Born in 2004, it was a splendid professional debut. His highest speed was 157.9 km per hour (based on Sports to Eye). He is a confident rookie who says, “I was under pressure, but I tried to enjoy the tension” behind the game. Such is Kim Seo-hyun, who was nominated by the Hanwha Eagles with the first overall pick in the KBO League rookie draft held last year.

Right-handed side안전놀이터, arm pitcher Kim Seo-hyun took the mound for the first time this season in a match against Doosan Bears in the 2023 KBO League held at Daejeon Hanwha Life Insurance Eagles Park on the 19th. He was the first to be called up to the first team before the game that day after starting as a professional in the second team to catch a jagged ball. The 2nd team’s performance was 5 games, 7 innings pitched, 6 hits (1 home run), 3 runs, 1 run. His earned run average was 1.29.

In the beginning of the 7th inning when the score was tied 5-5, Kim Seo-Hyun, who came to the mound as the third Hanwha pitcher, treated Jose Rojas with a shortstop grounder, then struck out Heo Kyung-Min and Lee Yoo-Chan in succession. The ball that set Heo Gyeong-min and Lee Yu-chan back was recorded at 158 ​​km/h on the electronic board. It was a fast, heavy ball that evoked admiration from the crowd. The youngest’s unstoppable pitching turned the team atmosphere around, and Hanwha won 7-6 against Doosan that day.

Kim Seo-hyun’s first-team debut record was 1 inning, 2 strikeouts and no runs. It was a performance that lived up to his expectations. In particular, with the Trackman equipment operated by the Hanwha club itself, the highest speed was recorded up to 160 km per hour. The KBO League recognizes the speed recorded on the Pitch Tracking System (PTS) operated by Sports 2I as an official record. Kim Seo-hyun’s team senior, Moon Dong-ju, recorded the highest speed of a pitcher in Korea at 160.1 km per hour under the PTS.

In a podium interview after the game, Kim Seo-hyun said, “I didn’t make it to the 1st team because I couldn’t catch the ball, but I think I gained confidence in the 1st team by practicing a lot of fastballs in the 2nd team.” I wanted to enjoy it. He wanted to throw with confidence rather than not being able to throw because he was nervous.” He continued, “I slept a little before the game, and I had a dream about a home run. I was a little anxious about being hit by a home run in the second group, but the moment I got on the mound, I had a strong thought that I had to protect that situation.” Regarding the fastball, he said, “I liked that I heard a lot of compliments about the ball speed and pitching balance rather than speed.”

On the other hand, Dong-ju Moon was absent from the first-team entry that day for a break. He accompanies the team without descending to the second group.
