Many Korean baseball players have challenged overseas leagues from the past to the present. Public attention has mostly focused on those who entered American or Japanese baseball. However, some players have taken on challenges in lesser-known leagues. The topic of this article is the “third baseball leagues” outside the U.S. and Japan, specifically the Mexican League and Latin American winter leagues, as experienced by Korean players.

Korean Players in the Mexican League

The summer league commonly known as the “Mexican League” has a history of 100 years, but in Korea, it has little recognition or popularity. Even so, as many as seven Korean players have played in Mexico. The first “Mexican leaguer,” and the Korean player who spent the longest time there, was Won Kuk Lee.

Born in Seoul in 1948, Lee was a right-handed pitcher with a blazing fastball. In high school, he threw pitches close to 150 km/h (about 93 mph), drawing attention from Japanese scouts.

He moved to Japan in 1965 and joined the Tokyo Orions (now Chiba Lotte Marines) in 1966. However, he pitched in only one game in Japan. In 1968, the Orions sent him to the U.S. for training. He joined the Single-A Fresno Giants under the San Francisco Giants, later moving through the Detroit Tigers and Milwaukee Brewers farm systems, but was released in 1970.

Through a friend’s recommendation, he learned about the Mexican League and flew to Mexico in 1972. That year, with Piratas de Sabinas, he posted an 11–11 record and a 3.27 ERA. In 1973, he went 16–13 with a 2.30 ERA, showing his full potential. In 1974, he became a founding member of Mineros de Coahuila (now Acereros de Monclova) and remained a rotation starter until 1980. He wrapped up his Mexican career with Petroleros de Poza Rica in 1982 and returned to Korea in 1983 at the age of 35.

Over 10 years, he recorded 336 games, 149 wins, 128 losses, a 2.81 ERA, and 1,126 strikeouts, numbers still remembered in Mexico. In 1983, he briefly joined the KBO’s MBC Blue Dragons (now LG Twins), going 1–1 with a 4.42 ERA before retiring.

Seventeen years later, Kyung Hwan Choi (now a baseball commentator) became the first Korean hitter in the Mexican League. A left-handed outfielder, he signed with the California Angels (now Los Angeles Angels) in 1995 and played in the minors before joining Sultanes de Monterrey in 1999. He later played for Algodoneros de Unión Laguna before moving to the KBO in 2000.

At the same time in 1999, three other Koreans entered the Mexican League: Wonseong Ma (RHP, Rieleros de Aguascalientes), Sangyeong So (RHH OF, Langosteros de Cancun), and Gilnam Hong (RHP, Guerreros de Oaxaca). All were former OB Bears (now Doosan Bears) second-team players who continued short careers in Mexico after being released.

The last KBO player to challenge the Mexican League was Jinwoo Kim, a pitcher with the Kia Tigers, who appeared for Sultanes de Monterrey in 2019. In 2025, Gyeongju Kim, a Korean pitcher from an American independent team, joined Piratas de Campeche.

Korean Players in Latin American Winter Leagues

Latin American winter leagues are held from October to January in countries such as the Dominican Republic, Mexico, Venezuela, Colombia, and Puerto Rico. These short leagues are often filled with free agents hoping to reach MLB or Asian leagues, or current players seeking to maintain game sharpness during the offseason.

Korean teams generally dislike sending players abroad in winter due to concerns about injuries or fatigue. As a result, Koreans in these leagues are usually MLB or minor league players.

Only two KBO players have played in winter leagues: Youngsik Kang (LHP) and Junhyeok Heo (RHP) of the Lotte Giants, who briefly joined Leones del Escogido in the Dominican League during the 2007–08 season.

Other examples include:

• In 2009, Hyangnam Choi (RHP), then with the Triple-A Albuquerque Isotopes (LA Dodgers affiliate), pitched for Algodoneros de Guasave in the Mexican Winter League.
• Ji-man Choi (C/1B, LHB), before reaching MLB, played in two winter leagues: Tigres de Aragua in Venezuela (2014–15) and Estrellas Orientales in the Dominican Republic (2015–16).
• In 2017, two Korean MLB veterans joined Dominican teams: Jung-ho Kang (INF, Pittsburgh Pirates) with Águilas Cibaeñas, and Byung-hyun Kim (RHP, ex-MLB) with Gigantes del Cibao.

These stints were short-lived, but they represented turning points in their baseball careers abroad. They also left behind a lesson for younger players: “In baseball, there are always countless paths.”
