How the analysis held up
Toronto Blue Jays won. LyDia's model favored the other side.
LyDia's two internal reads disagreed pregame by 51.7 points — the team-strength model favored Seattle Mariners, the run-projection model favored Toronto Blue Jays. The run-projection model had the winner here.
Logan Gilbert (Seattle Mariners) was LyDia's favored starter by pitcher score, but Max Scherzer actually pitched better tonight: 7.0 IP, 0 ER (0.00 ERA) against 5.0 IP, 3 ER (5.40 ERA). The edge did not show up in this game.
The Seattle Mariners bullpen was not flagged pregame, but it had a night worth noting: 4 earned runs allowed over 3.0 relief innings (12.00 ERA) — quietly worse than the pregame read implied.
The Toronto Blue Jays bullpen was flagged as elevated risk pregame (Tired). In relief it actually allowed 0 earned runs over 2.0 innings (0.00 ERA) — the risk read did not show up on the scoreboard tonight.
Seattle Mariners scored 0, 3.6 fewer than the 3.6 pregame projection.
Toronto Blue Jays scored 7, 3 more than the 4 pregame projection.
Likely driver: the Seattle Mariners bullpen allowed 4 earned runs over 3.0 relief innings (12.00 ERA), which was not flagged pregame but showed up anyway, and the opposing starter (0.00 ERA) was sharp when the read expected an edge the other way.

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 | Mariners | Blue Jays |
|---|---|---|
| Fatigue | 5.6/10, Normal | 7.3/10, Tired |
| Efficiency | 2.5/10, Struggling | 4.2/10, Below average |
| Combined risk | 6.9/10, Tired | 7.7/10, Tired |
| Relief innings, last 7 days | 21.7 | 26.0 |
| Back-to-back arms | 5 | 6 |
| 7-day ERA | 7.48 | 4.50 |
| 7-day WHIP | 1.66 | 1.69 |
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 2.5 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.
