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 | Athletics | Mariners |
|---|---|---|
| Fatigue | 8.7/10, High risk | 6.0/10, Normal |
| Efficiency | 5.4/10, Average | 3.2/10, Below average |
| Combined risk | 8.5/10, High risk | 6.9/10, Tired |
| Relief innings, last 7 days | 31.0 | 25.3 |
| Back-to-back arms | 5 | 5 |
| 7-day ERA | 3.48 | 6.39 |
| 7-day WHIP | 1.32 | 1.62 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
