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 | Mariners | Blue Jays |
|---|---|---|
| Fatigue | 6.2/10, Tired | 9.9/10, High risk |
| Efficiency | 3.5/10, Below average | 4.0/10, Below average |
| Combined risk | 7.0/10, Tired | 10.0/10, High risk |
| Relief innings, last 7 days | 22.7 | 31.3 |
| Back-to-back arms | 5 | 6 |
| 7-day ERA | 6.35 | 5.17 |
| 7-day WHIP | 1.46 | 1.56 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
Run total projection
Full Totals Projections →The model projects 1.5 runs below the market total. A research lean still requires a setup rating of at least 7.0/10. Team totals remain research-only until their graded sample is established.
