And not once, but twice? I wasn't previously aware that the Korean Baseball Organization had a posting system, but apparently it works just like the one between MLB and NPB in Japan. I don't know too much about Suk-min Yoon or Hyun-Jin Ryu, but the info provided by Passan seems to indicate both are at least worth a look. EDIT: Here's an article about Yoon before a start he won 10-2 in the last WBC and some video of him.
