Starting pitcher matchup
Full Pitcher Matchup Tool →| Metric | Cardinals | Blue Jays |
|---|---|---|
| Pitching plan | Traditional starter | Traditional starter |
| Expected innings | 5.1 | 6.0 |
| Throws | R | R |
| LyDia pitcher score (higher is better) | 65 | 84 |
| BB/9 (lower is better) | 3.0 | 3.8 |
| HR/9 (lower is better) | 1.1 | 0.6 |
| Ground-ball rate | 52.0% | 50.0% |
| IP per start (higher is better) | 5.1 | 6.0 |
Pitcher edge: LyDia gives Dylan Cease a 19-point edge over Kyle Leahy, driven mainly by K/9 (13.3 vs 7.8) and K-BB% (26.0% vs 12.5%).
How to read this: the scorecards show ERA, WHIP, K/9, and K-BB%. The table adds complementary traits without repeating them. Highlighted cells mark a gap big enough to matter. 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.
Strikeout Projections Full strikeout projections →
Projections are self-calibrated against graded results (100 graded starts). Official K picks require a 0.7+ strikeout edge, a posted price from at least two books, and a confirmed non-opener workload of at least four expected innings.
Same data source as the Pitcher Matchup Tool, where every starter on the slate is compared side by side.

The Map
Full interactive map →Every team on today's slate, on any two axes you pick. Cardinals 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 | Cardinals | Blue Jays |
|---|---|---|
| Fatigue | 10.0/10, High risk | 6.8/10, Tired |
| Efficiency | 3.1/10, Below average | 2.2/10, Struggling |
| Combined risk | 10.0/10, High risk | 8.2/10, High risk |
| Relief innings, last 3 days | 17.7 | 10.3 |
| Back-to-back arms | 5 | 3 |
| 3-day ERA | 6.11 | 6.97 |
| 3-day WHIP | 1.81 | 2.03 |
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 0.8 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.
