The Map
Full interactive map →Every team on today's slate, on any two axes you pick. Pirates and White Sox are highlighted.
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 | Pirates | White Sox |
|---|---|---|
| Fatigue | 8.8/10, High risk | 8.3/10, High risk |
| Efficiency | 6.6/10, Effective | 5.2/10, Average |
| Combined risk | 8.0/10, Tired | 8.2/10, High risk |
| Relief innings, last 7 days | 29.3 | 34.7 |
| Back-to-back arms | 7 | 2 |
| 7-day ERA | 2.45 | 3.89 |
| 7-day WHIP | 0.95 | 1.30 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
