Pitching plan edge: LyDia gives the Houston Astros pitching plan the edge over TBD (29 points on LyDia's pitcher score). Cristian Javier is projected for only 3⅔ innings, with the Houston Astros bullpen covering the rest -- this compares the Houston Astros blended starting-pitcher-and-bullpen quality against TBD's own line, not two starters directly.
Blended read: For the Houston Astros, the bullpen is projected to throw more of the game than Cristian Javier (about 3⅔ innings for the starter), so LyDia grades that side on a whole-game effective ERA of 3.34 rather than Cristian Javier's own 6.59. Whole-game, that is 3.34 for the Houston Astros against 3.58 on the other side, so the blended read leans Houston Astros.
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 | Astros | Padres |
|---|---|---|
| Fatigue | 5.8/10, Normal | 6.6/10, Tired |
| Efficiency | 8.0/10, Dominant | 4.8/10, Average |
| Combined risk | 4.3/10, Normal | 6.7/10, Tired |
| Relief innings, last 7 days | 20.7 | 28.7 |
| Back-to-back arms | 5 | 8 |
| 7-day ERA | 0.87 | 4.71 |
| 7-day WHIP | 0.63 | 1.26 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
