Sung-mun Song Posted for MLB Teams, Landing Spots, Scouting Report for KBO Slugger

Infielder Sung-mun Song, who has dominated South Korea's KBO League, has been posted for MLB teams. He is available to be signed from Saturday, Nov. 22 to Sunday, Dec. 21.

Jeeho Yoo of Yonhap News Agency shared the news on the 29-year-old Song, who hit .315 with a career-high 26 homers and 90 RBI last season.

He mainly plays third base, which could certainly make him attractive to teams needing help at a key infield position. Yoo also stated that Song can play second and that he hits left-handed and throws right-handed.

Song dominated the last two seasons. He notably hit .340 (.927 OPS) with 19 home runs and 104 RBI in 2024. Song hadn't hit higher than .263 or posted an OPS more than .691 in his previous four seasons before 2024.

Anthony Franco of MLB Trade Rumors provided a look at potentially interested teams.

"The Angels need a third baseman and are looking for a left-handed bat to balance a righty-heavy lineup. The Astros also want to bring in a lefty-hitting infielder, though they'd need to feel comfortable playing Song regularly at second base unless they trade one of Isaac Paredes or Christian Walker. The A's are in the second and third base markets, while the Mariners could be as well depending on whether they re-sign their own free agents. The White Sox, Pirates, Marlins, Rangers, Diamondbacks, Tigers and Royals (with Maikel Garcia capable of playing second) could all be in the mix for a third baseman."

Will Sammon and Cody Stavenhagen of The Athletic gave a brief look at Song.

"A late-blooming KBO infielder, Song is a versatile defender who has greatly improved his plate production over the past two seasons. He is already 29 and considered a level below a KBO comp like Ha-Seong Kim. In other words, evaluators see him as more of a utility type than an everyday player."

Eric Longenhagen of FanGraphs gave a full scouting report on Song and provided a grade of 45 (low-end regular/platoon player).

"He's been platoon neutral up to this point and has remained productive against the limited exposure to premium velocity the KBO has offered him. But his chase rate spiked to around 30% last year per Synergy, even in an environment where the average heater Song is seeing clocks in around 91 mph, and his aggressive lefty scoop of a swing is accordingly vulnerable to velocity up and away, creating substantially more hit tool risk than a .327 batting average over the last two years might indicate.

"With his defense, baserunning, and devotion to accessing his plus raw pop, Song seems better insulated from busting than some more accomplished and toolsier Pacific Rim hitters coming stateside, even if a .230 batting average feels far more likely than .330 reprise."

Three current MLB players have played in the KBO: Atlanta Braves infielder Ha-seong Kim, Los Angeles Dodgers utility player Hye-seong Kim and San Francisco Giants outfielder Jung Hoo Lee.

Song appears likely to make it four. The question is when he signs with a team and for whom.
