Overview
- The Arizona Diamondbacks finalized a deal for 18-year-old Eom Jun-sang during the international signing period, a move confirmed by the team and his Seoul-based agency.
- Multiple outlets reported the bonus at roughly $1.5 million and Eom participated in an on-field signing event at Chase Field where he took batting practice with big leaguers and showed notable power.
- Eom arrives as a true two-way high-school standout from Duksoo High School and South Korea’s U18 national team, with 2026 marks of .317/.443/.556 at the plate and a fastball that has touched about 95 mph.
- Diamondbacks evaluators described him as a strong defensive shortstop prospect with batting upside and have signaled they will prioritize his position-player development while leaving any pitching role as a secondary, longer-term option.
- The signing adds to growing MLB interest in top Korean amateurs and underscores a pattern of teenagers choosing MLB contracts over entering the KBO draft, a trend that could shift the domestic talent pipeline.
