Roh Si-hwan, the Hyundai Unicorns' 27-year-old right-hander, entered an 11-year posting agreement with Major League Baseball worth ₩30.7 billion ($21.8 million), launching a 30-day exclusive negotiating window that ends in mid-January. The Unicorns receive the posting fee regardless of whether Roh signs; MLB clubs now bid contract offers directly to his representatives.

The deal represents the longest posting term announced under the current KBO-MLB framework, which traditionally sees two- to five-year windows. Roh posted a 3.42 ERA across 187 innings last season with 169 strikeouts, walking 41. His four-seam fastball sits 94-96 mph, and he throws a plus-changeup that scouts compare favorably to Kwang Hyun Kim's 2020 Cardinals work. The Unicorns finished fourth in the KBO standings; Roh's departure removes 32% of their rotation innings from last year's playoff push.

The 11-year structure matters because it locks the Unicorns into receiving the posting fee now while deferring replacement cost over a decade-plus horizon, essentially a financing mechanism for teams operating under Korea's soft luxury-tax threshold of ₩11.5 billion. If Roh signs a $60 million MLB deal—the whisper number among Pacific Rim agents—the Unicorns net the posting fee and avoid paying his arbitration years, which would have started in 2026 at an estimated ₩1.8 billion annually. The structure also signals the Unicorns expect material revenue growth from their Incheon stadium rebuild, scheduled to complete in 2027, and need payroll flexibility now.

Three teams are circling: the Padres, who employed Roh's former pitching coach from the 2022 Korea national team, the Mariners, whose front office has scouted him in 18 of his last 23 starts, and the Mets, who need a back-end starter after missing on Yoshinobu Yamamoto. The Padres have $14 million in projected luxury-tax space before hitting the second threshold; Roh's camp is reportedly seeking $5-6 million annually over six years, which fits their budget if they non-tender one of their current relievers. The Mariners' interest depends on whether they move Luis Castillo by the February trade deadline; if they do, Roh slides into the third rotation spot and Jerry Dipoto avoids paying the $22 million Castillo salary in 2025-26.

Two items to watch: MLB's international committee meets January 18 to review posting-fee structures, and if the Unicorns' 11-year model becomes standard, expect KBO clubs to front-load contract demands during the 2025-26 offseason before any rule changes. Also, Roh's agency, Octagon Korea, represents three other KBO pitchers whose contracts expire in 2026—if he signs for $50 million-plus, those players will push for earlier posting windows rather than wait for free agency at age 29-30.

Roh's physical is scheduled for the third week of January in Arizona. If he passes, the signing happens within 72 hours and the Unicorns begin their ₩30.7 billion spending plan, which league sources say prioritizes a Cuban shortstop currently in Mexico's winter league.
