U.S. Baseball Academy, San Diego

Though they operate more than 200 locations in upwards of 30 states, the team behind U.S. Baseball Academy aims to make each young athlete's experience a personal one. Their four- or six-week camps are taught by local instructors who are current or former coaches at the high school or college level, and typically offer a 6:1 or better player-to-teacher ratio for intense, professional-style training. The Academy's proven itinerary of hitting, pitching, fielding, and baserunning drills was developed by an advisory board of college coaches and Major League players, including Cy Young Award–winner and ace pitcher Brandon Webb.
