Biographical Information[edit]
Sung-mun Song played in the Korea Baseball Organization from 2015 to 2025, then requested to be posted in order to play in Major League Baseball.
Song was drafted by the Nexen Heroes in the 5th round of the 2015 KBO draft, and he went 3-for-12 in 2015, his first season. He was placed in the minors for the entire 2016 season, and he hit .273/.360/.338 in 2017. Song improved to .313/.381/.502 with 7 homers in 2018, but he slumped to .227/.269/.328 in 2019. In the 2019 Korean Series, he was 6-for-12 with a clutch game-tying RBI single in Game 1, but the Heroes were still swept by the Doosan Bears. He missed the next two seasons due to military service, and he played 66 games with a .249/.320/.371 batting line in 2021 after returning.
The Seoul native only hit .247/.302/.371 in 2022, but he shined in the postseason again. He was 8-for-21 in the 2023 Korean Series, though the Heroes lost again in 6 games, this time to the SSG Landers. Song recorded a .263/.325/.358 batting line in 2023, and he broke out in 2024. He was selected into the 2024 KBO All-Star Game, and he went 0-for-1 with a walk against Won-jung Kim. He ended up hitting .340/.409/.518 with 19 homers and 21 steals, and he was the first player to steal more than 20 bases without being caught in KBO history. Song ranked 5th in batting (between Ja-wook Koo) and Chang-ki Hong) and 5th in hits (between Mel Rojas Jr. and Hong). He made it onto Korea's roster for the 2024 Premier 12. He was 2 for 13 with two walks, a steal, a run and a RBI, backing up at 1B, 2B and 3B and fielding .962.
In 2025, he produced at a .315/.387/.530 rate with 103 runs, 37 doubles, 26 homers, 90 RBI and 25 steals in 27 tries, fielding .959 at the hot corner. He was second in runs (3 behind Koo), 7th in average (between Koo and Lewin Díaz), second in hits (181, 6 behind Víctor Reyes), 3rd in doubles (after Koo and Reyes), 6th in homers, tied Hyun-soo Kim for 8th in RBI, missed the top-10 in steals by one, tied Hae-min Park for 8th in walks (68), 9th in OBP (between Austin Dean and Reyes), 6th in slugging (between Eui-ji Yang and Hyoung-woo Choi) and 7th in OPS (between Koo and Seong-yoon Kim). He was placed on the posting system in order to join MLB on November 22nd. That made him the fifth player to be posted that off-season, joining four players from Nippon Pro Baseball, which was the most in any one year since the creation of the system. On December 19th, he came to an agreement with the San Diego Padres.
He started the 2026 season in the minors, playing for the El Paso Chihuahuas of the Pacific Coast League. He was batting .293 after 20 games when he was called up to San Diego on April 25th as one of a couple extra players available for their week-end series against the Arizona Diamondbacks played in Mexico City. He made his debut in the second game the next day, serving as a pinch-runner for catcher Luis Campusano in the 8th inning. He was then sent back to El Paso after the game.
