The San Diego Padres signed Korean right-hander Song Sung-mun to a $13 million contract, the organization announced Tuesday, securing the 20-year-old directly from the international market before Korea Baseball Organization clubs could extend formal offers. Song bypassed the KBO draft entirely, opting for MLB's guaranteed dollars over domestic development. The deal ranks among the top 15 international pitcher contracts signed in the past three years.
Song threw 96 mph with a vertical slider in Korean amateur showcases last autumn, according to two Pacific Rim scouts who watched him in Busan. He stands 6-foot-2, throws from a high three-quarters slot, and logged 140 innings across high school and club ball without surgery. The Padres' international scouting coordinator flew to Seoul twice in December. The Lotte Giants and Doosan Bears each prepared KBO rookie-scale offers in the ₩800 million range—roughly $560,000—before Song's agent closed negotiations.
The signing matters because San Diego now controls six Korean-born players across the organization, more than any MLB club outside the Dodgers. The Padres' Glendale complex employs two Korean-language interpreters and a Seoul-based advance scout who reports directly to general manager A.J. Preller. Song will train in Arizona before assignment to Single-A Lake Elsinore, where Ha-Seong Kim rehabbed in 2022. The internationalization isn't aesthetic. Korea's amateur exit pipeline has produced 12 All-Star selections since 2015, per Baseball Reference, and the country's broadcast rights for Padres games tripled to $4.2 million annually after Kim's 2021 signing. Sponsors care. Kia Motors inked a $9 million patch deal in 2023 contingent on Korean roster presence.
The $13 million figure splits cleanly: $5 million signing bonus, $8 million guaranteed across a four-year minor-league contract with two club options. If Song reaches the majors before 2027, the final option escalates to $2.8 million. The structure mirrors Tampa Bay's 2019 deal with Taiwanese right-hander Chih-Wei Hu, who never threw a big-league pitch but whose signing unlocked a $7 million annual media package with Taiwan's ELTA Sports. The Padres are pricing upside and off-field yield together.
Watch Song's visa processing—he needs a P-1A before April 1 to participate in spring exhibitions. The Padres' April 12 Seoul Series games against the Dodgers create jersey-sale optionality if Song appears in any capacity. Korea's Naver streamed Kim's 2021 debut to 1.8 million concurrent viewers. Also watch whether San Diego's international bonus pool resets before July's signing period; the club spent $4.9 million of its $5.7 million allotment in this window. Front-office calendar: Preller meets with Nike's Asia-Pacific team in Portland on March 3, per two people briefed on the agenda.
The Giants and Bears now pivot to Japan's industrial leagues, where unsigned 21-year-olds don't require MLB posting fees. Song's agent has three other Korean clients in showcases this spring.
