The case for Miami Marlins

Starting pitcher edge: 8 points
LyDia gives Sandy Alcantara a 8-point edge over Sean Manaea, driven mainly by expected innings (6.5 vs 5.6) and HR/9 (0.99 vs 1.42).

The case for New York Mets

Late-inning bullpen advantage
Miami Marlins relievers have a 4.55 ERA over the last 7 days; New York Mets relievers have a 4.18. Miami Marlins also have 7 arms pitching on back-to-back days, against 4 for New York Mets. If this is still close after six innings, that gap favors New York Mets.
Team strength favors New York Mets
Before any pitcher or bullpen adjustment, LyDia's own team-strength model has New York Mets ahead (51.0% to 50.1%). The pick still comes from Miami Marlins once the pitcher and bullpen terms are applied.

Why it is not official

Setup quality below the bar
Lab Rating is 5.4/10, under the 7.2/10 required for an official pick.
Own bullpen carries risk: 9.1/10
The Miami Marlins bullpen comes in high risk. A lead after six innings is less safe than usual.
Cold stretch at the plate
Miami Marlins is -0.010 wOBA below its own season form.

Why the setup score is what it is

Conviction: 5.68/10
LyDia's win probability for Miami Marlins (66.4%) is well clear of a coin flip -- this is a real, stated lean, not a guess.
Pitching plan: 25.33/40
Sandy Alcantara rates 66 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: 23.19/50
Miami Marlins's recent form does not clearly outpace New York Mets's.

Why the price is what it is

Team strength: 50.1%
Before any pitcher or bullpen adjustment, LyDia's team-strength model alone makes Miami Marlins 50.1% to win. Everything below moves the price from this starting point.
Pitcher score gap: 11 points
The pitcher-score gap favors Miami Marlins by 11 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: -0.09
The bullpen-fatigue gap between the two pens nudges the price toward New York Mets. This moves the price less than the starting pitchers do, since a starter covers more of the game than the bullpen.
Net effect: 50.1% -> 66.4%
Team strength alone had Miami Marlins at 50.1%. After the pitcher and bullpen terms, the price is 66.4% -- the same number shown as Model Lean above.
The verdict LyDia passes. The combined Lab Rating did not clear the official threshold.

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.
