How the analysis held up
Miami Marlins won, the side LyDia's model favored.
LyDia's two internal reads disagreed pregame by 40 points — the team-strength model favored Miami Marlins, the run-projection model favored Kansas City Royals. The team-strength model had the winner here.
Eury Pérez (Miami Marlins) was LyDia's favored starter by pitcher score, but Noah Cameron actually pitched better tonight: 5.0 IP, 4 ER (7.20 ERA) against 4.2 IP, 6 ER (11.57 ERA). The edge did not show up in this game. Both starters struggled; this was not a case of one clean outing beating one bad one.
The Miami Marlins bullpen was flagged as elevated risk pregame (Tired). In relief it actually allowed 0 earned runs over 4.1 innings (0.00 ERA) — the risk read did not show up on the scoreboard tonight.
The Kansas City Royals bullpen was not flagged pregame, but it had a night worth noting: 4 earned runs allowed over 4.0 relief innings (9.00 ERA) — quietly worse than the pregame read implied. Note: 1 of the runs charged to the Kansas City Royals pitching staff overall was unearned — not something the bullpen's stuff should be blamed for.
Miami Marlins scored 9, 6.2 more than the 2.8 pregame projection.
Kansas City Royals scored 6, 1.5 more than the 4.5 pregame projection.

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 | Royals |
|---|---|---|
| Fatigue | 7.4/10, Tired | 5.1/10, Normal |
| Efficiency | 4.7/10, Average | 7.5/10, Dominant |
| Combined risk | 7.6/10, Tired | 3.9/10, Normal |
| Relief innings, last 7 days | 24.0 | 19.0 |
| Back-to-back arms | 7 | 4 |
| 7-day ERA | 4.88 | 1.42 |
| 7-day WHIP | 1.21 | 0.74 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
