LG Twins Jung Woo-young came to the mound after 5 days and showed clean pitching with 1 perfect inning.
Jung Woo-young climbed the mound in the 7th inning with a 3-2 lead against the KIA held at Jamsil Stadium on the 28th. It was his first appearance after the relief loss against Hanwha on the 23rd.
In a one-point lead situation, Jung Woo-young treated the first batter Socrates with a third baseman grounder in three pitches. All three pitches were two-seam. Lee Chang-jin also caught an outcount with a 3rd baseman grounder on the 4th pitch. All four balls were two-seam.
After two deaths, Seung-taek Han and the match. In the first pitch, he threw a slider for the first time that day, not a two-seam. cheek. Jung Woo-young, who caught a swing and a strike with two seams, lured him with the slider on the 4th pitch, but it was a ball. The 5th pitch is two-seam. He caught a looking strikeout with a strike that curved into the outside border line.
Jung Woo-young threw a total of 12 pitches, 10 two-seams and two sliders. Recently, he has been busy fixing quick motion and adding new crystal spheres.
Starting on the 17th, I started correcting the slide step with pitching coach Kim Gyeong-tae. I tried it in spring camp, but I stopped it because my arm was strained, but in the season, the quick motion slowed down to 1.6 to 1.7 seconds. He became prey to stealing bases for the opposing team, and started fixing the quick motion again. Even when there are no runners, he pitches in quick motion and shortens the time. It is said to have been reduced to 1.3 to 1.4 seconds.
He is also practicing new pitches. Jung Woo-young had a slider rate of over 20% in his first year of debut in 2019 and in 2020. The two-seam restraint gradually became faster in the early to mid-150km, and the two-seam ratio gradually increased as he showed his power. His slider percentage fell to 12% in 2021 and 7% last year. It came close to a two-seam one pitch.
Jung Woo-young threw a four-seam fastball from spring camp this year and set the direction to learn a new deciding ball (breaking ball). Manager Yeom Kyung-yeop said, “If you want to grow further and advance to the major leagues in the future, you must have a falling breaking ball. The slider comes out at two-seam timing and gets caught by the bat.” ㅋㅋㅋ벳
In March, he had insufficient training at the camp because he participated in the World Baseball Classic. There was also a lack of time for new pitch training. During the season, I am doing pitch training at the same time. On the 25th and 26th, he didn’t pitch at all against SSG, and he intensively practiced his changeup in the bullpen before the break and before the game.
Director Yeom said, “I told him to add a curveball and a changeup. The changeup throws a transforming splitter. It’s hard to learn the sudden changeup grip. Similar to a two-seam grip, you just need to spread your fingers a little further.”
Jung Woo-young practiced a new breaking ball with a pitching coach in the bullpen ahead of the KIA game on the 28th. He is still training. He’s not taking it out in practice. Attention is focusing on when he will throw a new breaking ball in practice.
