The case for Miami Marlins

Starting pitcher edge: 26 points
LyDia gives Janson Junk a 26-point edge over Robert Stock, driven mainly by BB/9 (2.4 vs 4.4) and WHIP (1.28 vs 1.75).

The case for 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 (53.7% to 49.9%). 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 4.7/10, under the 7.2/10 required for an official pick.
Own bullpen carries risk: 8.1/10
The Miami Marlins bullpen comes in tired. A lead after six innings is less safe than usual.
Cold stretch at the plate
Miami Marlins is -0.013 wOBA below its own season form.

Why the setup score is what it is

Conviction: 8.77/10
LyDia's win probability for Miami Marlins (72.5%) is well clear of a coin flip -- this is a real, stated lean, not a guess.
Pitching plan: 17.33/40
Janson Junk rates 63 on LyDia's pitcher score, judged on its own merits (50-80 is the credited range). Average or below by that measure, so it earns little or none of the available credit here -- independent of who the opponent is throwing.
Offense: 21.35/50
Miami Marlins's recent form does not clearly outpace New York Mets's.

Why the price is what it is

Team strength: 49.9%
Before any pitcher or bullpen adjustment, LyDia's team-strength model alone makes Miami Marlins 49.9% to win. Everything below moves the price from this starting point.
Pitcher score gap: 26 points
The pitcher-score gap favors Miami Marlins by 26 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: -0.039
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: 49.9% -> 72.5%
Team strength alone had Miami Marlins at 49.9%. After the pitcher and bullpen terms, the price is 72.5% -- 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.
