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 | Marlins | Nationals |
|---|---|---|
| Fatigue | 7.1/10, Tired | 8.0/10, Tired |
| Efficiency | 5.1/10, Average | 3.3/10, Below average |
| Combined risk | 7.1/10, Tired | 8.9/10, High risk |
| Relief innings, last 7 days | 24.7 | 32.3 |
| Back-to-back arms | 7 | 4 |
| 7-day ERA | 4.38 | 6.12 |
| 7-day WHIP | 1.14 | 1.67 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
