Pitcher edge: San Francisco Giants by 6 points.
How to read this: highlighted cells mark a gap big enough to matter, not just any difference. K-BB% is strikeouts minus walks per batter faced, one of the most predictive skill stats in pitching. HR/9 is home runs allowed per nine innings. Ground-ball rate is neither good nor bad on its own: high ground-ball pitchers trade strikeouts for double plays and fewer home runs.

The Map
Full interactive map →Every team on today's slate, on any two axes you pick. Giants and Royals are highlighted.
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 | Giants | Royals |
|---|---|---|
| Fatigue | 6.5/10, Tired | 6.0/10, Normal |
| Efficiency | 6.0/10, Effective | 1.9/10, Struggling |
| Combined risk | 6.0/10, Normal | 7.6/10, Tired |
| Relief innings, last 3 days | 11.3 | 11.7 |
| Back-to-back arms | 1 | 1 |
| 3-day ERA | 3.18 | 8.49 |
| 3-day WHIP | 1.06 | 1.71 |
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 0.6 runs above the market total. This projection is matchup context, not an official total pick unless LyDia explicitly labels it as one.
What could change the prediction
- A listed starting pitcher is scratched or replaced.
- The moneyline moves enough to remove the current model edge.
- A confirmed lineup materially changes the offensive matchup.
- Late bullpen availability differs from the recent workload data.
- Weather or roof conditions change before first pitch.
