Pitcher edge: Houston Astros by 8 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. Marlins and Astros 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 | Marlins | Astros |
|---|---|---|
| Fatigue | 6.0/10, Normal | 7.0/10, Tired |
| Efficiency | 3.9/10, Below average | 5.6/10, Effective |
| Combined risk | 6.6/10, Tired | 6.7/10, Tired |
| Relief innings, last 3 days | 10.0 | 11.7 |
| Back-to-back arms | 2 | 3 |
| 3-day ERA | 6.30 | 3.09 |
| 3-day WHIP | 1.20 | 1.37 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
