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 | Tigers | White Sox |
|---|---|---|
| Fatigue | 6.7/10, Tired | 8.3/10, High risk |
| Efficiency | 6.8/10, Effective | 4.9/10, Average |
| Combined risk | 5.8/10, Normal | 8.4/10, High risk |
| Relief innings, last 7 days | 31.0 | 36.3 |
| Back-to-back arms | 5 | 4 |
| 7-day ERA | 2.03 | 3.96 |
| 7-day WHIP | 0.94 | 1.43 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
