Description
Wrist height at release measures the vertical position of the wrist at the instant of ball release, relative to the rear toe height at the start of the pitch (used as a proxy for mound level).Normative Ranges
Percentile distributions by competition level from the 2026 Q1 dataset; the optimal range spans the 75th–90th percentiles.| Population | Optimal Range (75th–90th) | 10th | 25th | 50th | 75th | 90th |
|---|---|---|---|---|---|---|
| Youth | 39.6 – 43.5 in | 31.5 | 33.9 | 37.3 | 39.6 | 43.5 |
| High School | 44.9 – 47.8 in | 35.0 | 38.9 | 42.5 | 44.9 | 47.8 |
| College | 47.1 – 53.1 in | 34.6 | 37.8 | 42.0 | 47.1 | 53.1 |
| Professional | 58.1 – 75.0 in | 40.6 | 44.4 | 50.4 | 58.1 | 75.0 |
| Broad (All Levels) | 45.8 – 52.6 in | 33.0 | 37.1 | 41.1 | 45.8 | 52.6 |
