The Twins signed Plutko to a minor-league contract Friday.
Plutko, 32, is coming off a terrific two-year stint in the Korea Baseball Organization, having collected a 2.40 ERA and 250:69 K:BB over 285.1 innings with the LG Twins. He's posted a 5.39 ERA across 88 appearances in parts of five major-league seasons, which kept him from getting a big-league contract even after his successful stint overseas. Plutko will head to Triple-A St. Paul.
