How the analysis held up
Tampa Bay Rays won, the side LyDia's model favored.
Griffin Jax (Tampa Bay Rays), the starter LyDia's pitcher score favored, actually outpitched Jack Perkins: 5.0 IP, 0 ER (0.00 ERA) against 6.2 IP, 0 ER (0.00 ERA). The edge held up. Both starters were sharp; the edge is a narrow one between two good outings.
The Athletics bullpen was flagged as elevated risk pregame (High risk). In relief it actually allowed 1 earned run over 1.1 innings (6.75 ERA) — the risk read showed up. Note: 1 of the runs charged to the Athletics pitching staff overall was unearned — not something the bullpen's stuff should be blamed for.

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 | Athletics | Rays |
|---|---|---|
| Fatigue | 7.2/10, Tired | 5.9/10, Normal |
| Efficiency | 2.9/10, Struggling | 5.3/10, Average |
| Combined risk | 8.3/10, High risk | 5.8/10, Normal |
| Relief innings, last 7 days | 28.3 | 17.7 |
| Back-to-back arms | 4 | 7 |
| 7-day ERA | 6.35 | 4.08 |
| 7-day WHIP | 1.84 | 1.13 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
