Bullpen matchup
Full Bullpen Fatigue Index →Risk is what the model actually uses: fatigue blended with how well the pen has pitched. High fatigue with high efficiency is a tired pen that is still getting outs.
| Metric | Angels | Pirates |
|---|---|---|
| Fatigue | 4.4/10, Normal | 8.7/10, High risk |
| Efficiency | 2.7/10, Struggling | 5.7/10, Effective |
| Combined risk | 5.6/10, Normal | 8.4/10, High risk |
| Relief innings, last 7 days | 17.0 | 29.7 |
| Back-to-back arms | 5 | 8 |
| 7-day ERA | 6.35 | 3.64 |
| 7-day WHIP | 1.94 | 1.08 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
