The purpose of this study was to describe the three-dimensional kinematics of batted baseballs toward the same-field, center-field, and opposite-field, and estimate the effect of ball spin on trajectory and flight distance. Two collegiate baseball players performed free-batting, and they were instructed to hit a ball as far as possible in each direction. Twenty-seven trials were analyzed, and compared the ball kinematics among three hitting directions. The mean flight distance for the center-field was greater than that of the other fields. For the same-field and opposite-field, the amount of side spin components was larger than that of the center-field. Thus, it was indicated that the batted ball trajectories for the same-field and opposite-field were curved due to the Magnus force works horizontally, and flight distance tended to be shorter than that of the center-field.
