"It was just a desperate heart, a desperate need to live."

One of Lotte Giants' starting pillars has become more reassuring. Kim Jin-wook, who will play as the fourth starter this year, is equipped with a change-up of 'new weapon'.

Earlier during Taiwan's spring camp, Kim Jin-wook "I'm preparing for a change-up with a new pitch, but it's still a secret." If I feel confident that I can use it in practice, I will reveal it then."




The new weapon was finally unveiled through the exhibition game against the LG Twins. It's a circle change-up. I've been practicing for a long time, but it's the first time I've shown such a high degree of completion in practice.

Kim Jin-wook, who met at Sajik Stadium in Busan on the 13th, said "It's good for stealing the batter's timing, and you can throw it in the strike zone." I'll have to practice more, but I'm okay at this moment."

What's impressive is that Ryu Hyun-jin of the Hanwha Eagles taught him how to change up. Kim Jin-wook explained, `In September last year, I visited Ryu Hyun-jin at the last game of the season and learned about it.'

Kim Jin-wook is loved by his seniors for his bright greetings and wrinkle-free personality. However, there was no special relationship with Ryu Hyun-jin, who had a different team and a large age difference. Who connected the two.

"There was no one like that. We've never seen each other before. Daejeon Stadium is equipped with a bullpen. He recklessly went to the opponent's bullpen. I was desperate and desperate. I was just asking if I could get a hint to practice during the offseason, but you answered so kindly. The theory and the senses were different from what I had thought."

Kim Jin-wook's complete change-up is a little different from Ryu Hyun-jin's. Starting from Ryu Hyun-jin, he learned from So Hyung-joon, who was training together in Japan, and added additional advice to Lotte foreign players Davison and Barnes in this year's spring camp. In particular, the advice of the two was crucial, saying, "You have a high arm position, so it would be better to actively use your middle finger and ring finger to throw it."




However, Kim Jin-wook, who was explaining his realization by showing his grip on holding the ball himself, said, `The hint that became the starting point and the flexibility that became the first step were the greatest. It's not just a changeup. I also heard about know-how on how to control the level of supply. I really want to do well this year," he said, reiterating Ryu's help.

"It feels a little similar to when you throw a knuckle curve." With the strength of the ring finger, the wrist can come out naturally. I also looked at the trackman's figures, and I learned the feeling by continuing to throw. It's been three to four years since I've tried to learn the changeup itself, and if you look at this situation alone, it's about two to three months. There is no awkward feeling at all now."

It takes three months to learn and learn for the first time, and two to three months to play it properly in practice. 'A man who is serious about baseball' This is a glimpse of Kim Jin-wook's efforts.

Kim Jin-wook played 84 ⅔ innings, the most since his debut last year. Lotte's 4th starter is likely again this year. It is trying to utilize various types of pitches by adding changeups to existing fastballs, curves, sliders, and fork balls that were thrown occasionally. Regarding the elbow that was in question last year, he stressed that there is nothing wrong with it now.

Main catcher Yoo Kang-nam was also surprised when "(Kim) Jin-wook received a change-up from Taiwan for the first time. It's because I like it so much. He threw well right away in the game because he thought it was done. I thought I really put in a lot of effort, he encouraged.
