Pitching plan edge: Leo gives Parker Messick the edge over the Chicago White Sox pitching plan (7 points on Leo's pitcher score). Hagen Smith is projected for only 2 innings, with the Chicago White Sox bullpen covering the rest -- this compares Parker Messick'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 Hagen Smith (about 2 innings for the starter), so Leo grades that side on a whole-game effective ERA of 3.68 rather than Hagen Smith's own 1.29. Whole-game, that is 3.10 for the Cleveland Guardians against 3.68 on the other side, so the blended read leans Cleveland Guardians.

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 | Guardians | White Sox |
|---|---|---|
| Fatigue | 7.5/10, Tired | 9.0/10, High risk |
| Efficiency | 6.3/10, Effective | 5.0/10, Average |
| Combined risk | 6.9/10, Tired | 9.0/10, High risk |
| Relief innings, last 7 days | 17.7 | 24.3 |
| Back-to-back arms | 5 | 3 |
| 7-day ERA | 3.06 | 4.07 |
| 7-day WHIP | 0.91 | 1.36 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
