How the analysis held up
Chicago Cubs won, the side Leo's model favored.
Tyler Phillips (No clear pitching-plan edge), the starter Leo's pitcher score favored, actually outpitched Matthew Boyd: 4.0 IP, 0 ER (0.00 ERA) against 7.0 IP, 1 ER (1.29 ERA). The edge held up. Both starters were sharp; the edge is a narrow one between two good outings.
The Miami Marlins bullpen was flagged as elevated risk pregame (High risk). In relief it actually allowed 2 earned runs over 4.0 innings (4.50 ERA) — the risk read showed up.
The Chicago Cubs bullpen was not flagged pregame, but it had a night worth noting: 0 earned runs allowed over 2.0 relief innings (0.00 ERA) — quietly better than the pregame read implied.

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 | Marlins | Cubs |
|---|---|---|
| Fatigue | 9.0/10, High risk | 6.8/10, Tired |
| Efficiency | 4.1/10, Below average | 5.8/10, Effective |
| Combined risk | 9.5/10, High risk | 6.4/10, Tired |
| Relief innings, last 7 days | 21.7 | 20.0 |
| Back-to-back arms | 6 | 4 |
| 7-day ERA | 5.40 | 3.15 |
| 7-day WHIP | 1.43 | 1.20 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
