Pitching plan edge: LyDia gives Clay Holmes the edge over the Chicago White Sox pitching plan (12 points on LyDia's pitcher score). Sean Newcomb is projected for only 2 innings, with the Chicago White Sox bullpen covering the rest -- this compares Clay Holmes's own line against the Chicago White Sox blended starting-pitcher-and-bullpen quality, not two starters directly.
Blended read: For the Chicago White Sox, the bullpen is projected to throw more of the game than Sean Newcomb (about 2 innings for the starter), so LyDia grades that side on a whole-game effective ERA of 4.29 rather than Sean Newcomb's own 2.51. Whole-game, that is 3.64 for the Chicago Cubs against 4.29 on the other side, so the blended read leans Chicago Cubs.
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 | White Sox | Cubs |
|---|---|---|
| Fatigue | 10.0/10, High risk | 8.3/10, High risk |
| Efficiency | 4.9/10, Average | 5.8/10, Effective |
| Combined risk | 10.0/10, High risk | 7.9/10, Tired |
| Relief innings, last 7 days | 41.3 | 27.3 |
| Back-to-back arms | 9 | 6 |
| 7-day ERA | 4.35 | 3.29 |
| 7-day WHIP | 1.33 | 1.13 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
