In professional baseball this season, the ‘light speed ball’ is a craze. Moon Dong-ju (20) and Kim Seo-hyun (19, Hanwha Eagles), who have just become adults, are at the center of this craze.
Moon Dong-ju, who joined Hanwha in 2022, threw 160.1 km against the KIA Tigers in Gwangju on the 12th of last month.
This is measured by the ‘Pitch Tracking System’ (PTS) operated by ‘Sports to I’, the KBO’s official record statistics company, and is the first record achieved by a domestic player in the history of the KBO.
Moon Dong-ju’s one-year junior, Kim Seo-hyun, is no less.
On the 19th of last month, in the match against Doosan Bears in Daejeon, he recorded 160 km per hour based on Trackman, the club’s own measurement system. On the PTS, it was measured as 157.9 km, but the surprise was great.
Even after that, they are intimidating batters with fastballs that reach 160km every time they start. Hitters often miss balls that have not been seen by domestic pitchers.
However, as time passes, differences are appearing in the results of Dong-ju Moon and Seo-hyun Kim.
Moon Dong-ju, who had never thrown less than 5 innings in 5 starts before, collapsed with 7 hits, 3 walks, 2 walks and 7 runs in 2⅓ innings against Incheon SSG Landers on the 13th.
The SSG hitters caught the timing early in preparation for the fast ball and came out swinging foot-and-foot hits. Moon Dong-ju, whose mentality was shaken, came down without being able to complete the third inning, overdoing the 4th pitch.
On the other hand, Seohyun Kim is still impregnable. In particular, against SSG on the 12th, he took the mound in the 9th inning and kept a 3-point lead well, and even made his first professional save.
The fact that those who had a similar start have recently produced different results cannot ignore the difference in position.
Starting pitchers, who must pitch at least 5 innings, have no choice but to expose their weapons to batters as the innings go by, whereas finishing pitchers only have to block one inning with 100% power when the opponent is weak, so the opponent can The feeling of pressure is different.
Also, there is a decisive difference in the pitching form. Moon Dong-joo is an orthodox overthrower, but Kim Seo-hyun is a three-quarter thrower. Even with the same fastball, the rotation and movement of the ball are inevitably different.
This was noted on the field as well. Lee Tae-yang, who is in charge of the pitching team of Hanwha after 14 years of professionalism, evaluated them as ‘completely different’ while assuming that both are talented.
Lee Tae-yang said, “(Moon) Dong-joo’s ball is fast but clean. On the other hand, (Kim) Seo-hyun’s ball movement is so severe that it makes you want to be messy.”
SSG coach Kim Won-hyung, a former great pitcher, had a similar opinion. Director Kim said, “Both are overwhelming in terms of speed, but Kim Seo-hyun’s pitching form is so wild that I think it will be difficult for me to deal with even if I am a batter.”
Hanwha coach Choi Won-ho, who had trained both Dong-ju Moon and Seo-hyun Kim in the past, took a slightly different approach. Although Kim Seo-hyun is younger, it was evaluated that he was better in terms of game management because he had more pitching experience.
Manager Choi explained, “Dong-ju is a player who started pitching properly only in his second year of high school. He doesn’t have much experience yet, so he seems to lack the ability to get through bad times.”
On the other hand, he added, “Seo Hyun-yi has been a good pitcher since middle school. When the fastball is not controlled, he has the ability to catch the count with a breaking ball without delay. This is an appearance that comes out instinctively as experience accumulates.”
However,메이저놀이터 Choi did not forget to encourage Moon Dong-ju.
He said, “Evaluation cannot be different just because one game was poor. Besides, I am only a sophomore in college now,” he said. Advised.
