BaseballAmerica.com: Prospects: Ten International Prospects To Watch In Rookie And Short-Season Ball: "5. Ji-Man Choi, c/1b, Mariners (Rookie-level Arizona League)
The Mariners drop big money in Latin America every year but they also have a strong presence in Europe and the Pacific Rim, where the Mariners went last year to sign Choi, a 19-year-old lefthanded hitter from South Korea. With quick hands and a polished bat for his age, Choi could become an offensive-oriented catcher (though he's played mostly first base temporarily), and he's shown early offensive promise in the AZL by batting .432/.511/.554 in 22 games."
Always have my eyes on South Koreans.
