SYDNEY -- Hyun-Jin Ryu's older brother and a good friend flew to Australia to watch him pitch against the Arizona Diamondbacks on Sunday and his parents will be watching back home in Korea, where the game starts at 11 a.m.Ryu said he enjoyed Australia. He saw a koala, avoided eating kangaroo. He slept well. Sydney even has a Koreatown.Who knows, perhaps one day the Ryu family will be able to watch a game in an even more familiar setting. Major League Baseball has had discussions with South Korea about one day playing a season-opening series there.
