The case for Pittsburgh Pirates

Starting pitcher edge: 23 points
LyDia gives Braxton Ashcraft a 23-point edge over Yusei Kikuchi, driven mainly by WHIP (1.09 vs 1.50) and BB/9 (1.9 vs 3.6).

The case for Los Angeles Angels

Late-inning bullpen advantage
Pittsburgh Pirates relievers have a 3.64 ERA over the last 7 days; Los Angeles Angels relievers have a 6.35. Pittsburgh Pirates also have 8 arms pitching on back-to-back days, against 5 for Los Angeles Angels. If this is still close after six innings, that gap favors Los Angeles Angels.

Why it is not official

Own bullpen carries risk: 8.4/10
The Pittsburgh Pirates bullpen comes in high risk. A lead after six innings is less safe than usual.
Cold stretch at the plate
Pittsburgh Pirates is -0.041 wOBA below its own season form.

Why the setup score is what it is

Conviction: 9.01/10
LyDia's win probability for Pittsburgh Pirates (73.0%) is well clear of a coin flip -- this is a real, stated lean, not a guess.
Pitching plan: 30.67/40
Braxton Ashcraft rates 73 on LyDia's pitcher score, judged on its own merits (50-80 is the credited range). That is a strong start on its own, and it earns most or all of the available credit here.
Offense: 35.04/50
Pittsburgh Pirates's recent offensive form clearly outpaces Los Angeles Angels's over the tracked windows.

Why the price is what it is

Team strength: 56.8%
Before any pitcher or bullpen adjustment, LyDia's team-strength model alone makes Pittsburgh Pirates 56.8% to win. Everything below moves the price from this starting point.
Pitcher score gap: 27 points
The pitcher-score gap favors Pittsburgh Pirates by 27 points. This is the biggest single mover of the price -- a large gap moves it a lot, a small gap barely moves it.
Bullpen adjustment: -0.084
The bullpen-fatigue gap between the two pens nudges the price toward Los Angeles Angels. This moves the price less than the starting pitchers do, since a starter covers more of the game than the bullpen.
Net effect: 56.8% -> 73.0%
Team strength alone had Pittsburgh Pirates at 56.8%. After the pitcher and bullpen terms, the price is 73.0% -- the same number shown as Model Lean above.
The verdict Real value, not an official bet. The +9.4% edge on Pittsburgh Pirates is genuine, but own bullpen carries risk: 8.4/10. If you play it, you are taking on risk LyDia's official card will not.

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.
