Four-seam fastball: Average Spin 2023

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 four-seam fastball.

Season

At least 100 pitches of this type with a spin measurement in this season. Recorded pitch types. Usage divides by all delivered pitches, including unknown types. Speed is in mph, spin in rpm and extension in feet. Averages use measured pitches only. Whiffs divide misses by swings. Data through December 31, 2023. Data refreshed Sep 9, 2026, 10:27 AM UTC.

FF rpm: 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 four-seam fastball.

Understanding Four-seam fastball: 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 four-seam fastball.

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.
