South Korean pitcher Ko Woo‑seok joins Minnesota Twins roster

South Korean reliever Ko Woo‑seok was acquired by the Minnesota Twins in a cash trade from the Detroit Tigers. The deal includes an assignment clause that guarantees his placement on the Twins’ 26‑man major‑league roster, making him the 30th Korean player to reach the MLB level. He is slated to be added to the roster ahead of the Twins’ home game against the Cleveland Guardians.

Ko, who previously served as a closer for the KBO’s LG Twins, signed with the San Diego Padres via the posting system in late 2023 but did not break into the majors. He then spent time with the Miami Marlins organization before joining Detroit’s Triple‑A affiliate, the Toledo Mud Hens, where he posted a 2.60 ERA and a 29.1% strike‑out rate over 27⅔ innings without allowing a home run. The Twins, whose bullpen currently ranks near the bottom of the league with a 5.28 team ERA, see Ko’s strikeout ability and low home‑run rate as a boost for their struggling relief corps.
