The maximum observed fastball velocity in the given event year. Measured in miles per hour (MPH).

The average velocity for all pitches of this type in the given event year. Measured in miles per hour (MPH).

The average rate of spin for all pitches of this type in the given event year. Measured in rotations per minute (RPM).

The average spin efficiency for all pitches of this type in the given event year. Displayed as a percent (%).

The average Bauer Units value of all fastballs in the given event year. Bauer Units are calculated for each pitch by dividing Spin Rate by Velocity.

The average total non-gravity movement for all pitches of this type in the given event year. Measured in inches (in).

The average velocity for all pitches of this type in the given event year. Measured in miles per hour (MPH).

The average rate of spin for all pitches of this type in the given event year. Measured in rotations per minute (RPM).

The average total non-gravity movement for all pitches of this type in the given event year. Measured in inches (in).

The average velocity for all pitches of this type in the given event year. Measured in miles per hour (MPH).

The average rate of spin for all pitches of this type in the given event year. Measured in rotations per minute (RPM).

The average total non-gravity movement for all pitches of this type in the given event year. Measured in inches (in).

A fastball with hop has a flat approach angle and visually jumps through the zone. When thrown up in the zone, it is more likely to generate a higher swing and miss average. Hop+ of 100 is MLB average.

A fastball with sink has low backspin and drops through the strike zone. When thrown down in the zone, it is more likely to generate a higher ground ball percentage and lower launch angle. Sink+ of 100 is MLB average.

A fastball with rise has a high percentage of backspin. When thrown up in the zone, it is more likely to generate a higher fly ball percentage. Rise+ of 100 is MLB average
