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 | Guardians | Rays |
|---|---|---|
| Fatigue | 10.0/10, High risk | 6.3/10, Tired |
| Efficiency | 6.0/10, Effective | 4.8/10, Average |
| Combined risk | 9.5/10, High risk | 6.4/10, Tired |
| Relief innings, last 7 days | 30.0 | 15.7 |
| Back-to-back arms | 4 | 4 |
| 7-day ERA | 3.00 | 4.60 |
| 7-day WHIP | 1.13 | 1.28 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
