Chapter 240 Can't even touch the ball

After a brief absence, Roches returned to normal thinking: "Just now I have been paying attention to Zhang Guan's serve action, so I didn't see clearly how the ball came, and I didn't even see where the ball landed. Is it out of bounds? The referee has awarded an ACE ball, indicating that it is in bounds, but will the referee see it wrong? Should I try to challenge Hawkeye? But if the referee does not make a mistake, I will waste it in vain An opportunity for a challenge."

The Hawkeye system, also known as the instant replay system, is a computer system used in tennis to track and record the path of the ball and display a graphic image of the recorded actual path, as well as predict the future path of the ball. The whole system uses eight to ten high-resolution high-speed cameras to capture the trajectory of tennis balls from all angles of the court, and then simulate and present them with 3D technology.

This system can help referees make decisions to determine whether the ball has gone out of bounds. And when the athlete believes that the referee made a mistake, he can also request a Hawkeye challenge. According to the rules, each athlete has a total of 3 opportunities to challenge Hawkeye in each set, and one more opportunity will be added when the game enters the 7th inning. If the athlete succeeds in the challenge, then the opportunity to challenge is still reserved. An opportunity to challenge will be lost.

This technology came out in 2001. In 2006, the U.S. Open became the first Grand Slam event to use Hawkeye to assist, and this year's Australian Open was the first to use the Hawkeye system. At the same time, not every stadium has the Hawkeye system. Only large stadiums will be equipped with the Hawkeye system, and small stadiums will not spend money to install the Hawkeye system.

Today, the Vodafone Stadium where Zhang Guan and Roches are located, as the second largest stadium in the Australian Open, is of course equipped with the Eagle Eye system.

Just when Roches was still hesitating whether to take the Hawkeye challenge, there was a sudden exclamation from the audience, and everyone's eyes turned to the display board showing the speed of the serve, Roches I also looked down and just saw the number "208".

"A serve at a speed of 208 kilometers per hour! It's so fast!" Roches was shocked, and immediately thought of another possibility: "The referee may not be able to see the serve so fast. Moreover, this is Zhang Guan's first tennis match. A serve, if the referee can't see clearly, it will probably be counted as inbounds to encourage players. In this case, I have a great chance of succeeding in challenging Hawkeye!"

Thinking of this, Roches immediately signaled to the referee to challenge the Hawkeye system.

A 3D simulation of the ball quickly appeared on the big screen on the field. The ball clearly fell within bounds, and it was still a full finger away from the sideline.

"Oops, I wasted a chance to challenge. Such an obvious in-bounds ball, if I had paid more attention just now, I would have been able to tell that it was in-bounds. By the way, how could Zhang Guan send the ball so fast? It must be a coincidence !” Roches looked frustrated, and then he was ready to catch the ball again.

Zhang Guan started his second serve, throwing the ball, swinging the racket, and hitting the ball in one go.

This time, Zhang Guan still used a flat serve, and Zhang Guan made adjustments in this serve, and the ball he chose landed closer to the sideline.

"Whoosh!" Roches had to concentrate a lot this time. He saw the ball flying towards him, and then he was about to make the movement of catching the ball, but suddenly realized that his action was too late, and the ball would inevitably be caught again. Not anymore.

This time, Roches didn't hesitate. Since he was doomed not to catch the ball, he had to carefully see if the ball went out of bounds.

"Out of bounds!" Roches shouted in his heart, but the ball fell into bounds.

"ACE, 30-0." The referee broke the score again. However, the ball speed of 207 kilometers also appeared on the display board next to it.

"Oh... oh... oh..." There was another surprised voice in the audience.

"207 kilometers, as fast as before! The speed of serving twice in a row exceeds 200 kilometers per hour! This is very difficult to do. Zhang Guan is just a track and field athlete. Why is his arm strength so amazing? He doesn't seem to have engaged in throwing events. Could it be this Is it a coincidence? Or is this the way he is good at serving?" Roches vaguely felt a little bit of something wrong.

"It's the third ball. If he still serves the same way as before, it's not a coincidence!" Roches glared at Zhang Guan, while Zhang Guan on the opposite side was ready to serve the third ball.

"I have served the same ball twice in a row. Roches may have found some patterns. This time, we need to pursue the angle more." Thinking of this, Zhang Guan aimed directly at the sideline and sent the ball .

"It's coming! The sideline!" Roches rushed over quickly, but the quality of Zhang Guan's ball was very good, and Zhang Guan's luck was also very good, the ball just flew out against the sideline.

In the rules of tennis, if you press on the line, even if you only press a little bit, it is considered inbounds.

"ACE, 40-0." The referee announced the score.

"It's an in-bounds ball! It just hit the line. Zhang Guan's luck with this ball is really good. Such a fast ball will go out of bounds by a little bit. This time Zhang Guan's serve is the same as the previous two times, extremely fast. On a flat serve, I’m afraid the speed of the ball will exceed 200 kilometers!” Roches looked at the display board, and saw that the speed of this ball was 204 kilometers. Although it was slower than the previous two balls, it still exceeded 200 kilometers serve.

"204 kilometers, as expected, as I judged before, the first two shots are not a coincidence, this is Zhang Guan's good serve method! It's unbelievable, a serve with a speed of over 200 kilometers per hour! But the speed of the serve is not enough. I Now that I have figured out your routine, I can try to catch the next ball." Rocheston was full of fighting spirit.

But Zhang Guan, who was standing opposite, silently recalled the situation of the last ball.

"I used the same serving method three times in a row, so Roches had already judged the right place for the last ball. If he continued to serve the ball in the same way, he might be able to catch the next ball. See Time to add some spin!" Zhang Guan decided to serve a topspin ball this time.

In a topspin serve, the ball is dominated by topspin and supplemented by side spin. Because the ball is in a state of topspin in the air, it will present an arc-shaped flight trajectory that reverses from top to bottom. The arc of this kind of ball is extremely large. , and the hit rate is relatively high.

The racket in Zhang Guan's hand hit the tennis ball hard, making a crisp sound, and then the tennis ball flew out in a rapid spin, drawing an arc in the air.

"The speed of this ball is slower than before! After three consecutive high-speed flat hits, Zhang Guan has no strength now? I will definitely catch it this time!" Roches rushed forward immediately, but then Roches hesitated.

"This ball seems to be out of bounds, um, it must be out of bounds on a flat serve, maybe you can ignore it!" Roches hesitated, the ball was already close to the ground, and at this time Roches also looked at it. It is clear that the tennis ball is topspinning at a high speed.

"No, it's not a flat serve, it's a topspin serve!" Roches yelled inwardly. Topspin is easier to control than a flat shot. If it is a flat shot, it will definitely go out of bounds, but if it is a topspin ball, the force of the topspin will make the tennis ball fall in bounds.

Roches immediately made a remedy, but it was too late to go up at this time, the ball fell in the bounds and spread out rapidly, and Roches failed to touch the tennis ball again.

"Love-game!" The referee announced the result of this game. The word "Love" means zero points in tennis terms, and "Love-game" means to win without letting the opponent get any. One round.

Roches did not win a goal, he was shaved bald by Zhang Guan.

With four consecutive ACE balls, Roches didn't even touch the ball in the entire game.
