How to read this: the scorecards above name the starters; every number lives in this table. Highlighted cells mark a gap big enough to matter. K% and BB% are strikeout and walk rate as a share of batters faced -- K-BB% is the two combined into one skill number. HR/9 is home runs allowed per nine innings. Ground-ball and fly-ball rate are neither good nor bad on their own: high ground-ball pitchers trade strikeouts for double plays and fewer home runs, and on this data source the two rates are complementary (they add to 100%), not independent reads.

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 | Angels | Astros |
|---|---|---|
| Fatigue | 5.0/10, Normal | 6.6/10, Tired |
| Efficiency | 6.4/10, Effective | 5.1/10, Average |
| Combined risk | 4.3/10, Normal | 6.6/10, Tired |
| Relief innings, last 7 days | 17.7 | 28.0 |
| Back-to-back arms | 6 | 4 |
| 7-day ERA | 2.55 | 3.86 |
| 7-day WHIP | 1.02 | 1.39 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
