A monster fireballer who showed off a fastball of up to 157km in high school. They are finally showing their true value on the professional stage.

Hanwha Eagles Jung Woo-joo has continued his scoreless streak in five games and five ⅓ in August. It is even mentioned as a must-win candidate for Hanwha in second place.

Armed with the spirit and guts of a rookie. At the beginning of the season, the fastball speed, which had fallen sharply, also gained strength.




Sliders honed in the second division are a great force. Hanwha manager Kim Kyung-moon, who met at Changwon NC Park on the 16th, said, `It's very good that I've been practicing sliders in the second division. be noticeably better", he complimented.

As for taking the mound twice a week, "I have no special intention. I'm not going to overdo it. Isn't the pace very good now?" "Professional is completely different from high school days. The six-day game a week is inevitably difficult for high school graduates. After taking a break, the pitching rhythm and balance are very good now."

Jung Woo-ju's inner feelings are full of pride. He "I'm trying to make sure I take this opportunity now. As the results are good in August, confidence grows little by little every time he takes the mound. There's no pressure on my arm, and I don't feel like I'm losing strength," he said with a big smile.

As the body gained strength overall, the fastball pitch improved. "The ball I'm most confident in is the fastball, so I'm using the fastball a lot. I don't feel it because it's summer, but I don't get caught easily and hitters easily. He returned with the utmost emphasis on rest in the second division. Since I had a lot of time to myself, I had a lot of time to think and practice pitching."

Here, the slider that I practiced hard is helping me greatly. He received intensive training from legendary coach Jung Woo-ram in the second division. He has also refined his pitching habits.

Chae Eun-sung and other hitters gave feedback that "'It's obvious when you throw a fastball and slider.'" Perhaps it was seen on the outside that it changed passively when a breaking ball sign occurred. He explained, "I practiced throwing sliders with the same form as my fastball."




There is also a lethal move in the line of seal. Yang Sang-moon, the pitching coach, urged him not to throw a splitter now. It is expected to gradually refine it from this year's final camp. Currently, he sometimes mixes curves with his main slider.

The power of a young bullpen pitcher is shown in the ball power. Jung Woo-joo also overwhelmed opposing batters by throwing a fastball of up to 153km against the NC Dinos on the 15th. In the game against the LG Twins in Jamsil on the 8th, when he took the mound in the 1-1 situation, he roared hot after completing his duties. He said "I thought I was really cool at that moment…"I was mistaken when I saw the video," he said awkwardly. But I tend to keep good memories for a long time. Instead, they don't even search for their names on days when the results are bad.

He struck out 57 in 37 ⅓ innings this season. There are 13.7 strikeouts per 9 innings.

"Three strikeouts are thrilling. There are also situations in which strikeouts are essential. However, I think I'm lucky to throw as soon as I get an autograph. It's because they often take the mound in a relaxed situation, and I think the number of strikeouts will decrease if they play tight games more."

Chung Min-chul, a commentator on Hanwha's permanent absentee legend, also contacted him through a photo shoot. When he was in the second division, he caught him well, which was shaking mentally, and he is also thoroughly passing on pitching know-how to make Jung Woo-joo a complete pitcher.

Existing must-win groups such as Park Sang-won, Han Seung-hyuk, and Joo Hyun-sang are doing well, and they have great confidence in Kim Seo-hyun, the finisher. Jung Woo-joo smiled, saying, `Now I play a role in helping seniors.'

Hanwha has a strong synergy effect as there are many so-called 'light fastball' pitchers, including Moon Dong-ju, Kim Seo-hyun, and Jung Woo-ju.

"It's a good stimulus for me because my older brothers, who are not much older, are throwing such balls. I don't think it's easy to follow the restraint, and there's so much to learn from. I will also work hard on my strengths and become a good pitcher."
