Follow UsNEW YORK — The Yankees continue to widen their search for talent in international markets. Their latest interest centers on a Korean infielder whose unexpected rise has caught the eye of evaluators across baseball.
Sung Mun Song, a 29 year old third baseman from the Kiwoom Heroes, has drawn interest from several teams. The Yankees are among six clubs now monitoring him closely. His ability to play first, second and third base makes him an intriguing offseason option.
The transformation nobody saw coming
Song spent years trying to secure a permanent role with the Heroes. He entered the KBO in 2015 as a fifth round draft pick. His development moved slowly. He remained in the minors for the full 2016 season. When he returned to the top league, he delivered modest results. From 2022 through 2023, he hit .253 with an 85 wRC+. The production suggested a utility ceiling.
His baseball path also paused because of mandatory military service. Song missed all of 2020 and part of 2021 while completing his commitment. Many believed he would top out as a role player and nothing more.
Then he arrived in 2024 and changed the narrative.
Numbers that demand attention
Song hit .340 in 2024 with 19 home runs and 21 steals. His 143 wRC+ showed elite offensive production. He became the first player in KBO history to reach more than 20 steals without getting caught once. That level of efficiency pushed him into the spotlight.
Concerns remained about whether the breakout would hold. In 2025, he proved he could sustain it. Song raised his home run total to 26 and hit .315. His wRC+ rose to 151. He stole 25 bases and earned his first All Star selection. In August, he won KBO Player of the Month after leading all hitters with 42 hits and a .726 slugging percentage. His late season surge turned him into one of the league’s most productive players.
What Yankees scouts see in him
The Yankees need more infield depth entering 2026. Song offers the kind of flexibility teams value. His defensive ability at three spots gives manager Aaron Boone options on days when injuries or matchups require adjustments.
Scouts believe Song handles high velocity better than fellow Korean infielder Hyeseong Kim. Reports say his bat to ball skills and timing on fastballs are strengths. While his defense does not measure as strongly as Kim’s, his offensive profile carries more weight for a utility role.
Song’s blend of power and speed is rare. He entered the 20 home run and 20 steal club in August with his 20th homer. That athleticism could give the Yankees something they do not currently have on the bench.
The competition heats up
Six teams have followed Song closely. The Giants, Cubs, Mariners, Angels and Pirates all sent scouts this season. Interest across both leagues suggests bidding could intensify once he becomes available.
Kiwoom signed Song to a six year extension worth 8.6 million dollars in August. The contract includes language allowing him to request posting. He confirmed those intentions during an interview with Jee-ho Yoo of Yonhap News Agency. Song will ask the Heroes to post him after the season.
Mark Pieper of ISE Baseball, Song’s agent, said his client wants to move to MLB. The Heroes support the decision even after signing him long term. Their willingness gives Song an open path to pursue his goal of playing in the United States.
The posting process explained
If the Heroes post Song, he will enter a 30 day negotiation window. All 30 MLB teams can contact him during that period. Any signing club must pay Kiwoom a posting fee. That fee equals 20 percent of the first 25 million dollars in the contract, 17.5 percent of the next 25 million dollars and 15 percent of anything above that amount.
If an agreement does not happen within the deadline, Song can return to the Heroes. His extension gives the team financial stability while allowing him to chase an MLB opportunity.
A crowded international market
Song joins a busy international class. Japanese star Munetaka Murakami highlights the group and is expected to draw heavy interest. The Yankees have also shown interest in Japanese pitcher Tatsuya Imai. Korean first baseman Baek-Ho Kang plans to enter MLB free agency in 2026.
The wide range of available talent gives teams different options. Song sits in the middle tier. He is not expected to command the large deal that Murakami will receive. But he offers more versatility than many players in his position group. His later career breakout brings some risk. Yet his back to back elite seasons indicate he may have found sustainable changes in his approach.
The Yankees’ international strategy
The Yankees have expanded their international search in recent years. Their front office believes the global market provides value opportunities. Song fits their approach as a player with strong recent performance and versatility.
His ability to move across the infield is valuable for a roster that often adjusts due to injuries. His right handed bat also differs from most of the current bench profiles. Yankees decision makers want players who can contribute without limiting roster flexibility.
The Yankees face questions about their infield depth. They want players who can cover multiple positions while still offering production. Song meets those needs and does so without requiring a large financial investment.
What happens next
The KBO season ended recently. Song is expected to file his posting request soon. Once he does, MLB teams will decide how aggressively they want to pursue him.
Song expressed confidence in his readiness for MLB competition. Players who show that mindset often adapt better because they understand the challenge. The Yankees must decide if his improvement is real. Two strong seasons suggest growth rather than luck. His speed, instincts and contact skills were always present. In 2024 and 2025, he matched those traits with power.
If the Yankees believe his rise is genuine, Song could become a smart offseason addition. He gives depth without blocking prospects. He also fits the organization’s push to find impact players overseas. For a Yankees team trying to strengthen its roster through every possible avenue, Song stands out as a player worth serious consideration.
