How the analysis held up
San Diego Padres won. LyDia's model favored the other side.
Michael King (San Diego Padres), the starter LyDia's pitcher score favored, actually outpitched Cesar Perdomo: 7.0 IP, 3 ER (3.86 ERA) against 4.2 IP, 5 ER (9.64 ERA). The edge held up.
The San Diego Padres bullpen was not flagged pregame, but it had a night worth noting: 3 earned runs allowed over 2.0 relief innings (13.50 ERA) — quietly worse than the pregame read implied.
The San Francisco Giants bullpen was flagged as elevated risk pregame (Tired). 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. Note: 1 of the runs charged to the San Francisco Giants pitching staff overall was unearned — not something the bullpen's stuff should be blamed for.
San Diego Padres scored 7, 3 more than the 4 pregame projection.
Likely driver: Cesar Perdomo, the pick's own starter, was rocked for a 9.64 ERA, and San Diego Padres's offense scored 3 more runs than projected.

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 | Padres | Giants |
|---|---|---|
| Fatigue | 7.6/10, Tired | 7.2/10, Tired |
| Efficiency | 7.2/10, Effective | 5.4/10, Average |
| Combined risk | 6.5/10, Tired | 7.0/10, Tired |
| Relief innings, last 7 days | 27.7 | 25.0 |
| Back-to-back arms | 5 | 4 |
| 7-day ERA | 1.63 | 3.24 |
| 7-day WHIP | 0.87 | 1.40 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
