How the analysis held up
Chicago White Sox won. Leo's model favored the other side.
Leo's two internal reads disagreed pregame by 55.5 points — the team-strength model favored Cleveland Guardians, the run-projection model favored Chicago White Sox. The run-projection model had the winner here.
Gavin Williams (Cleveland Guardians), the starter Leo's pitcher score favored, actually outpitched Anthony Kay: 5.0 IP, 2 ER (3.60 ERA) against 0.1 IP, 1 ER (27.00 ERA). The edge held up.
The Chicago White Sox bullpen was not flagged pregame, but it had a night worth noting: 1 earned run allowed over 8.2 relief innings (1.04 ERA) — quietly better than the pregame read implied. Note: 1 of the runs charged to the Chicago White Sox pitching staff overall was unearned — not something the bullpen's stuff should be blamed for.
Likely driver: the Chicago White Sox bullpen quietly shut the game down (1.04 ERA over 8.2 innings), unflagged pregame.

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 | 6.5/10, Tired | 5.4/10, Normal |
| Efficiency | 7.7/10, Dominant | 6.6/10, Effective |
| Combined risk | 5.2/10, Normal | 4.6/10, Normal |
| Relief innings, last 7 days | 17.3 | 4.7 |
| Back-to-back arms | 3 | 5 |
| 7-day ERA | 1.04 | 1.93 |
| 7-day WHIP | 0.75 | 0.86 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
Run total projection
Full Totals Projections →The model projects 1.5 runs above the market total. A research lean still requires a setup rating of at least 7.0/10. Team totals remain research-only until their graded sample is established.
