Pitch Type Abbreviations:

FB – fastball
SL – slider
CT – cutter
CB – curveball
CH – changeup
SF – split-fingered
KN – knuckleball
XX – unidentified
PO – pitch out

About split-fingered pitches: Split fingered pitches include splitters and forkballs.

About the percentages: All pitch type percentages for identified pitches are calculated as a percentage of only identifiable pitches. Unidentified pitches are calculated as a percentage of all pitches.

About the velocity: Next to the percentage in parentheses is the average velocity for the pitch type. If it reads 00.0, it means there is not enough data to calculate the average velocity.

About the leaderboards: On the leaderboards, pitch type percentage and pitch type velocity are broken out into two separate columns for each pitch. The percentage columns are labeled “%” and the velocity columns are labeled “v”.

About the data: All pitch type data is collected and provided by Baseball Info Solutions.
