How the analysis held up
Minnesota Twins won, the side Leo's model favored.
Cesar Perdomo (No clear pitching-plan edge), the starter Leo's pitcher score favored, actually outpitched Connor Prielipp: 5.1 IP, 2 ER (3.38 ERA) against 5.1 IP, 2 ER (3.38 ERA). The edge held up.
The Minnesota Twins bullpen was not flagged pregame, but it had a night worth noting: 0 earned runs allowed over 3.2 relief innings (0.00 ERA) — quietly better than the pregame read implied.
The San Francisco Giants bullpen was flagged as elevated risk pregame (Tired). In relief it actually allowed 2 earned runs over 3.2 innings (4.91 ERA) — the risk read showed up.
San Francisco Giants scored 2, 1.5 fewer than the 3.5 pregame projection.

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 | Twins | Giants |
|---|---|---|
| Fatigue | 5.7/10, Normal | 7.0/10, Tired |
| Efficiency | 5.9/10, Effective | 3.7/10, Below average |
| Combined risk | 5.3/10, Normal | 7.7/10, Tired |
| Relief innings, last 7 days | 26.0 | 22.7 |
| Back-to-back arms | 6 | 5 |
| 7-day ERA | 2.42 | 5.56 |
| 7-day WHIP | 1.38 | 1.63 |
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 above 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.
