In the recent study, it was revealed that the throw trajectory is changed by speed, number of revolutions, rotation axis degree, the seam shape of the ball surface. We carried out the pitching experiment to the clarify the influence of the angle of inclination to the trajectory of the ball. The pitching test was carried out by 12 pitchers of the baseball club in the university. The IoT ball is used to measure speed, number of revolutions and angle of inclination. The trajectory of the ball measured it using a high-speed camera. The simulation performed the comparison with the serial photographs of high-speed camera. As a result, the throw trajectory changes laterally as the rotation axis degree. In other words, it was revealed that final positions of ball were different by the angle of inclination.
