How the analysis held up
Cleveland Guardians won, the side LyDia's model favored.
LyDia's two internal reads disagreed pregame by 49.6 points — the team-strength model favored Cleveland Guardians, the run-projection model favored Kansas City Royals. The team-strength model had the winner here.
Parker Messick (Cleveland Guardians), the starter LyDia's pitcher score favored, actually outpitched Seth Lugo: 6.0 IP, 1 ER (1.50 ERA) against 3.2 IP, 9 ER (22.09 ERA). The edge held up.
The Cleveland Guardians bullpen was not flagged pregame, but it had a night worth noting: 0 earned runs allowed over 3.0 relief innings (0.00 ERA) — quietly better than the pregame read implied.
Kansas City Royals scored 1, 3.2 fewer than the 4.2 pregame projection.
Cleveland Guardians scored 11, 7.1 more than the 3.9 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 | Royals | Guardians |
|---|---|---|
| Fatigue | 5.3/10, Normal | 6.5/10, Tired |
| Efficiency | 6.0/10, Effective | 5.1/10, Average |
| Combined risk | 4.8/10, Normal | 6.5/10, Tired |
| Relief innings, last 7 days | 20.3 | 27.0 |
| Back-to-back arms | 4 | 7 |
| 7-day ERA | 3.10 | 4.67 |
| 7-day WHIP | 1.08 | 1.07 |
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 2.8 runs below 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.
