How the analysis held up
Houston Astros won, the side LyDia's model favored.
Hunter Brown (Houston Astros), the starter LyDia's pitcher score favored, actually outpitched Luis Castillo: 6.0 IP, 2 ER (3.00 ERA) against 4.0 IP, 6 ER (13.50 ERA). The edge held up.
The Chicago White Sox bullpen was not flagged pregame, but it had a night worth noting: 0 earned runs allowed over 4.0 relief innings (0.00 ERA) — quietly better than the pregame read implied.
The Houston Astros bullpen was not flagged pregame, but it had a night worth noting: 0 earned runs allowed over 3.0 relief innings (0.00 ERA) — quietly better than the pregame read implied.

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 | White Sox | Astros |
|---|---|---|
| Fatigue | 5.9/10, Normal | 6.7/10, Tired |
| Efficiency | 6.1/10, Effective | 5.4/10, Average |
| Combined risk | 5.4/10, Normal | 6.5/10, Tired |
| Relief innings, last 7 days | 26.0 | 29.7 |
| Back-to-back arms | 3 | 5 |
| 7-day ERA | 2.77 | 3.64 |
| 7-day WHIP | 1.12 | 1.28 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
