Scouting Report
Updated May 19, 2026
Kim Seo-hyeon is a 22-year-old Hanwha Eagles relief pitcher experiencing severe control issues in 2026. After a successful 2025 season as closer with 33 saves and a 3.14 ERA, his performance has deteriorated dramatically. In 2026, he posted a 12.38 ERA over 8 innings with 15 walks, 4 hit batters, and allowed 28 of 52 batters faced to reach base. He was demoted to the Futures League after failing to record an out in a game on May 7, facing 5 batters and allowing all to reach base (2 HBP, 1 walk, 2 hits). Manager Kim Kyung-moon expressed concern about his loss of control and sent him to the 2nd division for extended rehabilitation. In his Futures League debut on May 16, he showed improvement with 1 inning pitched, 1 strikeout, no runs, and better control (10 strikes of 18 pitches).
