South Korean pitcher Song Sung-mun signed a $13 million contract with the San Diego Padres, the team announced Tuesday, marking the third KBO-to-MLB pitching deal completed since November. The 27-year-old right-hander posted a 2.59 ERA across 180 innings for the Kiwoom Heroes last season, walking fewer than two batters per nine.
The contract includes $8.5 million guaranteed over two years with a club option for 2027 at $4.5 million, structured to keep Song under luxury-tax thresholds while the Padres evaluate extension talks with Dylan Cease. Song throws a low-90s sinker with a split-change that induced a 61% groundball rate in the KBO, a profile San Diego's front office values for Petco Park. He arrives with no posting fee because Kiwoom declined to extend him a qualifying offer, leaving him a true free agent under NPB-KBO-MLB labor agreements revised in 2023.
The signing adds to momentum that began when the Padres played two games in Seoul last March, drawing 86,000 across two dates and generating $4.2 million in ancillary revenue for the club, per internal documents reviewed by team executives in October. Samsung Electronics, which sponsored those games, has since opened preliminary discussions about a helmet patch deal worth an estimated $18 million annually, contingent on San Diego maintaining a Korean-born player on the active roster through 2026. Song's contract timeline aligns exactly with that sponsorship window. The Padres declined comment on sponsor negotiations.
Korean talent acquisition has become a defined vertical for MLB teams with Pacific exposure. The Dodgers signed Ryu Hyun-jin and later Yamamoto Yoshinobu; the Mariners built a front-office Korea desk in 2021. San Diego now employs two Seoul-based scouts and a translator who previously worked for the Heroes. Song is the fourth Korean pitcher the Padres have scouted since 2022, the only one they signed. The decision followed a private workout in Incheon in late November attended by GM A.J. Preller and pitching coordinator Ben Fritz, who watched Song throw 52 pitches across three simulated innings. Fritz told colleagues the split-change was "major-league ready."
The deal also reflects broader KBO economics. Korean teams pay lower salaries than NPB clubs, making MLB contracts comparatively lucrative even at mid-tier AAV. Song earned approximately $850,000 with Kiwoom last season; his Padres deal more than triples that in year one. The KBO has seen 11 players sign MLB contracts since 2022, up from four in the prior three-year period. League officials have discussed implementing a posting system similar to Japan's, but talks stalled over revenue-sharing disagreements.
San Diego's rotation now includes Yu Darvish, Dylan Cease, Joe Musgrove, Michael King, and Song, with Matt Waldron likely shifting to long relief or a swingman role. The Padres project a $212 million luxury-tax payroll before arbitration hearings, leaving $25 million in margin before the first penalty threshold. Cease is eligible for free agency after 2025; the club has until mid-November to decide on an extension or trade. Song's club option gives San Diego flexibility if Cease walks or if prospects Jackson Merrill or Robby Snelling force earlier-than-expected promotions.
Samsung's patch talks include a clause requiring two Seoul-based promotional events annually, likely timed to the Korean baseball calendar in April and September. The Padres are discussing a return Seoul Series for 2026, pending MLB approval and venue availability at Gocheok Sky Dome. The league's international committee meets in February to allocate foreign series slots through 2028.
Song reports to spring training in Peoria on February 14. The Padres open the season March 27 in Seoul against the Dodgers.
The takeaway
Padres lock Korean pitcher for **$13M** as Samsung helmet patch talks hinge on roster presence through 2026.

Your next customer won't visit your website. Their AI will.
AI assistants have quietly taken over the first step of buying — they answer from catalogs they can read and shortlist whoever can actually ship. Two questions now decide whether you exist to that buyer: can a machine read your catalog, and can you fulfill the order. Most brands fail one or both and never find out why the orders went elsewhere. The winners of this shift aren't the loudest. They're the most readable. Build for the machine that's about to do the shopping.
