Sung-Mun Song

29-Year-Old Third Baseman3B
2026 Fantasy Outlook
Song is looking to follow his former Kiwoom Heroes teammates Ha-Seong Kim, Jung Hoo Lee and Hyeseong Kim this winter by making the leap to MLB. Song didn't look like a player with an MLB future until recently, recording a .690 OPS through the end of 2023, his age-26 season. Since then, he's recorded an OPS north of .900 for two straight seasons, hitting well over .300 both years while averaging 22.5 homers and 23 steals. He combines pretty good power with good contact ability as well, with a 14.3 K% over the last two seasons. Combine that with his ability to play a decent third base and you get a player who could at least get a shot at the large side of a platoon at the major-league level. Note that Lee's career MLB OPS is down 281 points from his peak KBO mark, while Ha-Seong Kim's is down 220 points from his KBO best, however. Applying the same math to Song would put his OPS somewhere between .646 and .707, which suggests he might be stuck with a bench role. Read Past Outlooks
Signed a four-year, $15 million contract with the Padres in December of 2025.
Projected for utility role

The Padres expect Song to be used in a utility role this season, AJ Cassavell of MLB.com reports.
Analysis
Inked to a four-year, $15 million contract in December, Song primarily played third base during his time with the Kiwoom Heroes of the Korea Baseball Organization. However, he also has ample experience at second and first base, and the Padres will try him out in the outfield, as well. Additionally, Song will compete with Miguel Andujar for playing time at designated hitter.

Latest Fantasy Rumors
Could see time as outfielder
3BSan Diego Padres
December 27, 2025
The Padres could use Song as an outfielder at times, according to manager Craig Stammen, per Jee-ho Yoo of the Yonhap News Agency.
Analysis
"Wherever we can get his bat in the lineup, that's what we're going to try to do. And we want to find a spot for him where he can be productive for the Padres, and there's a lot of different places that I think he can fit," Stammen told reporters. Song hasn't played in the outfield in his career, though he does possess excellent positional versatility and has bounced around the diamond while spending considerable time at first, second and third base.
