The case for New York Mets

Pitching plan edge: 20 points
Leo gives Zac Thornton the edge over the Philadelphia Phillies pitching plan (20 points on Leo's pitcher score). Tim Mayza is projected for only 1⅔ innings, with the Philadelphia Phillies bullpen covering the rest -- this compares Zac Thornton's own line against the Philadelphia Phillies blended starting-pitcher-and-bullpen quality, not two starters directly.
Bats are hot: +0.024 wOBA
New York Mets is outhitting its own season form over the last 15 days. Recent form is context, not a model input, but it points the same way here.

The case for Philadelphia Phillies

Team strength favors Philadelphia Phillies
Before any pitcher or bullpen adjustment, Leo's own team-strength model has Philadelphia Phillies ahead (53.0% to 43.7%). The pick still comes from New York Mets once the pitcher and bullpen terms are applied.

Why it is not official

Setup quality below the bar
Lab Rating is 6.6/10, under the 7.2/10 required for an official pick.
Own bullpen carries risk: 6.1/10
The New York Mets bullpen comes in normal. A lead after six innings is less safe than usual.

Why the setup score is what it is

Conviction: 7.99/10
Leo's win probability for New York Mets (71.0%) is well clear of a coin flip -- this is a real, stated lean, not a guess.
Pitching plan: 25.33/40
Zac Thornton rates 70 on Leo'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: 33.17/50
New York Mets's recent offensive form clearly outpaces Philadelphia Phillies's over the tracked windows.

Why the price is what it is

Team strength: 43.7%
Before any pitcher or bullpen adjustment, Leo's team-strength model alone makes New York Mets 43.7% to win. Everything below moves the price from this starting point.
Pitcher score gap: 18 points
The pitcher-score gap favors New York Mets by 18 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: -0.012
The bullpen-fatigue gap between the two pens nudges the price toward Philadelphia Phillies. This moves the price less than the starting pitchers do, since a starter covers more of the game than the bullpen.
Net effect: 43.7% -> 71.0%
Team strength alone had New York Mets at 43.7%. After the pitcher and bullpen terms, the price is 71.0% -- the same number shown as Model Lean above.
The verdict Leo passes. This is a bullpen game -- no confirmed traditional starter, so Leo does not publish an official pick here.

Pitching plan edge: Leo gives Zac Thornton the edge over the Philadelphia Phillies pitching plan (20 points on Leo's pitcher score). Tim Mayza is projected for only 1⅔ innings, with the Philadelphia Phillies bullpen covering the rest -- this compares Zac Thornton's own line against the Philadelphia Phillies blended starting-pitcher-and-bullpen quality, not two starters directly.

Blended read: For the Philadelphia Phillies, the bullpen is projected to throw more of the game than Tim Mayza (about 1⅔ innings for the starter), so Leo grades that side on a whole-game effective ERA of 5.12 rather than Tim Mayza's own 3.46. Whole-game, that is 4.48 for the New York Mets against 5.12 on the other side, so the blended read leans New York Mets.
