Understanding Slurve: Average Spin

How fast the ball spins, measured in turns per minute. Only measured pitches are included. More spin is not always better. Uses pitches recorded as slurve.

Formula: Sum of recorded spin rates ÷ pitches with spin measurements

Read rates alongside playing time. A small sample can produce an extreme result, and a missing value is different from zero.

Season rankings use regular-season records. A player has one combined row across teams; the team label identifies the associated team, not a separate team stint.
