The San Diego Padres have a new infielder.
Sung-mun Song has signed with the Padres on Friday, according to ESPN's Jorge Castillo.
Song, mostly a third baseman, may have to move elsewhere in San Diego. But that's something to worry about once spring gets here.
For now, the big deal is that the Padres landed a quality free agent, and their team will be better for it.
Here's what to know about Song.
Who is Sung-mun Song?
Song is a 29-year old Korean infielder.
He throws right-handed but bats left-handed, and he'll turn 30 in August.
He played for the Kiwoom Heroes in the Korea Baseball Organization. Song signed a six-year extension in August 2025, but he quickly asked to be posted after the season, and now he's coming to MLB.
