KBO Asks MLB to Post Star Slugger Roh Si-hwan

This starts a 30-day MLB negotiation window that could lead to an MLB contract triggering a tiered release fee to the Hanwha Eagles.

Overview

The Korea Baseball Organization formally asked Major League Baseball to post Roh Si-hwan after the Hanwha Eagles accepted his request, a step reported on Saturday, Oct. 31, 2026.
Once MLB notifies its clubs the posting window will open at 8 a.m. Eastern Time the following day and run for 30 days during which any of the 30 teams may negotiate with Roh.
If Roh signs with an MLB team that club must pay the Eagles a release fee calculated as 20% of the first $25 million, 17.5% of the next $25 million, and 15% of any amount above $50 million.
Roh is a high-volume power hitter who has totaled 116 homers since 2023 and posted 29 homers with a .283/.360/.505 line in 2026, and he signed an 11-year, 30.7 billion won KBO deal that takes effect in 2027.
Roh’s agency said he applied to pursue a long-held MLB dream, and his availability could shift offseason plans for MLB clubs though his posting window could be affected if a league lockout begins after the collective bargaining agreement expires on Dec. 1.
