GLENDALE, Ariz. -- As the only Dodgers player who will actually be closer to his home when the team opens its season in Australia in a few weeks, Hyun-Jin Ryu offered some advice about adjusting to such a flar-flung time zone."The best thing to do is not to sleep during the day. No naps," Ryu said through a translater. "There's no secret formula."Ryu might need to heed his own advice, because after Zack Greinke left his first spring start with a strained right calf Thursday, Ryu's chances of pitching at the Sydney Cricket Ground against the Arizona Diamondbacks increased considerably.
