How the analysis held up
Washington Nationals won, the side LyDia's model favored.
Cade Cavalli (Washington Nationals), the starter LyDia's pitcher score favored, actually outpitched Sandy Alcantara: 4.0 IP, 0 ER (0.00 ERA) against 6.0 IP, 4 ER (6.00 ERA). The edge held up.
The Miami Marlins bullpen was flagged as elevated risk pregame (Tired). In relief it actually allowed 0 earned runs over 3.2 innings (0.00 ERA) — the risk read did not show up on the scoreboard tonight. Note: 1 of the runs charged to the Miami Marlins pitching staff overall was unearned — not something the bullpen's stuff should be blamed for.
The Washington Nationals bullpen was flagged as elevated risk pregame (High risk). In relief it actually allowed 4 earned runs over 6.0 innings (6.00 ERA) — the risk read showed up.

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 | 7.8/10, Tired | 7.6/10, Tired |
| Efficiency | 5.4/10, Average | 3.6/10, Below average |
| Combined risk | 7.6/10, Tired | 8.3/10, High risk |
| Relief innings, last 7 days | 25.0 | 28.3 |
| Back-to-back arms | 7 | 4 |
| 7-day ERA | 4.32 | 5.72 |
| 7-day WHIP | 1.00 | 1.66 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
