How the analysis held up
Miami Marlins won. LyDia's model favored the other side.
Jackson Kent (Washington Nationals) was LyDia's favored starter by pitcher score, but Janson Junk actually pitched better tonight: 4.2 IP, 1 ER (1.93 ERA) against 4.2 IP, 3 ER (5.79 ERA). The edge did not show up in this game.
The Washington Nationals bullpen was not flagged pregame, but it had a night worth noting: 3 earned runs allowed over 3.1 relief innings (8.10 ERA) — quietly worse than the pregame read implied.
The Miami Marlins bullpen was flagged as elevated risk pregame (High risk). 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.
Miami Marlins scored 6, 3.8 more than the 2.2 pregame projection.
Likely driver: Jackson Kent, the pick's own starter, was rocked for a 5.79 ERA, and the Washington Nationals bullpen allowed 3 earned runs over 3.1 relief innings (8.10 ERA), which was not flagged pregame but showed up anyway.

Pitching plan edge: LyDia gives the Washington Nationals pitching plan the edge over Janson Junk (7 points on LyDia's pitcher score). Jackson Kent is projected for only 4 innings, with the Washington Nationals bullpen covering the rest -- this compares the Washington Nationals blended starting-pitcher-and-bullpen quality against Janson Junk's own line, not two starters directly.
Blended read: For the Washington Nationals, the bullpen is projected to throw more of the game than Jackson Kent (about 4 innings for the starter), so LyDia grades that side on a whole-game effective ERA of 4.01 rather than Jackson Kent's own 8.03. Whole-game, that is 4.01 for the Washington Nationals against 4.31 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 | 6.8/10, Tired | 8.6/10, High risk |
| Efficiency | 6.6/10, Effective | 4.7/10, Average |
| Combined risk | 6.0/10, Normal | 8.8/10, High risk |
| Relief innings, last 7 days | 19.7 | 25.0 |
| Back-to-back arms | 4 | 6 |
| 7-day ERA | 1.83 | 4.68 |
| 7-day WHIP | 1.17 | 1.28 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
