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 | Cubs | Brewers |
|---|---|---|
| Fatigue | 4.8/10, Normal | 8.8/10, High risk |
| Efficiency | 3.8/10, Below average | 5.5/10, Effective |
| Combined risk | 5.4/10, Normal | 8.6/10, High risk |
| Relief innings, last 7 days | 23.0 | 28.7 |
| Back-to-back arms | 4 | 6 |
| 7-day ERA | 5.48 | 3.45 |
| 7-day WHIP | 1.61 | 1.29 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
