Cubs shortstop Starlin Castro met with the media on Friday but declined to talk about the claim by a woman that he sexually assaulted her in his apartment in September. Castro met with Chicago police in January. No charges have been filed against him, and his representatives have insisted he is innocent. "I cooperated with the police and talking about that," he said. "I don't have (anything) to say about that. I'm ready to play baseball and am practicing very hard." Asked what lessons he learned, Castro replied: "That you've got to be careful because there are a lot of bad people in the world." Not to trust everyone? "Yeah, something, like that," he said. Castro has not spoken to the media since reports surfaced in January about the incident. He said he's trying to concentrate on his job and focus on the future. "In the beginning it was tough," he said. "I've taken this out of my mind and am preparing to play baseball." Cubs Chairman Tom Ricketts also declined to comment on Castro's situation. "Obviously we're glad Starlin is here," he said. "Beyond that, it's really him and his advisors that you should ask about his situation." Ricketts insisted he doesn't "know any specifics about the situation," adding "the fact is we want all of our guys to behave themselves off the field."
