100% challenge success

"This ball is out of bounds! Wait, Zhang Guan wants to challenge Hawk-eye. Can he challenge again? This ball looks like an out-of-bounds ball. Ah! In-bound! In-bound! Pressed on the line! Zhang Guan's challenge is successful!"

"Zhang Guan challenged the Hawk-Eye again. If I remember correctly, this is his ninth challenge to Hawk-Eye today. Among Zhang Guan's first eight challenges, all of them were successful. Eight consecutive challenges to the Hawkeye, and he succeeded, I think this can be regarded as a world record! Oh my goodness! Zhang Guan's challenge was successful again! The ninth time! The success of nine consecutive successful challenges! And it was still in a set game here! It's amazing!"

"Out of bounds! Should Zhang Guan challenge? Oh, he challenged! Zhang Guan's tenth challenge in this game... Zhang Guan's challenge was successful! In a set game, he challenged the Hawk-Eyes ten times in a row!"

"For the eleventh time, the success of the eleventh consecutive challenge! The camera aimed at the line referee, the line referee's expression looked very embarrassed, he once again made a misjudgment! I think Zhang Guan's continuous challenge of the Hawk-Eye puts great pressure on the line referee!"

"Inside? Oh? The head referee changed the ball to out-of-bounds! Will Zhang Guan challenge the Hawk-Eye! Sure enough, Zhang Guan challenges Hawk-Eye for the twelfth time! Zhang Guan feels that the face of the line referee was not enough. Do you want to face the referee? I don't know if Zhang Guan can see it better than the line referee, but since the referee changes the sentence, I think he will see it! Can Zhang Guan challenge the success this time ... Um, from this perspective, it is out of bounds, but we need to zoom in on the screen to see it more clearly, oh! God, the line has been pressed, and we can see it clearly after the screen is enlarged. It is indeed a little bit of a line! This is an in-bound ball! Zhang Guan's twelfth challenge was successful!"

"Thirteenth challenge! Successful again! My goodness! Thirteen consecutive challenges were successful. This is incredible. I am even beginning to wonder if the Hawk-Eye system is Zhang Guan's family member. Success! Haas has no chance to challenge unless he can stick to the tiebreak!"

In the next few games, the challenge became the main axis of the game. Zhang Guan constantly challenged and continued to challenge success, and every time Zhang Guan challenged, there was extremely warm cheering from the audience on the scene. The audience gradually changed from looking forward to the result of the challenge to looking forward to Zhang Guan launching the challenge. At this time, most of the audience have no intention to continue to appreciate the game, but instead stare at the referee, waiting for the referee to give a disadvantage to Zhang Guan. The penalty of the crown is waiting for Zhang Guan to challenge Hawk-Eye.

They saw Zhang Guan serve, then the line referee shouted, "OUT!"

"Challenge! Challenge! Challenge!" The audience stood up and shouted in unison.

Zhang Guan smiled a little embarrassedly and challenged the referee's request. At the next moment, the audience immediately swelled. The result of the challenge has not yet come out and the audience has begun to cheer.

The referee also felt very helpless. He is also a man with more than ten years of referee experience. He can fully feel that the audience on the scene has been excited. This excitement is even no less than the Grand Slam final.

The 3D simulation picture was displayed on the big screen. Zhang Guan was right. He won the challenge again. The referee ruled that Zhang Guan won the ball.

"Congratulations to Zhang Guan. He won this point through a successful challenge to Hawkeye, and also won the game. Now the scores of the two sides have reached 4-3, followed by Haas' serve. Let us look forward to the eighth game between the two sides!"

At this time Haas' expression was a little dignified, because his challenge opportunities had been used up, and Zhang Guan even challenged Hawk-Eye for the 14th consecutive success. That is to say, in the next game, Zhang Guan still has a chance to question the referee's penalty, and he is no longer qualified to question the referee's penalty. Even if the referee's penalty is not good for him, even if the referee misjudges, Haas will be helpless. Only when the first set is dragged into the tie-break, can Haas get an additional chance to challenge!

In the eighth game between the two sides, Haas served.

15-0, 15-15, 30-15, 40-15, 40-30, evenly divided, Haas, occupied first, evenly divided with Zhang Guan...

In the eighth game, he scored the 11th ball. Zhang Guan was sentenced out of bounds on a return, but Zhang Guan challenged Hawk-eye to make the referee change the sentence and got the breaking point for the first time.

On the next goal, Haas made a move and the second serve was relatively conservative. Zhang Guan took the initiative after a few shots and then used a wonderful net to hang the ball to win the game.

"Broken, Zhang Guan's successful break! This is also the first break in this game, but for Haas, this time it is deadly to be broken by Zhang Guan! Because the current total score is 5-3, below is Zhang Guan's serve, if Haas can't finish the break, then he will lose the first set game! However, we all know that Zhang Guan's serve is very powerful. So far, Zhang Guan hasn't lost any serve yet in this game!"

The narrator's voice seemed to condemn Haas' death sentence, but Haas didn't give up. He was still fighting, still running, and still trying to catch every ball.

However, Haas' efforts did not change the final result. After 40-30, Zhang Guan won the first set of the game with a perfect serve of 207 kilometers per hour.

...

Haas sat on the sidelines, his expression full of depression. He looked at his watch and it was more than ten o'clock in the morning, that is to say, in the previous game, the two sides played for more than an hour.

"Most of the time is spent challenging Hawk-Eye!" Haas looked at the camera of the Hawk-Eye system all over the venue with annoyance, "It's wrong to lose! I didn't make any mistakes and I played quite well. Yes, the result was so inexplicably lost! The key game was broken, this damn hawk-eye system, why can Zhang Guan succeed in every challenge? I have recognized three or five consecutive successful challenges. Why can he be successful even with more than a dozen challenges! And there are so many goals that are so extreme, it is not clear to the naked eye, how can Zhang Guan judge whether it is in or out of bounds?"

"However, the success of a dozen consecutive challenges is impossible. It was impossible to be blind. Just now there were many balls in the game. It seems that there is a good chance to challenge, but Zhang Guan did not do that. There is a basis, he can see clearly! With such good eyesight, why not practice shooting, why is he playing tennis!" Haas was a little irritated, he looked at his watch again and said to himself, "How come the next game still didn't start!"

...

The interval between these two games is indeed long because the staff at Vodafone Stadium is testing the stadium's Hawk-Eye system.

"The Hawkeye system has been restarted and we have not found anything abnormal."

"I just re-simulated each of Zhang Guan's challenges again, and the results are the same as before. Our Hawk-Eye system has no problems."

The head of the technical department suddenly breathed a sigh of relief, "As long as it is not because of a problem with our system. I'm really worried about a misjudgment because of a problem with our system. But then again, a dozen challenges, how did Zhang Guan succeed in all of his challenges?"

"I think maybe it's because Zhang Guan is superior in vision! I remember there is a comic book in the United States that writes about killers. Those killers can hit targets from thousands of kilometers away! Maybe Zhang Guan also has a similar ability!"
