How the analysis held up
Chicago White Sox won, the side LyDia's model favored.
Sean Burke (Chicago White Sox), the starter LyDia's pitcher score favored, actually outpitched Ronel Blanco: 5.2 IP, 0 ER (0.00 ERA) against 4.0 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 Chicago White Sox bullpen was flagged as elevated risk pregame (Tired). In relief it actually allowed 1 earned run over 3.1 innings (2.70 ERA) — the risk read did not show up on the scoreboard tonight.
The Houston Astros bullpen was flagged as elevated risk pregame (High risk). In relief it actually allowed 5 earned runs over 5.0 innings (9.00 ERA) — the risk read showed up.
Chicago White Sox scored 5, 1.5 fewer than the 6.5 pregame projection.
Houston Astros scored 1, 1.7 fewer than the 2.7 pregame projection.

Pitching plan edge: LyDia gives Sean Burke the edge over the Houston Astros pitching plan (20 points on LyDia's pitcher score). Ronel Blanco is projected for only 4 innings, with the Houston Astros bullpen covering the rest -- this compares Sean Burke's own line against the Houston Astros blended starting-pitcher-and-bullpen quality, not two starters directly.
Blended read: For the Houston Astros, the bullpen is projected to throw more of the game than Ronel Blanco (about 4 innings for the starter), so LyDia grades that side on a whole-game effective ERA of 4.99 rather than Ronel Blanco's own 7.40. Whole-game, that is 3.44 for the Chicago White Sox against 4.99 on the other side, so the blended read leans Chicago White Sox.

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 | 7.8/10, Tired | 8.6/10, High risk |
| Efficiency | 5.9/10, Effective | 4.7/10, Average |
| Combined risk | 7.4/10, Tired | 8.8/10, High risk |
| Relief innings, last 7 days | 30.7 | 29.7 |
| Back-to-back arms | 4 | 5 |
| 7-day ERA | 2.93 | 4.55 |
| 7-day WHIP | 1.21 | 1.35 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
