One is because of the slow pace of the quest, and there is enough time for the linesman and the referee to let them see clearly.
There is another one, that is, because of the mud ground, the ball that is hit quickly will leave a mark on the clay court, which is a hitting point, if the player has doubts about the landing point of the ball, you can check it yourself first, and then let the referee check if there is a problem.
Also, Hawkeye is actually a lot of investment.
-
Reason 1: Whether to apply Hawkeye or not is decided by the organizers of the competition. Not all competitions have provisions for the installation of Hawkeye;
Reason 2: Clay courts have an inherently incomparable advantage on hard courts - ball prints. Referees and players can make clear judgments based on the traces of the point of contact between the ball and the pitch. Hard courts can't do that;
Reason 3: The adoption of Hawkeye is a controversial new rule. The French Open announced in 05 through the ITF that it would not use the Eagle Eye technology;
-
I think it's because the clay court leaves a clear mark, and players can ask the referee to come down and check if they have objections. This has been the case for many years.
Hard and grass do not have such conditions, and the ball speed is fast, it is not easy to judge, and it needs the help of the eagle eye.
Also, not everyone likes Hawkeye, like Federer. The French have always had a personality, and the organization and broadcast of the French Open are also different, so it makes sense even if you don't use Hawkeye.
When encountering a controversial ball, the referee comes down to look at the marks on the ground, although the marks on the clay court are more obvious, but there are many marks and it is easy to mix" This has not happened yet.
-
Because the ITF stipulates that on clay or sand courts, players can ask to check the ball mark if they think the referee has misjudged, and Hawkeye has an error of 3mm, in fact, the French Open also has Hawkeye equipment but does not provide information to the referee, only for the purpose of sorting out the player's technical statistics, such as the point of serve and the point of hitting.
-
Roland Garros's clay court is slower and the landing point is clear, so the French Open organizing committee has no plans to use Hawkeye, and Hawkeye costs millions of dollars, but it doesn't mean much for the French Open, so it doesn't need to.
-
As soon as you print it, you will stay, and you don't need it at all.
-
The new traces and the old ones can be clearly distinguished. Besides, the traces will not be there for a long time, and they will be cleaned up constantly. There weren't many balls that were suspicious.,It's easy to find if you have.。。。
-
The clay field can determine the landing point by looking at the traces left on the soil, and the eagle eye is very expensive, so there is no need for that.
-
The ball has a ball mark on the red clay, so it is not needed.
-
The clay field can determine the landing point by looking at the traces left on the soil, so there is no need.

No. Challenging Hawkeye means that when a player disagrees with the referee's decision (whether the ball is out of bounds), he can apply to play back the actual path of the ball simulated by the Hawkeye computer system to determine whether the penalty is correct.
When a player needs to challenge Hawkeye, he or she must declare "challenge" to the referee. However, the French Open does not have an eagle eye, so there is no eagle eye challenge.

The tennis ball loses a lot more energy than other courts in the process of bouncing on clay, so the ball speed will become very slow, which gives the player more time to run in place to hit the ball, Nadal runs very fast, and he can slide on clay, so even if the opponent is very tricky, he is likely to run in place. The super topspin ball, characterized by slow ball speed, high bounce, and high height over the net, and at the same time because of aerodynamic reasons, the ball falls very quickly, so this kind of ball is not easy to go down the net and not easy to go out of bounds, and it becomes difficult to hit the super topspin ball, because the bounce is high, so it must be hit over the shoulder, plus strong rotation, making the shot difficult to control, easy to make mistakes. Especially with a single counter-attack, the height of the shoulders is too difficult to maintain stability.
