LOS ANGELES -- If you're wondering how Hyun-Jin Ryu will pitch under the pressure of his first postseason, consider that in 2008, he pitched a 1-0 shutout over Canada to help the South Koreans win the Olympic gold medal in Beijing. By doing so, Ryu got out of two years' military service."That's very important to them, because in two seasons they can make a lot of money," said Korean reporter Junki Hong of the daily newspaper Chosun Ilbo.
