Pitch classifications provided by the Gameday Algorithm and may be inaccurate.
Clicking individual pitch types will provide individual velocity histograms for each pitch.

Nibbleness is the arithmetic mean of the distance of each pitch, in inches, from the edge of a normalized strikezone. Lower indicates "more Nibbley".
Time to Plate is the time, in seconds, that it takes an average pitch of this type to reach the plate. This is strongly correlated with velocity, but also factors in movement.
