Eighteen-year-old Korean high school prospect Eom Jun-sang has signed with the Arizona Diamondbacks for a reported $1.5 million bonus, forgoing a projected top-three selection in the KBO draft.
The Diamondbacks announced Tuesday U.S. time that they had signed Eom during the international signing period. A ceremony took place at Chase Field in Phoenix.
Eom played shortstop and pitched for Duksoo High School in Seoul and South Korea's junior national team. In 2026 school games he batted .317 with three home runs, while posting a 2.77 ERA on the mound.
At the 2025 U18 Baseball World Cup he served as Korea's primary shortstop and earned a save with seven strikeouts in 3 2/3 shutout innings. His fastball has reached 153 kph.
Eom aims to become the second Korean to play for the Diamondbacks after Kim Byung-hyun. He is the second Korean teenager to sign with an MLB club this year after Park Chan-min joined the Philadelphia Phillies.
