Chicago Cubs shortstop Starlin Castro maintained his innocence in the face of a sexual assault complaint, saying Friday the entire incident has taught him a valuable lesson. With Chicago police investigating a possible sexual assault last Sept. 28, Castro said he has done all he can to clear his name. Charges have not been filed. "I cooperated with the police," he said from Cubs spring training camp Friday, the first day for full-squad workouts. "... I don't have a whole lot of stuff to say about that. I'm ready to play baseball and will practice very hard to win for this team and win games." Read more: http://espn.go.com/chicago/mlb/stor...cubs-starlin-castro-says-innocent-sex-assault
