The case for Tampa Bay Rays
Why it is not official
Read the full model output

Lab Rating 7.6/10: model edge 31.24, pitcher 16.25, bullpen 8.16, market 15, base 5. Tampa Bay Rays's pen efficiency: Effective (7.1/10). It stayed a value watch because model win probability is 57.1%, below the 72.0% official-pick gate; and Lab Rating is 7.6/10, below the 8.0/10 official-pick gate. Lineup check: Tampa Bay Rays is near its season form (+0.006 OPS); Toronto Blue Jays is a touch below its season form (-0.028 OPS).

Pitcher edge: Tampa Bay Rays by 13 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. Rays and Blue Jays 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 | Rays | Blue Jays |
|---|---|---|
| Fatigue | 5.2/10, Normal | 5.1/10, Normal |
| Efficiency | 7.1/10, Effective | 6.6/10, Effective |
| Combined risk | 4.2/10, Normal | 4.3/10, Normal |
| Relief innings, last 3 days | 11.0 | 9.0 |
| Back-to-back arms | 0 | 1 |
| 3-day ERA | 1.64 | 2.00 |
| 3-day WHIP | 0.91 | 1.11 |
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 and market are close. 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.
