Washington Nationals remains on the watchlist. Lab Rating 6.8/10: conviction 20, pitching plan 17, bullpen 13.11, offense 18.03. LyDia projects 73.2% against a 37.6% no-vig market number, a 35.6% model edge at +158. Washington Nationals owns the starting pitcher edge by 17 points. Bullpen read: Elevated volatility. Washington Nationals's pen efficiency: Effective (5.5/10). Pitching plan: Brad Lord 1.9 IP + remaining bullpen 7.1 IP; Ryan Gusto 4.0 IP + remaining bullpen 5.0 IP. Bullpen fatigue, efficiency, and combined risk grade only the innings assigned to the bullpen. Lineup check: Washington Nationals is in a cold stretch (-0.061 OPS); Miami Marlins is near its season form (+0.004 OPS). Recent form leans against this side and is included in the unified run projection.

Pitching plan edge: LyDia gives the Washington Nationals pitching plan the edge over Ryan Gusto (17 points on LyDia's pitcher score). Brad Lord is projected for only 2 innings, with the Washington Nationals bullpen covering the rest -- this compares the Washington Nationals blended starting-pitcher-and-bullpen quality against Ryan Gusto's own line, not two starters directly.
Blended read: For the Washington Nationals, the bullpen is projected to throw more of the game than Brad Lord (about 2 innings for the starter), so LyDia grades that side on a whole-game effective ERA of 3.65 rather than Brad Lord's own 4.04. Whole-game, that is 3.65 for the Washington Nationals against 4.69 on the other side, so the blended read leans Washington Nationals.
How to read this: the scorecards above name the starters; every number lives in this table. Highlighted cells mark a gap big enough to matter. K% and BB% are strikeout and walk rate as a share of batters faced -- K-BB% is the two combined into one skill number. HR/9 is home runs allowed per nine innings. Ground-ball and fly-ball rate are neither good nor bad on their own: high ground-ball pitchers trade strikeouts for double plays and fewer home runs, and on this data source the two rates are complementary (they add to 100%), not independent reads.

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 | Nationals | Marlins |
|---|---|---|
| Fatigue | 5.2/10, Normal | 6.1/10, Normal |
| Efficiency | 5.5/10, Effective | 4.5/10, Average |
| Combined risk | 5.0/10, Normal | 6.4/10, Tired |
| Relief innings, last 7 days | 23.0 | 21.3 |
| Back-to-back arms | 3 | 4 |
| 7-day ERA | 3.13 | 4.64 |
| 7-day WHIP | 1.39 | 1.45 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
