Hanwha Eagles’ super rookie Kim Seo-hyun is equipped with the latest fashion harness.
Seohyun Kim took the mound as a pitcher at the end of the 7th inning following starting pitcher Minwoo Kim against Doosan in Jamsil on the 3rd. Heo Kyung-min and Rojas caught ground balls side by side, and Jang Seung-hyun struck out three pitches. He threw 8 out of 11 pitches as strikes, and his highest velocity was clocked at 153 km/h.
The second ball he threw at Jang Seung-hyeon that day caught the attention of fans. Kim Seo-hyun, who received the judgment of a looking strike with a slider on the side of the first pitch at 130 km/h. The second pitch also threw a breaking ball, but the movement was unfamiliar unlike the previous breaking ball. In the pitch tracking system (PTS) provided by Sports 2I, the official KBO league record company, it came out as a slider at 137 km/h, but unlike the previous ball, it bent outward greatly.
After the game,안전놀이터 Kim Seo-hyun said, “The two pitches I threw at Jang Seung-hyun were sweepers.” He said, “Isn’t the sweeper on the rise these days? Coach Rosado is pushing within the team. (Han) Seung-ju hyung and I are throwing it.”
He continued, “I practiced the sweeper for about three days. Coach Rosado said, ‘Your mentality seems to be a bit great.’
The sweeper is a variation slider that is currently trending in MLB. In Korea, Ohtani is famous for the ball that caught Trout in the 2023 WBC final.
There are three major differences between sweepers and sliders. These are grip, ball movement, and hitting results. The sweeper throws not much different from the slider, but as the name suggests, the index and middle fingers are held more over the seam to allow for a more sweeping throw. The movement flows more horizontally with the sweeper and vertically with the slider. The batting result shows that the sweeper induces more fly balls and infield fly balls than the slider and allows fewer strong hits.
Kim Seo-hyun said, “(Sweeper) is not used to it yet. I plan to keep throwing it.” It’s fun. It’s fun to learn the breaking ball. I think it will continue to change in the future. The form may become constant someday, but I wonder if pitches will come or go one by one.”
A rookie pitcher throws a light-speed ball approaching 160 km/h, followed by the latest MLB breaking ball. The feeling of his hand, which was equipped with a breaking ball in three days, and the boldness recognized by the pitching coach are a bonus. Perhaps we are watching the debut season of a historic pitcher.
