Even a surprise knuckleball… 156km For Kim Seo-hyun, the 2nd group is narrow, ERA 1.29 ‘powerful fight’

The presence of new players in pitching, such as Song Young-jin (SSG), Park Myung-geun (LG), Lee Ho-seong (Samsung), Moon Hyun-bin (Hanwha), Kim Min-seok (Lotte), Kim Dong-heon (Kiwoom), etc. It’s heating up. Among them, pitcher Kim Seo-hyeon (19, Hanwha), who was nominated as the first overall, has yet to debut.

Kim Seo-hyun, who went down to the 2nd team ahead of the opening, started the season in the Futures League. During the demonstration game, he threw a fastball of up to 158 km and played hard with an average ERA of 1.80 in 5 games and 3 holds, but Hanwha sent Kim Seo-hyun to the Futures team in order to systematically develop players. As a pitcher, not only skills were required, but also a training process to build a body capable of withstanding fastballs. Hanwha coach Carlos Subero was also in no hurry, saying, “It is not too late to call up after growing up at Futures for a certain period of time.” 

After starting the Futures League on the 4th안전놀이터, Kim Seo-hyun, who made relief mounds in 5 games, took 1 hold and gave up only 1 run in 7 innings. 1.29 ERA. He struck out 11 while allowing only two walks and only one walk. In the demonstration game, the so-called ‘bolsambi’ was not good with 4 strikeouts, 4 walks and 2 walks in 5 innings. 

His only concession was a solo home run hit by Hong Seong-ho against Seosan Doosan on the 8th. At the first home run of his 19-year-old baseball life, Kim Seo-hyun said, “It was the first time he had hit a home run, but he looked at the flying ball. He said, “It was a mistake that went into a high course, but he thought he had to reduce it in the future.” Other than that, there are no flaws. 

In the most recent match against Ganghwa SSG on the 16th, he played multiple innings with 2 innings, 1 hit, 2 walks, 2 strikeouts and no runs. Kim Seo-hyun, who came up in the 6th inning following starter Kim Jae-young, got a right-handed hit from Kim Gun-woong, but Choi Hang was hit by a fly ball to center fielder and Ko Myung-jun was grounded to second base, leading to a 4-6-3 double kill. In the 7th inning, he struck out Lee Heung-ryeon and Cho Hyung-woo in a row, and Choi Yu-bin was put out with a shortstop ground ball. 

Only 16 pitches in 2 innings. He threw a similar ratio of fastballs (8) with a maximum velocity of 156 km, as well as curveballs (5), changeups (4) and knuckleballs (1). 

In particular, his knuckleball command stood out. He once threw a knuckleball against Monsters of the entertainment program “Strongest Baseball” as a member of the youth national team last year, and he threw it in an official game for the first time in a professional game. He threw a knuckleball that went into the strike zone against Cho Hyeong-woo in the 7th inning, and a foul came out. 

Kim Seo-hyun, whose position this season is the bullpen, is working on simplifying the pitching repertoire by refining certain types of pitches. In the match against Doosan on the 8th, he threw 2 innings only with a fastball and a curve two-pitch. However, Kim Seo-hyun, who said, “I want to throw a knuckleball someday,” could not completely block his will. 

Hanwha’s bullpen is weakened with 4 come-from-behind losses, including 5 blown saves, the most in the league, and 3 overtime losses. The relief ERA is 4th (4.45), above the league average, but the bullpen innings (60⅔) is the most among 10 teams amid Birch Smith’s injury vacancy. In a situation where the burden of the bullpen is increasing, attention is also focused on the timing of Kim Seo-hyun’s call-up to the first team.
