Pitching plan edge: Leo gives the Cleveland Guardians pitching plan the edge over the Athletics pitching plan (28 points on Leo's pitcher score). Both starters are projected for a short outing, so this compares each side's blended starting-pitcher-and-bullpen quality, not the two starters directly.
Blended read: For the Athletics, the bullpen is projected to throw more of the game than Mason Barnett (about 3 innings for the starter), so Leo grades that side on a whole-game effective ERA of 4.61 rather than Mason Barnett's own 7.16. For the Cleveland Guardians, the bullpen is projected to throw more of the game than Daniel Espino (about 1⅔ innings for the starter), so Leo grades that side on a whole-game effective ERA of 2.90 rather than Daniel Espino's own 4.73. Whole-game, that is 2.90 for the Cleveland Guardians against 4.61 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 | Athletics | Guardians |
|---|---|---|
| Fatigue | 7.8/10, Tired | 7.7/10, Tired |
| Efficiency | 2.7/10, Struggling | 5.2/10, Average |
| Combined risk | 9.0/10, High risk | 7.6/10, Tired |
| Relief innings, last 7 days | 30.7 | 26.0 |
| Back-to-back arms | 4 | 6 |
| 7-day ERA | 6.75 | 4.15 |
| 7-day WHIP | 1.83 | 1.19 |
Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
