Grand Slam

The next day, I saw both my parents and my coach and came to the Academy with amazing news in front of the quartz and Jinhee.

“Contract?”

The clerk presented several documents in front of marble and Jinhee.

“Yeah, actually, I'm still kind of late. Normally, juniors would be able to sign contracts, but stone and Jinhee had finally entered the competition with their faces on. But since Future has a winning streak, the conditions aren't so bad. ”

At the words of the clerk, he fell into his mind, and Jinhee was staring at him as she always did. It's because I believe in the choice of stone.

“Sam, we're underage, and we don't have the knowledge or the ability to take responsibility for our choices. ”

Sam, the clerk, replied seriously to the marble.

“Of course, nevertheless, the reason we're showing you this contract is because this contract has been purely drawn to your ability. I wanted you to know that. Of course, you have to consult with your guardian, but in the future, you have to make all the decisions by yourself, floating around the world alone. No matter how many people you carry around with you, this doesn't change. ”

At Sam's words, marble and Jinhee nod. That's a correct phrase. Sam saw such marble and Jinhee.

“First of all, a tennis player can make about three separate contracts. In other words, you can do shoes, clothes, rackets all separately. But in the case of Nike or Adidas, there is often a contract between shoes and clothes. Usually that's almost how it goes. ”

Sam explained slowly and calmly.

“Outside the racket, performance itself is not that different. The racket is grinding according to your preference. As a result, many athletes choose between Nike and Adidas for their clothes and shoes, while racquets choose to suit their tastes. Nike and Adidas have similar conditions, so you just have to pick out pretty clothes and shoes. All that matters is the racket. ”

“Racket?”

Jinhee asks. Quartz nods as if he's guessing something. Sam made eye contact with Jinhee and explained.

“Players are very different, so each racket fits their own hand... It's fun to try different rackets and find the one that suits them. Some wise coaches insist that if they're good, they're good at whatever racket they're good at, but that's also old school. Racket is science now. Rackets are a great tool for athletes to extend their hands and to supplement their weaknesses. ”

Sam picks up the fan and starts explaining by drawing on the paper on his desk.

“The racket's specifications can simply be expressed in five ways: First, head size is important. Units are square.”

“It's easy to hit when you're big! ”

Jinhee smiled brightly and said.

Sam smiled and gave a more detailed description.

“Modern tennis rackets range in size from 90 to 120 squares. You can hit the ball easily with a large size, but you can't concentrate your strength. On the contrary, if the ball is narrow, it is difficult to match the spot. That's why Balance, another spec, is important. ”

Quartz translated Sam's words little by little to Jinhee. You can only understand the meaning, but you need to have all the basic knowledge of the racket. Sam paused and glanced at such marble and Jinhee.

“Balance is easy to feel. It's the difference between the center of gravity on the racket's head and the grip, so you can feel it as soon as you pick it up. Usually in mm. For example, 300 mm has a center of gravity of 300 mm from the handle of the racket. If the head is heavy, it is called the head heavyweight, if the center of the racket is centered. If the weight is focused on the grip, it is called the head light. ”

The quartz translated diligently for Jinhee, thinking that Sam drew a really good racket while looking at it.

“You were talking about the size of the head, right? Since it is hard to hit a strong ball when it is large, it is often head heavy balance when crossing 110 squares. Conversely, if the head is narrow, it is often head light for relatively easy operation. So you've been talking about head size, balance? ”

“Yes.”

“Next we'll talk about weight. Strung weight means the weight as it is with the racket wrapped around it. Swing weights are the weights we feel when we swing. The principle is simple: a large head, heavy-balanced racket weighs less than the racket itself, but the swing weight is heavy. Why is that?”

Jinhee who heard the interpretation of marble tilted her head.

Sitting there, I swung my arm, and then I got up and started swinging all kinds of things. Sam and marble waited quietly to see such Jinhee.

“Ah!! ”

Jinhee sighs as if she had swung her Balinese swing.

“Is it because the distance from your hand is heavy? ”

“Yes, because the weight of the swing is heavy, many manufacturers try to make the weight of the racket lighter. Conversely, heavy-gripped head light rackets are smaller in size and the racket itself is heavier but feels lighter on the swing. ”

Quartz stroked Jinhee's head and praised her for doing well.

Sam speaks.

“Now I've said four things. Racket head size, balance, weight, and swing weight. All of this is connected. One element is the Sam that defines the other. One last spec and we're done. ”

Sam drank a sip of water to see if his throat was burning.

“The last one is about string patterns. In fact, compared to the above four specs, it's hard to feel. Because it's separate from other specs, it's not an organic component. String patterns are of different types depending on how many lines are tied: main (vertical) and cross (horizontal). There are two big ones. One is an open pattern and the other is a denim pattern. There are fewer open lines, there are many dental patterns. If you ask me how many lines each one is, it's hard to answer. It's so diverse. Oh, 18 by 20 is definitely a dental pattern. ”

“Hard.”

Even marble can't explain this part clearly. Nevertheless, Sam tried to teach me as easily and kindly as possible.

“If there are fewer lines, the ball is scratched well because it is wide between the lines. That's why they say the spin works. Conversely, more lines means fewer spins, but more advantages with accuracy. However, spin is the element that determines a player's swing form or habit, and the string pattern should allow the player to determine the type that suits him/herself through a long study. ”

“Phew, it's long. ”

Jinhee nodded her head as if she understood.

“Oh, right. ”

“Are you still there? ”

Jinhee stared at the quartz and springs alternately, hating Jinhee.

“Strings are commonly referred to as guerrillas, but they're also important for the fabrication and fabrication of guerrillas. It's very important to know the intensity of the string in the racket. As the general public needs finesse in unimaginable areas, let's get to the point. ”

After explaining, Sam goes to his desk and sits down to pull something out of Juju Island.

“Wow! It's beautiful! ”

I had to hold it in my arms and bring it back, but it was a ten-piece racket with a colorful appearance.

“I can't say it's all racket makers, but it's mostly racket makers. Wilson, Head, Babolat, Prince, Dunlop, Prokennex, Pacific, Tecnifibre, Yonex, Volkl. Let's see... ”

Sam took out a racket and showed it to Jinhee.

It was a beautifully painted racket in blue and white.

“Oh! Hey, this looks like mine. ”

Sam smiles bloody and says.

“As you've been using our Academy for years, let's look at the accumulated data. Well, Jinhee, I remember that you need a very resilient racket to maximize your lack of stroke power. We have to consider manipulation for the ease of Bali, a specialist. You'd better grip the head size before and after 100 squares and balance a little more than Even Balance. If you look at this brand, it looks like this racket, but it's a little shinier, right? ”

Jinhee is stunned by Sam's reasoning.

“Oh, how did you know? I thought you were seeing Holmes. ”

Sam looked at the marble this time and said,

“Hey, you picked it out for me, didn't you? ”

“What? Really? ”

The stone, which was embarrassed by the intensive gaze of the two, scratched his head.

“It was just pretty. ”

I made up my mind, but Jinhee and Sam didn't believe me.

Jinhee ran to meet him and hugged him. And then I kissed her.

“Thank you. Only marble, indeed. Mmm, that way!! ”

“Ugh... I've only learned evil from my mother. ”

I couldn't help but notice Sam. because it is too trivial.

Sam glanced at the rock, met its eyes and said.

“We'll have to look at the records, but maybe we picked the racquet for Jinhee, not just for the brand. Amazing.”

“I'm ashamed, Sam. Anyone can do this. What...? ”

“Hey, marble, what do you like about your racket? ”

Sam asked about the taste of marble.

“Extreme tour racket. ”

The quartz said without a moment's hesitation.

Tour-type rackets are rackets that are small, heavy and have a head light balance.

“It's a little classic. But so far, you've used a normal racket. ”

“We've been replacing the racket with the speed at which the body develops. ”

At the words of the rock, Sam was creeped out.

‘It was different when I was very young, but it was also... ·’

Sam shakes his head and gets up from his seat and says, The attitude is that the explanation is over.

“Now you get the idea of the racket, right? Most brands usually have multiple lineups waiting for the player to choose from. They say there are pros and cons for each brand, but in fact it doesn't make a difference. You can choose a brand that is psychologically stable, a brand that you love, a brand that looks pretty… or a brand that has striking conditions. ”

“Sam, let's get something straight. So you have contacts with me and Jinhee? ”

Sam goes to the office table, smiling and calls someone.

“… just come up. ”

Sam relaxed and enjoyed the curious expression of marble and Jinhee, whispering in a very charming voice.

“You know, a lot of that, too. ”
