Starting pitcher matchup
Full Pitcher Matchup Tool →| Metric | Padres | Diamondbacks |
|---|---|---|
| Pitching plan | Traditional starter | Limited starter |
| Expected innings | 5⅓ | 4 |
| Throws | R | L |
| LyDia pitcher score (higher is better) | 80 | 39 |
| BB/9 (lower is better) | 2.0 | 6.5 |
| HR/9 (lower is better) | 0.5 | 1.7 |
| Ground-ball rate | 36.1% | 38.3% |
Pitcher edge: LyDia gives Casey Mize a 41-point edge over Mitch Bratt, driven mainly by BB/9 (2.0 vs 6.5) and K-BB% (19.4% vs -3.1%).
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.

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 | Padres | Diamondbacks |
|---|---|---|
| Fatigue | 7.8/10, Tired | 5.6/10, Normal |
| Efficiency | 5.9/10, Effective | 5.5/10, Effective |
| Combined risk | 7.4/10, Tired | 5.4/10, Normal |
| Relief innings, last 7 days | 37.3 | 18.7 |
| Back-to-back arms | 7 | 4 |
| 7-day ERA | 3.38 | 3.86 |
| 7-day WHIP | 1.02 | 1.07 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
