The Chicago Police Department is expecting to talk to Cubs shortstop Starlin Castro about a sexual assault accusation when the All-Star is in town for this weekend's fan convention, according to a source. A woman accused Castro of sexual assault last fall, but no charges have been filed and Castro's representatives deny the allegation. "I don't think it's the right time or forum to talk about that," Cubs president of baseball operations Theo Epstein said Wednesday. "As facts develop and the story evolves, there will be an appropriate time to talk about that."
