Arsenal & pitch shapes
2026 usage, velocity, and movement per pitch · dashed ring = league average for that pitch type · movement in inches, pitcher's perspective
| Pitch | Usage | Velo | vs 2025 | Velo pctl | Spin | IVB | HB |
|---|---|---|---|---|---|---|---|
| Sinker | 63.8%(+9.6) | 95.2lg 94.0 | −0.3 | 7004 | 2269 | —lg 8.4 | —lg 15.0 |
| Slider | 36.2%(−5.2) | 84.6lg 86.2 | +1.3 | 2245 | 2503 | —lg 1.5 | —lg 4.1 |
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.
No movement data for this arsenal (below the pitch-count minimum).
Mechanics Watch
2026 in gold · 2025 dashed · thin ticks = league average
Arm slot
29 pctl · +2.9° 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).
