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!
