Managing pitcher workload is critical for both performance and injury prevention. Modern analytics tracks multiple fatigue indicators.
Key Metrics
- Pitch Count: Single-game workload limit
- Days Rest: Recovery time between starts
- Innings Limit: Season-long workload cap
- High-Stress Pitches: Pitches with high leverage
Research Findings
| Pitch Count | Velocity Drop | Next Start ERA |
|---|---|---|
| <80 | -0.3 mph | 3.80 |

| 100-115 | -1.2 mph | 4.35 |
| >115 | -1.8 mph | 4.75 |
