IVB = induced vertical break (rise vs gravity-only). HB = horizontal break. Velo percentile is against all pitchers throwing the same pitch type. Sources: Savant pitch arsenals & movement leaderboards.

What this can't see: Joint kinetics, hip-shoulder separation, and kinematic sequencing (Hawkeye/KinaTrax, team-internal — never estimated here). Stance angle and foot separation (Savant visuals only, no export). Release extension (column exported empty; needs pitch-level ingest).
