How the analysis held up
Cleveland Guardians won, the side LyDia's model favored.
Parker Messick (Cleveland Guardians) was LyDia's favored starter by pitcher score, but Anthony Kay actually pitched better tonight: 4.0 IP, 0 ER (0.00 ERA) against 6.0 IP, 3 ER (4.50 ERA). The edge did not show up in this game.
The Chicago White Sox bullpen was flagged as elevated risk pregame (High risk). In relief it actually allowed 4 earned runs over 4.0 innings (9.00 ERA) — the risk read showed up. Note: 2 of the runs charged to the Chicago White Sox pitching staff overall were unearned — not something the bullpen's stuff should be blamed for.
The Cleveland Guardians bullpen was flagged as elevated risk pregame (Tired). In relief it actually allowed 0 earned runs over 3.0 innings (0.00 ERA) — the risk read did not show up on the scoreboard tonight.

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 | Guardians |
|---|---|---|
| Fatigue | 10.0/10, High risk | 7.6/10, Tired |
| Efficiency | 5.2/10, Average | 5.5/10, Effective |
| Combined risk | 9.9/10, High risk | 7.4/10, Tired |
| Relief innings, last 7 days | 46.0 | 28.7 |
| Back-to-back arms | 2 | 4 |
| 7-day ERA | 3.91 | 3.77 |
| 7-day WHIP | 1.30 | 1.12 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
