MIAMI GARDENS, Fla. – Sometime last week, Jayson Werth received a text message from his agent, Scott Boras, that unlocked something for him. It was a simple message, because baseball, once you strip away the television cameras and empty clichés and white noise, is a simple game. The message read: “The key is get on base and use your speed.” “It was kind of an enlightening moment,” Werth said Saturday afternoon, sipping a cup of coffee at his locker.
