Former Los Angeles Dodgers pitcher Rick Roberts, now a coach for the University of Pittsburgh at Johnstown, Pa., gives a private lesson to Little League pitcher Andrew Watt, 11, in June. Roberts, whose big league career was cut short by ligament damage, encourages young pitchers to train properly to avoid damaging their arms. Don't throw a curveball, he tells them, until you are old enough to shave. Randy Griffith / CNHI News Service
