How the analysis held up
Cleveland Guardians won, the side Leo's model favored.
Leo's two internal reads disagreed pregame by 19.1 points — the team-strength model favored Cleveland Guardians, the run-projection model favored Baltimore Orioles. The team-strength model had the winner here.
Brandon Young (No clear pitching-plan edge) was Leo's favored starter by pitcher score, but Tanner Bibee actually pitched better tonight: 4.1 IP, 5 ER (10.38 ERA) against 3.2 IP, 6 ER (14.73 ERA). The edge did not show up in this game. Both starters struggled; this was not a case of one clean outing beating one bad one.
The Cleveland Guardians bullpen was flagged as elevated risk pregame (Tired). In relief it actually allowed 0 earned runs over 4.2 innings (0.00 ERA) — the risk read did not show up on the scoreboard tonight.
The Baltimore Orioles bullpen was not flagged pregame, but it had a night worth noting: 0 earned runs allowed over 5.1 relief innings (0.00 ERA) — quietly better than the pregame read implied. Note: 3 of the runs charged to the Baltimore Orioles pitching staff overall were unearned — not something the bullpen's stuff should be blamed for.
Cleveland Guardians scored 9, 5 more than the 4 pregame projection.

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 | Guardians | Orioles |
|---|---|---|
| Fatigue | 7.7/10, Tired | 5.3/10, Normal |
| Efficiency | 6.5/10, Effective | 4.5/10, Average |
| Combined risk | 7.0/10, Tired | 5.6/10, Normal |
| Relief innings, last 7 days | 34.0 | 22.0 |
| Back-to-back arms | 6 | 6 |
| 7-day ERA | 2.38 | 4.91 |
| 7-day WHIP | 1.06 | 1.36 |
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 1.4 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.
