Why Infield Backup Without SS Is Surging in Popularity Among 5 Teams

Several Major League teams have shown interest in Song Sung-moon (Kium), according to a U.S. media reporter who shared the information on social media.

Jorge Castillo from ESPN, a sports media platform, stated on the 14th (Korea time) that ‘The name to watch next week is Song Seong-moon. At least five teams have shown interest. Song Seong-moon is 29 years old. He mentioned that he achieved a .315 batting average, an OPS of 0.917, and hit 26 home runs while playing for the Kiwoom Heroes in the 2025 season.’

Song Sung-moon is seeking to move to the Major League via the posting system. Song Sung-moon will be able to freely negotiate with all 30 Major League teams until 7 a.m. on the 22nd.

Major League Trade Rumors (MTR) has clearly identified the potential and constraints of Song Seong-moon.

MTR commended Song Sung-moon for not making frequent outs and possessing a strong sense of initiative, but voiced worry that he wouldn’t know until he lifted the lid.

MTR states, “The most critical issue is hitting technique. Song Sung-moon frequently swings at outside pitches. His swing paths may be susceptible to high balls. On-site evaluators see Song Seong-moon more as a utility player than a primary one. The limitation of Song Seong-moon is his shortstop defense, which plays a significant role in determining the value of a utility player.”

Nevertheless, Song Sung-moon could be a compelling option if the team requires a reserve player who can also act as a pinch-hitter at second or third base.

Kim Hye-sung of the LA Dodgers remained in the first division by serving as a substitute runner rather than a substitute batter, enabling him to cover all infield positions.

It was also claimed that the Dodgers considered Song Sung-moon as a substitute for third baseman Max Muncy. The San Francisco Giants also inquired about Song with Lee Jung-hoo, Song’s former teammate.

In the meantime, the U.S. statistical website FanGraphs projected Song’s 2026 performance using their system. Song Sung-moon was forecasted to achieve a batting average of 2551 in 145 at-bats across 36 games.
