We find ourselves in “add bats, add offense” mode this offseason and Sung-Mun Song might be a sleeper fit worth considering. The 29-year-old South Korean third baseman was recently posted for MLB free agency, giving clubs through Dec. 21 to strike a deal
He’s emerged as one of the KBO’s most dangerous left-handed hitters and isn’t just posting stats. In 2025, he slashed .315 with a career-best 26 home runs and 90+ RBIs. That kind of production, left-handed power, run production is something we can use.
Evaluating the infield mix and the need for a potent right or left-handed bat at the hot corner or perhaps first base Song offers flexibility. Though primarily a third baseman in Korea, he has experience at first and second as well. Having a lefty-power bat slot into the 3B/1B mix gives us more versatility and depth.

At 29, Song isn’t a long-term rookie project: he’s a mature hitter with a full body of work. He blossomed after returning from an earlier slow stretch, showing resilience and growth. For a club like us, one that sometimes leans heavily on upside but lacks consistency, adding a hitter like Song could balance the youth with experience and give the roster a steadier offensive anchor.
While we have focused a lot this offseason on pitching upgrades, the hitting lineup hasn’t always been reliable. A left-handed slugger who can bring both average and pop to the middle of the order could lift run production and make the lineup more dangerous. Defensively, he might not be a Gold Glove-level third baseman out of the gate but if he can provide acceptable defense, the offensive upside alone might make him worthwhile.
Signing Song isn’t a guarantee of stardom. The jump from KBO to MLB isn’t trivial. There’s always the question of whether KBO stats translate. But if he adjusts, the Angels might have landed a bargain: a proven hitter in his prime with power, average, and positional flexibility.
