Miami Marlins is an official moneyline pick because it clears both gates: 73.3% model win probability and 7.2/10 Lab Rating. LyDia projects 73.3% against a 58.5% no-vig market number, a 14.8% model edge at -147. Miami Marlins owns the starting pitcher edge by 49 points. Bullpen read: Supports LyDia side. Miami Marlins's pen efficiency: Effective (5.8/10). Pitching plan: Jackson Kent 4.1 IP + remaining bullpen 4.9 IP. Bullpen fatigue, efficiency, and combined risk grade only the innings assigned to the bullpen. Lineup check: Miami Marlins is in a cold stretch (-0.056 OPS); Washington Nationals is in a cold stretch (-0.119 OPS). Recent form supports this side and is included in the unified run projection.
Final result
Marlins 2, Nationals 9
How the analysis held up
Washington Nationals won. LyDia's model favored the other side.
Eury Pérez (Miami Marlins) was LyDia's favored starter by pitcher score, but Jackson Kent actually pitched better tonight: 7.0 IP, 1 ER (1.29 ERA) against 3.0 IP, 5 ER (15.00 ERA). The edge did not show up in this game.
The Miami Marlins bullpen was flagged as elevated risk pregame (Tired). In relief it actually allowed 4 earned runs over 5.0 innings (7.20 ERA) — the risk read showed up.
The Washington Nationals bullpen was flagged as elevated risk pregame (High risk). In relief it actually allowed 1 earned run over 2.0 innings (4.50 ERA) — the risk read showed up.
Miami Marlins scored 2, 2.1 fewer than the 4.1 pregame projection.
Washington Nationals scored 9, 6.5 more than the 2.5 pregame projection.
Likely driver: Eury Pérez, the pick's own starter, was rocked for a 15.00 ERA, and Washington Nationals's offense scored 6.5 more runs than projected.

Pitching plan edge: LyDia gives Eury Pérez the edge over the Washington Nationals pitching plan (11 points on LyDia's pitcher score). Jackson Kent is projected for only 4⅔ innings, with the Washington Nationals bullpen covering the rest -- this compares Eury Pérez's own line against the Washington Nationals blended starting-pitcher-and-bullpen quality, not two starters directly.
Blended read: For the Washington Nationals, the bullpen is projected to throw more of the game than Jackson Kent (about 4⅔ innings for the starter), so LyDia grades that side on a whole-game effective ERA of 4.43 rather than Jackson Kent's own 5.68. Whole-game, that is 4.26 for the Miami Marlins against 4.43 on the other side, so the blended read leans Miami Marlins.

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 | Nationals |
|---|---|---|
| Fatigue | 8.0/10, Tired | 9.5/10, High risk |
| Efficiency | 5.8/10, Effective | 3.4/10, Below average |
| Combined risk | 7.6/10, Tired | 10.0/10, High risk |
| Relief innings, last 7 days | 25.0 | 31.7 |
| Back-to-back arms | 7 | 4 |
| 7-day ERA | 3.60 | 5.68 |
| 7-day WHIP | 1.00 | 1.77 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
