Take advantage of spin axis to defy physics! Rapsodo measures the impact of spin on every ball; it shows the actual flight of a pitched baseball and calculates the corresponding trajectory of the same pitch without any spin.
How fast a pitch is traveling during flight, measured in miles per hour (MPH).
The rate at which the ball spins during flight, measured in rotations per minute (RPM). There is a stronger correlation between spin rate and swinging-strike percentage than between velocity and swinging-strike percentage.
The spin directly impacting the movement of a pitch. Also known as “useful spin,” it is perpendicular to the direction the ball is traveling, deflecting the otherwise straight horizontal and vertical path of the ball.
The tilt or angle of the baseball from the release point, measured in degrees, created by the Magnus effect. The Magnus Effect is created by the air pressure surrounding the spinning baseball on its path to home plate.

The percentage of spin directly impacting the movement of a pitch. Spin Efficiency is the ratio of true spin to total spin.
How much a ball has moved when it crosses the strike zone compared to what its position would have been without spin. Break is measured horizontally and vertically in inches.
The ballflight is show in two trajectories. A dotted line represents what the pitch would have done without spin and the solid line represents the actual movement of the pitch
The height of the ball at the point of release
The distance away from the center of the rubber from the left (-) or the right (+)
The distance away from the front of the rubber the ball was released
The vertical angle at which the ball was released out of the hand
The horizontal angle the ball was released out of the hand from the left (-) or the right (+)
“It is one thing to have a piece of equipment that functions as advertised … but it’s another thing entirely to have front-line customer service, technical support, and a tight feedback loop with experts in the industry to create an outstanding experience. Rapsodo manages to do both, which is a rare feat indeed in the baseball industry’’
“Everyone involved with teaching pitchers this day and age could benefit from owning the
Rapsodo device and using it for immediate
feedback to educate their pitchers’’
