulsory matches that you did not participate in can be replenished by points from other events. (The 52-week ranking is a moving system. Every past week, players will add the points gained in the new week and subtract the points gained in the corresponding week a year ago. )

(2) Champion ranking system:

Ranking mechanism: the ranking determined by adding up the points obtained by male professional players in the four major open competitions, nine Masters, Masters Cup and five other best-performing events in that year

Detailed rules: only the points of that year are counted. At the beginning of each year, it is calculated from . It is also the best other event in the 13-station compulsory race +5 stations. The qualification for the Masters Cup finals was determined by the ranking of the 18 champions in that year. In the year-end ranking, the finals points of the players who participated in the finals can be counted as extra points for joining the ranking at the 19th stop.

calculation method of points: each player counts the points of 18 events in the past 52 weeks (19 events in the year-end Masters Cup). These 18 events are: four Grand Slams, nine Masters and five ordinary events with the best results. The points of other events that players participate in become alternatives. When more than 52 weeks of the five best ordinary events need to be deducted, the sixth best score will be added.

Note: According to the above principles, the four Grand Slams and the nine-stop Masters are mandatory items, and no entry will be counted as . The other five events are optional. Not all players have five events, and 6 to 18 events are possible, but they must be:

1. They are in a low ranking and are not qualified for the Grand Slam Competition or the Masters Competition

2. They are not enrolled due to injury (which must be recognized by ATP) (excluding those who quit due to injury after registration)

One of the above two conditions is met.

The year-end ranking of the world ranking and the champion ranking:

The world ranking is to calculate the past 52 weeks, and the champion ranking is to calculate this year, so that the time ranges calculated by the two rankings will overlap at the end of the year. However, the range of points calculated by the two rankings is different:

1. Grand Slam Race Points, Grand Slam Qualifying Points and Grand Slam Qualifying Points

2. Masters Race Points, Masters Qualifying Points and Masters Qualifying Points

3. Tour Race Points, Tour Qualifying Points and Tour Qualifying Points

4.

Event classification:

Grand Slam: The highest level, with a total prize of over 2 million dollars, and the champion can get 1 ranking points.

Masters (including the year-end Masters Cup/Finals): The top 1 tennis masters sponsored by ATP, second only to the Grand Slam. The total prize money of each event is about $3 million, and the champion can get 5 ranking points.

gold tour: a high-level tennis tournament sponsored by ATP. The level is second only to the Grand Slam and the Masters, and it is divided into two levels:

(1) the million level: the total prize amount exceeds 1 million dollars, and the champion can get 3 ranking points

(2) below the million level: the total prize amount is less than 1 million dollars, and the champion can get 25 ranking points.

international tour: an ordinary tennis tournament sponsored by ATP, which is lower than the Grand Slam, Masters and Gold Tournament. It is divided into four levels:

(1) million level: the total prize amount is about 1 million dollars, and the champion can get 25 ranking points

(2) 8, level: the total prize amount is about -1 million dollars, and the champion can get 225 ranking points

(3) 6, level: the total prize amount is about 6,-8, dollars. The champion can get 175 ranking points. If you open the world ranking page of WTA's official website, you will find that not only the ATP world ranking points have doubled, but also the WTA ranking points have undergone earth-shaking changes compared with before. At present, jankovic's ranking points have reached 9,2 points, and Serena Williams, who leads the second place, has reached nearly 1,5 points, thus "creating" the highest score record in WTA ranking history.

Since 29, the calculation method of WTA ranking system has changed a lot, the most notable point is that the ranking score of Grand Slam champions has increased from 1 to 2, which is on the same track as ATP, which means that WTA must double the ranking score of players like ATP.
