Arsenal & pitch shapes
2026 usage, velocity, and movement per pitch · dashed ring = league average for that pitch type · movement in inches, pitcher's perspective

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.
Mechanics Watch
2026 in gold · 2025 dashed · thin ticks = league average
Arm slot
46 pctl · −2.2° vs prior
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).
