The greatest star of Korean professional baseball, Choi Dong-won of Yonsei University passed away due to illness. With the death of Choi, Korean baseball lost another big star after the recent death of Jang Hyo-jo of Samsung Lions. Choi Dong-won, who was the Hanwha Eagles coach and formerly played in Lotte Giants after graduating from Kyungnam High School and Yonsei University, passed away. It has been told that his condition had recently worsened significantly and that he was hospitalized at Ilsan Hospital. Choi was diagnosed with colorectal cancer in 2007 when he was in the Hanwha Eagles as a coach. He was a member of the KBO in 2009 when his condition improved for a while. However, he recently stayed in Pocheon, Gyeonggido as his condition deteriorated since last year. Last July, Choi shocked baseball fans with his scrawny figure when he made a public appearance as representative of Kyungnam High School at the “Legend Match” between Kyungnam High School and Gunsan High School. At the time, Choi did not let the fans know of his illness by explaining, "I went on a diet after gaining too much weight, but now I lost too much.” Choi’s younger brother and KBO referee Choi Su-won said, “Even though he was mostly unconscious, he showed enormous strength whenever he was awake, comforting his family that things will be okay, but he wasn’t able to overcome the cancer in the end.” In 1984 during the Korean Series, Choi, whose gold-rimmed eyeglasses and over-150km fastballs were trademarks, scored “four single-handed victories” against Samsung. This record is unprecedented until today and is when Choi got his nickname “iron arm.” In 1975, Choi who was a sophomore at Kyungnam High School showed potential early on when he scored a no-hit no-run against Kyungpook High School which was known as being the very best at the time. In the following year, he scored 20 strike-outs during a game against Gunsan Commercial High School. In 1981, he entered Lotte and won numerous awards including MVP and became the greatest player. He became part of the professional baseball league in Lotte in 1983 and made history in 1984 when he was chosen as MVP with an unbelievable record of 27 wins 13 losses and 6 saves. With this, Lotte became part of the Korean Series and it was during this series that Choi became the “iron arm” with the “four single-handed victories.” In total, Choi held a record of 103 wins 74 losses and 26 saves, with an earned run average of 2.46. Out of 248 pro games, he pitched the full nine innings for 80 of them, and did not allow any points to the opponent team during 15 of those games.
