"Zhang Guan serves, Haas doesn't receive it, the ball falls on the sideline, is it an ace? Or maybe it's an out-of-bounds ball. Out of bounds! The referee decides that it is out of bounds! From our point of view, we can't really see whether the ball is out of bounds or not, but I think the line referee should see it more clearly, which is a pity. ”

"Huh? Zhang Guan wants to challenge Hawkeye? Challenge Hawkeye on the first ball! I don't think it's necessary at all, after all, the game has just begun, and it's only his first serve, although he made a mistake, but Zhang Guan didn't lose the ball, he can still make a second serve. However, if you fail to take on a challenge, you will waste an opportunity to take on the challenge. Unless Zhang Guan is very sure that the landing point of this ball is within the boundary, but with such a fast ball, I think even Zhang Guan, the serve, cannot make a clear judgment! ”

While the narrator was talking, the audience had already turned their attention to the big screen of the scene, waiting for the Eagle Eye system to display the 3D simulation screen on the big screen.

Haas looked at the big screen a little nervously, even if the line referee made a judgment out of bounds, but Haas knew that under the speed of the ball just now, even the line referee who had been staring at the sideline would make a mistake in judgment.

But Zhang Guan looks confident. When the ball landed, the tennis eagle eye instant replay system newly purchased by Zhang Guan in the system had already shown that the edge of the ball was just pressed on the line.

In tennis, as long as the ball is pressed on the line, it is considered to be in bounds, even if it is only a part or even a small part of the line, it will be counted as in the bounds.

A few seconds later, a 3D simulation of the ball appeared on the big screen of the court, showing the tennis ball flying over the net and then landing, and if viewed from a parallel perspective, the ball did indeed appear to have landed out of bounds.

"Does this have to be a throw-in?" Haas was a little relieved, but at this point. The picture on the big screen rotates, and the originally parallel perspective becomes an upward perspective, and a black circle appears in the center, which is the projection display of the tennis ball's landing point.

In the next second, the camera zoomed in, the circle was enlarged, and at this time, you can clearly see that part of the edge of the round black circle is pressed on the line!

"In-bounds! Not out of bounds! Zhang Guan's challenge is successful! The narrator shouted, and at the same time. The scene also remembered the exclamations of the audience.

"Just pressed on the line, so the ball was so lucky."

"It's an in-bounds ball, thanks to Zhang Guan's challenge."

"Zhang Guan is really bold enough, this kind of ball dares to challenge."

The discussion on the scene came and went, and Haas looked at Zhang Guan opposite with some admiration.

"It's really bold, I dared to challenge the ball just now, such a long distance, such a fast ball speed, even the line referee didn't see it clearly. Zhang Guan's challenge really seems to be a gamble! If it were me, I would never dare to challenge this kind of ball. Anyway, the challenge was successful, what luck! ”

Not far away, the line referee also shook his head helplessly. Although this is a misjudgment, it is normal for this kind of ball to be judged with only a little pressure on the sideline, and if you look at it alone, it is normal.

Zhang Guan's face was as usual. He didn't show a look of surprise, this was the result he already knew.

Zhang Guan purchased this tennis Hawkeye real-time replay system in the system, which is completely equivalent to Zhang Guan's private Hawkeye system, of course, there will be no limit on the number of challenges like official matches. Zhang Guan can use it whenever he wants, it doesn't matter how many times he wants to use it, with this system, Zhang Guan can be 100% sure whether the ball has fallen in the boundary, if the ball falls outside the boundary, Zhang Guan will certainly not waste a valuable challenge opportunity, so it can be said that Zhang Guan can achieve a 100% chance of success in challenging Hawkeye.

“15-0！” The referee announced the score, and neither the opposing team nor the spectators disagreed with the decision.

In tennis, a successful challenge does not necessarily mean that you will be able to score, but you may be sentenced to a rematch, and whether you score or replay depends on the referee's penalty. Of course, the referee's penalty also has a certain basis, and the basis is whether the referee interferes with the player's receipt of the ball, if there is no interference with the catch, it will be judged as a score, if there is interference, it will be judged as a rematch.

For example, in this ball, although the referee shouted "OUT", Haas himself was not prepared to receive this ball, so the referee would judge Zhang Guan to score; And if Xavi goes to pick up the ball, which he has already received, but there is an obvious closing action after the referee shouts "OUT", then the ball will be sentenced to a replay.

The match continued, and Zhang Guan began to serve the second ball.

"Whoosh", the tennis ball has flown to the opposite side of the net, this is still a flat serve, the landing point is still the same as just now, it is towards the sideline.

Haas didn't hesitate this time, didn't think about whether it would be a throw-in, he decided to catch the ball first, but the choice of where the ball landed was too extreme, Haas realized that he couldn't catch the ball halfway through, so he began to slow down and stopped.

"It feels the same as just now, it's out of bounds? Or is it pressed to the line again? Haas still had his eyes on the line referee.

“OUT！” The line referee shouted firmly.

Immediately afterwards, Zhang Guan immediately said to the referee: "I want to challenge!" ”

"Woo woo woo woo ......" the audience in the stadium once again let out an exclamation sound.

Haas looked at Zhang Guan in surprise, he didn't understand why Zhang Guan would still challenge.

"If you challenge the first goal, I can understand it, after all, the challenge is successful and gets a good start, which can boost your morale, but this goal is completely unnecessary to challenge again! Your judgment can't be as accurate as the line judge, and you're wasting the opportunity to challenge! ”

……

"Zhang Guan wants to challenge again, two consecutive serve challenges, the challenge just now was successful, obviously Zhang Guan's luck is very good, so this time Zhang Guan can still maintain the luck just now? The speed of this ball is still very fast, but I believe that with the experience of misjudgment just now, the attention of the line referee will be more concentrated, and he should not make another misjudgment! Okay, the Hawkeye simulation screen is out! ”

As soon as the narrator's voice fell, the parallel perspective on the big screen had changed to a vertical perspective, and the edge of the black circle could be seen pressed against the white edge again.

"Oh! Oh my goodness, inbounds! Zhang Guan's challenge was successful! Another success! It's just the line again! It's so exciting, it's so exciting, it's so thrilling! The narrator said with a look of amazement.

And in the audience, this time there was a burst of cheers and applause. This kind of continuous ace ball makes the pace of the game very fast, and the viewing is of course far less than the player's back-and-forth multi-shot hold, but the process of the Hawkeye challenge is very exciting, for the audience, the Hawkeye challenge is like the moment when the screen cup is opened after the game is bought and left, and the tension is even stronger than enjoying the game process. And the success of these two consecutive extreme challenges obviously satisfies the audience's desire for tension and excitement.

……

The cheers on the scene slowed down the game a little, and the referee did not urge Zhang Guan to continue serving, firstly, the cheers of the audience would affect the players' judgment of the ball, and secondly, the referee also gave the players on both sides a buffer time to adjust their mentality.

"The challenge was successful again, and the challenge was successful again!" Haas's expression was very strange, and he couldn't help but look at the line referee on his side.

And the line referee also felt a little embarrassed when he noticed Haas's gaze. As a line referee, his main task is to judge whether the ball is out of bounds, but two consecutive judgment errors also made the line referee disgraced.

"I've made two mistakes in a row, I have to be cautious, if I miss the wrong goal again, it's really embarrassing!" Thinking of this, the line referee's eyes widened and he stared straight at the sideline.

The voices in the audience gradually subsided, and Zhang Guan began to serve the third ball. (To be continued.) )
