Foreigners in the KBO
From the Korea Times, an articles about foreign players in Korea. Just a little background, the title of the article is "the mercenaries," which is the translation of the Korean word '용병.' Foreigner players are commonly called this in Korean. The official expression is 외국인 선수, which simply means foreign player.
An article from the JoongAng Daily about foreign players, especially foreign pitchers (as these days, most of them are pitchers).
