Tennis Professional Players Association (ATP) is the organization responsible for the operation of the World Men's Professional Tennis Championship. There are two world ranking systems, namely champion ranking and registration ranking, which is the "world ranking list" that has been implemented before. In short, the ranking of the champion is that every professional player stands on the same starting line at zero on the first day of each season until the Masters Cup at the end of the season, and the highest score is the tennis player ranked first in the world this season. The following year, the ranking list was invalid, and everyone stood at the zero starting line again.
According to ATP regulations, the champion ranking list accumulates 18 points for each player every season, and those players who are eligible to participate in the four Grand Slams and the Nine Masters Series must count this 13 point. Even if you can't compete because of injury, you should keep zero points on your head. In addition, combined with their best performance in the five stops of the international series, the points of this 18 stop add up to their annual championship ranking. For the eight players who qualify for the Masters Cup, the score of this world-class event will be counted as 19 extra event in their year-end championship ranking.
ATP said that today's world tennis has become more and more power-oriented, and the situation that only a few people dominated tennis in the past is gone forever. In order to make every master actively participate in daily competitions and improve the competitive level of competitions, this new reform measure was introduced this year. They say that the old world ranking in the championship is easy to understand and simple.
With the strengthening of reform, ATP is weakening the world ranking. Then, what's the use of running in the world rankings for nearly 30 years? ATP renamed it "registration system" World ranking is the rolling accumulation of points in the first 52 weeks. In the past, only the best results of 14 stations were counted in singles, but now it is changed to the best results of 18 stations as the champion ranking. This ranking is now only used for the selection of registration qualifications and participation in seed ranking and lottery.
But the champion ranking doesn't have this function. It only determines which eight players can participate in the Masters Cup. Before the Masters, the top seven players before the championship will directly qualify for the Masters Cup. The eighth place in the Masters Cup belongs to the top player among the four Grand Slam winners, not in the top seven, but must be in the top twenty. If the four Grand Slam winners don't meet this condition, then the player ranked eighth in the championship will enter the Masters Cup.
ATP pointed out that the champion ranking list shows who is the hottest player at any stage, while the world ranking list shows the overall state of a player in the past 52 weeks.
calculate
When 1973 started the ranking of men's computers and 1974 started the ranking of women's computers, the goal of the points system was not to attract the public, but to create an objective and trendy class system to help organizers select contestants and establish seed players. There is no doubt that this ranking system has achieved its goal, and ATP and WTA Tour have become the standard of all competitions.
1990, after the ATP was transformed into the ATP Tour, the original men's ranking system was adjusted, instead of the average ranking method, it was ranked by accumulating "the points of the best 14 matches". In 2000, after the ATP Tour was renamed ATP, two sets of points ranking systems were introduced for parallel use: championship and competition ranking.
ATP mainly promotes the new champion ranking system, but since 2003, more and more people have re-valued the value of the 52-week ranking system. At that time, people were a little confused. Which ranking calculated by the integral system is worthy of our admiration?
What is a 52-week ranking?
Players decide their ranking by the scores they get in the competition. How long will it take for a player's performance to be included in the ranking system? 52 weeks, the accumulation of all points gained in the past 52 weeks will determine your ATP or WTA computer ranking position. In the past, ATP only calculated the points of the best 14 events. After 2000, the 52-week ranking system no longer requires this, but accumulates the points obtained by players in all competitions. For example, Roddick started his career in the American West Coast Online Championship on February 28th, 2000, so he couldn't accumulate points for the first 52 weeks until February 28th, 2006 at 5438+0.
The 52-week ranking is a mobile system. Every week in the past, players will add the points gained in the new week and subtract the points gained in the corresponding week a year ago. ATP and WTA will constantly refresh their rankings within an average of 45 weeks. For example, in 2002, when Costa beat Ferrero to win the French Open men's singles championship, she scored 1 0,000 according to the standard of 52-week ranking. In 2003, after he entered the semi-final of the French Open and was eliminated by Ferrero, according to the standard of 52-week ranking, he could only get 450 points, but at the same time he had to subtract it from the 1000 points he got last year. With such a good result in the French Open, he got 550 negative points.
In the past, male and female professional players can not only get round points, but also get quality points from defeated opponents. The higher the ranking of the defeated players, the more reward points they get. Compared with the old ranking system, the 52-week ranking system currently used by ATP has the biggest change that the content of extra points is cancelled, and the calculation period is 52 weeks.
Controversial old ranking system
Since 1970s, the complex integral calculation system has been criticized and questioned by people.
"No one knows how to calculate the points at all," Sampras, a former ball king who has always been famous for his words and deeds, complained the most about the puzzling points ranking system in the past. "I just hope it can be like a normal competition. Whoever scores the highest at the end of the season is of course the world's number one."
Boucher, president of Miami Masters and former ATP president, commented on the points ranking system: "This is something that even people in the industry will be confused, and it is even more difficult for ordinary tennis fans to understand. In 2000, ATP introduced a new ranking system of champion points, and the biggest progress was to simplify an evaluation standard that most people can easily understand. "
"It's not easy to understand the complicated ranking system. Once you can do this, you will have a strong sense of accomplishment." An American crazy fan said, "But every year when I explain my experience to the fans at the Cincinnati Masters, I find that two hours later, they are still confused."
Of course, fans want to know why the world number one changed candidates, but in the past, explanations usually took a long time to speak or consumed too much broadcast time. After deducting points, adding points, replacing the worst grades with better grades, etc., ranking points have become a paradise for digital admirers and a nightmare for journalists. According to the 52-week ranking, the top ten ATP men's singles players will have a total score of more than 3000 points at the end of the year. Roddick, the number one scholar in 2003, broke the 5000 mark in a record-breaking way, but the average difference between positive and negative points of the players every week was less than 50 points. At this time, the ranking list is like being frozen, and there will be no big changes after half a year. However, the seemingly frozen old ranking system has dealt a heavy blow to the world tennis world at 1999. Kafirnikov was eliminated in the first round of the four-stop tour on May 3 of that year and became the world's number one a month later. However, due to his worse record in the same period 1998, the total score changed little after the addition and subtraction, while his competitor Sampras won the championship in the same period 1998, but he did not participate in the corresponding month's 1999. As a result, he was cut off by 230 points alive and gave the world's first place to the Russians.
People's unprecedented criticism of the old ranking system makes ATP have to be revised when the 2 1 century is coming.
What is the ranking of champions?
The championship points system, which has been implemented for three years, is to add up the points obtained by male professional players in four open competitions, nine masters competitions, masters cup competitions and five other best-performing events to determine the players' world rankings.
If a player is not qualified to enter the above-mentioned Grand Slam and Masters, wouldn't it be only five points a year and never have a bright future? The solution of champion ranking is that the points these players get in all competitions within one year are their total points, which are not limited by competitions. But as long as they get the chance to participate in the competition, such as getting a wild card, they must calculate the result of the competition, whether it is ideal or not.
The champion ranking retains the function of "reserving" the ranking for the players. When a player is forced to rest for a certain period of time due to injury, he can apply to ATP or WTA for "ranking protection". As long as it is within the reasonable healing period stipulated by ATP or WTA, the player's ranking will be regarded as the ranking before application, and all the small competitions in the past should be protected by default, and players should not be deprived of the correct selection and seed qualification. For example, Johansson of Sweden won the Australian Open in 2002 and didn't play a game because of injury in 2003. Because of the "ranking protection" of ATP, Johnson after his comeback will be regarded as the 23rd player in the world in the eight events in 2004 and enter the competition directly.
So, how do players get points? At present, professional tennis matches (except the year-end finals) all adopt the single elimination system. Players will get corresponding round points every time they advance to the next round, and the number of these points is determined by the ranking rules formulated by ATP and WTA. Moreover, the bigger the scale of the tournament, the higher the prize money, the more players and the more points given in each round.
