The Map
Full interactive map →Every team on today's slate, on any two axes you pick. Astros and Phillies 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 | Astros | Phillies |
|---|---|---|
| Fatigue | 6.1/10, Normal | 4.4/10, Normal |
| Efficiency | 6.7/10, Effective | 3.9/10, Below average |
| Combined risk | 5.3/10, Normal | 5.0/10, Normal |
| Relief innings, last 7 days | 19.7 | 13.0 |
| Back-to-back arms | 6 | 5 |
| 7-day ERA | 1.83 | 6.23 |
| 7-day WHIP | 1.12 | 1.23 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
