Final result
Blue Jays 1, Guardians 6
How the analysis held up
Cleveland Guardians won. LyDia's model favored the other side.
LyDia's two internal reads disagreed pregame by 28.5 points — the team-strength model favored Toronto Blue Jays, the run-projection model favored Cleveland Guardians. The run-projection model had the winner here.
Gavin Williams (No clear pitching-plan edge), the starter LyDia's pitcher score favored, actually outpitched Spencer Miles: 7.0 IP, 0 ER (0.00 ERA) against 1.0 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 Toronto Blue Jays bullpen was not flagged pregame, but it had a night worth noting: 6 earned runs allowed over 7.0 relief innings (7.71 ERA) — quietly worse than the pregame read implied.
The Cleveland Guardians bullpen was not flagged pregame, but it had a night worth noting: 0 earned runs allowed over 2.0 relief innings (0.00 ERA) — quietly better than the pregame read implied. Note: 1 of the runs charged to the Cleveland Guardians pitching staff overall was unearned — not something the bullpen's stuff should be blamed for.
Toronto Blue Jays scored 1, 2.8 fewer than the 3.8 pregame projection.
Likely driver: the opposing starter (0.00 ERA) was sharp when the read expected an edge the other way, and the Cleveland Guardians bullpen quietly shut the game down (0.00 ERA over 2.0 innings), unflagged pregame.

Pitching plan edge: LyDia gives the Toronto Blue Jays pitching plan the edge over Gavin Williams (3 points on LyDia's pitcher score). Spencer Miles is projected for only 3 innings, with the Toronto Blue Jays bullpen covering the rest -- this compares the Toronto Blue Jays blended starting-pitcher-and-bullpen quality against Gavin Williams's own line, not two starters directly.
Blended read: For the Toronto Blue Jays, the bullpen is projected to throw more of the game than Spencer Miles (about 3 innings for the starter), so LyDia grades that side on a whole-game effective ERA of 3.48 rather than Spencer Miles's own 2.88. Whole-game, that is 3.36 for the Cleveland Guardians against 3.48 on the other side, so the blended read leans Cleveland Guardians.

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 | Blue Jays | Guardians |
|---|---|---|
| Fatigue | 5.6/10, Normal | 5.5/10, Normal |
| Efficiency | 4.9/10, Average | 4.7/10, Average |
| Combined risk | 5.7/10, Normal | 5.7/10, Normal |
| Relief innings, last 7 days | 25.0 | 23.0 |
| Back-to-back arms | 5 | 5 |
| 7-day ERA | 3.60 | 5.09 |
| 7-day WHIP | 1.60 | 1.17 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
