Byung-Hyun Kim (born January 21, 1979 in Gwangju, South Korea) is a right-handed pitcher who has played for the Colorado Rockies since 2005. Previously, he played for the Arizona Diamondbacks (1999-2003), the Boston Red Sox (2003-2004), and for the Colorado Rockies (2005-present).
Usually described as a submarine pitcher, Kim is a side-arm and under-arm hard thrower who uses a great variety of deliveries. Kim possesses a 90-MPH fastball, a decent curve, a slider, a sinker, a two-seam fastball, and a changeup which he uses to freeze opposing hitters. Nevertheless, his main problem has been a lack of concentration and an inability to handle pressure. He struggles against left-handed batters.
Named both the Most Valuable Player and Most Valuable Pitcher for the National High School championships in Korea, Kim was selected to the 1996 National Junior Team, then named to the National Team in both 1997 and 1998. In that year, he manhandled the US Olympic team, striking out 15 batters in 6 2/3 innings. Later, he helped Korea claim the gold medal in the Asian Games held in Bangkok, Thailand.
