LyDia projects 63.6% against a 56.7% no-vig market number, a 6.9% model edge at -144. Chicago Cubs owns the starting pitcher edge by 8 points. Bullpen read: Elevated volatility. Chicago Cubs's pen efficiency: Average (4.7/10). Pitching plan: Ryan Gusto 4.2 IP + remaining bullpen 4.8 IP. Bullpen fatigue, efficiency, and combined risk grade only the innings assigned to the bullpen.

Recent form supports this side and is included in the unified run projection.
Final result

How the analysis held up
Chicago Cubs won, the side LyDia's model favored.
Javier Assad (Chicago Cubs), the starter LyDia's pitcher score favored, actually outpitched Ryan Gusto: 4.2 IP, 3 ER (5.79 ERA) against 4.2 IP, 5 ER (9.64 ERA). The edge held up. Neither starter actually pitched well tonight, though — this is a smaller-of-two-bads comparison, not a starter who dealt.
The Miami Marlins bullpen was flagged as elevated risk pregame (Tired). In relief it actually allowed 1 earned run over 4.1 innings (2.08 ERA) — the risk read did not show up on the scoreboard tonight.

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 | Cubs | Marlins |
|---|---|---|
| Fatigue | 6.3/10, Tired | 6.9/10, Tired |
| Efficiency | 4.7/10, Average | 3.6/10, Below average |
| Combined risk | 6.5/10, Tired | 7.6/10, Tired |
| Relief innings, last 7 days | 25.0 | 26.0 |
| Back-to-back arms | 5 | 7 |
| 7-day ERA | 4.68 | 5.88 |
| 7-day WHIP | 1.28 | 1.58 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
