Structure of the world rank


At the Beginning

Today, I will write about professional tournament ranking system. Do you know World Ranking in tennis? In 2012, number-1 ranked tennis player is Novak Djokovic. Then how is it decided? Organizations managing the ranking in men and women are different. It is a group called the ATP(Association of Tennis Professionals) to manage the world ranking of the man. On the other hand, it is a group called WTA(Women’s Tennis Association ) to manage the world ranking of the woman. But the structure of both is the almost same. Now I explain the structure in case of the man.

Ranking system

 The ranking of the man is managed by ATP as I explained it some time ago. Two ranking systems have been used by the ATP to date. They are Entry ranking and Champion’s race.

First, I will write about Entry ranking. Entry ranking is method to decide Annual ranking in total point of the high rank 19 games that I participated in during the past 52 weeks. Entry of the points will be detailed later. Because this method becomes the average of results of the past one year, even if there is the bad meeting of results, it does not affect ranking at all. So it is unpopular among some players.

 On the other hand, Champion’s race system which began in 2000 is all players start from 0 point. And it is a method that a point is added to every participation meet and decides annual ranking. For example, the player who put a good grade in a meeting to be held at the beginning of the year, he naturally become high-ranking of the champion race in the first half of the age. This system is plain and clear. However, there is too criticism to be short because only the occasional force is reflected by ranking.

Both methods have good points and bad points, too. Entry ranking is used by the singles again as general organization from 2006. In addition, as for the young player younger than 16 years, they limited the number of the meetings that they can participate in the year.

Introduction about points

Well, from now on, I want to explain structure of the entry of the point. The professional tennis players can obtain the point by winning in a meeting of the tennis, but the quantity of the point which to be provided changed by the kind of the meeting to participate in. Look at two below figures. The first figure showed the rank of the meeting. There are many points to get by meeting of the one on the figure. The second figure showed whether several points were provided in each meeting. For example, I can get 180 points if I win to best 4 in a meeting of the ATP500 series. The world ranking makes ends meet by adding up such a calculation for 52 weeks.

 

Next article, I will write about the kind and characteristic of tennis court. See you again!
