"The tiger is coming when I say it. (Oh)Wonseok, come here."

KT Wiz manager Lee Kang-chul, who was bragging about Oh Won-seok, called out the passing player. It was none other than Oh Won-seok.

KT Wiz manager Lee Kang-chul's expression looking at Oh Won-seok (24) is full of proud smiles. The master trainer has created another work. The young left-hander acquired through trade has now grown into a leading native starter in the league.




Although he became a losing pitcher against the Lotte Giants in Busan on the 26th, manager Lee Kang-chul said, `Oh Won-seok threw well.' `I'm upset that it keeps getting twisted this year. "I had the conditions (to win), but I got a home run from behind, and yesterday the game ended with a defensive error."

Still, he has his first 10 wins (seven losses) and an ERA of 3.27. It has already filled the regular innings twice, and this year is the fifth time it has exceeded 100 innings. Sufficient experience is soon leading to growth.

"We gave too many free steals at the beginning of the season. They gave me second base and third base, so I made them practice separately. Look at the last two games, the runners can't even move. He was desperate for it himself."




Manager Lee Kang-chul said, `If a runner goes to first base, I was worried because of the stolen base. Why didn't he do it when he said, "I won't take it anymore because I changed it?", he raised his voice.

When I was in SSG Landers, my weakness was that my physical strength decreased toward the second half of the season. I lost 7kg of weight during the summer.

This year is completely different. The back pain, which I was worried about, has also completely improved. Coach Lee Kang-chul laughed, saying, `I paid a lot of attention to management.'

"The throwing balance is different. Just by looking at it, you lose unnecessary power and look comfortable. In the past, when I joined forces, the speed was in the late 140km range, but it was not constant, and after three to four times, the speed dropped sharply, the control was not good, and I was easily exhausted. It's now in full control. "He threw it easily in the early 140km and early, threw it up to 149km when needed, and that's how much confidence he gained."

What do you think of Oh Won-seok. He "Before, the balance of the pitch was shaky, so I used to use my strength when I threw the ball. Now, the balance has become constant and the pitching form has been simplified, so I feel like I'm throwing it a little more naturally."

Coach Lee Kang-chul said, `A good balance definitely takes less strength. It's not about throwing hard. If your lower body supports you, you can throw more than 100 balls. There are only 30 to 40 power throws out of the 100 pitches, so "Oh Won-seok suddenly throws 147, 148km when he tries to change it because it is six times these days. Do you need it?? You can throw it. From now on, he has to throw up to the seventh inning. These days, free stolen bases are also complimentary, so it's so nice," he said with a big smile.

Another work by director Lee Kang-chul, Cho Hyung-joon, also exceeds 150km when needed. He is a sample player of 'Don't try to throw too hard', which the head coach always emphasizes. This is why he praises, saying, "I know how to fix shortcomings, and if you teach me, I will quickly absorb them."

"What kind of pitcher will Oh Won-seok and So Hyung-joon be next year? I'm looking forward to it more from the manager's point of view."
