Miley (neck) will throw a live batting practice session Sunday, Jordan Bastian of MLB.com reports.
Miley ended last season on the injured list with a strained neck, though his delayed start to camp is supposedly due to the Cubs' program for handling veteran pitchers and not due to that injury. He won't be able to throw many Cactus League innings prior to Opening Day, however, so it's possible Miley will be on a pitch count for his first start or two of the regular season.
