There is an amateur draft every fall. Heavily scouted teenage players often turn pro straight out of high school, a route that set Darvish and Daisuke Matsuzaka en route to the majors. Other talented players join corporate leagues or go to college to develop their games before signing with professional teams. (AP Photo/Toru Takahashi, File)
