Overview
- The Diamondbacks completed the signing of 18‑year‑old Jun‑sang Eom and held a public ceremony at Chase Field on June 16 where he took batting practice with major‑league players.
- Multiple reports say the deal includes a signing bonus of about $1.5 million, a seven‑figure sum that reflects his status among South Korea’s top amateurs.
- Eom is a two‑way shortstop and right‑handed pitcher by background but Arizona’s evaluators have indicated they will emphasize his development as an infielder and batter.
- Scouts note Eom’s 6‑foot‑1, 205‑pound frame, current 2026 high‑school hitting numbers, and a fastball that has touched about 95 mph along with a slider and splitter.
- Eom declined entry into the KBO draft to sign in MLB, making him a long‑term project who could shape future Korean recruiting and who would be only the second South Korean to play for the Diamondbacks if he reaches the majors.
