The case for New York Yankees

Late-inning bullpen advantage
Seattle Mariners relievers have a 6.41 ERA over the last 7 days; New York Yankees relievers have a 2.30. If this is still close after six innings, that gap favors New York Yankees.

The case for Seattle Mariners

Starting pitcher edge: Seattle Mariners
LyDia gives Bryce Miller a 18-point edge over Will Warren, driven mainly by WHIP (0.95 vs 1.37) and BB/9 (1.7 vs 2.9).

Why it is not official

Setup quality below the bar
Lab Rating is 4.8/10, under the 8.0/10 required for an official pick.
Pitcher edge points the other way
LyDia gives Bryce Miller a 18-point edge over Will Warren, driven mainly by WHIP (0.95 vs 1.37) and BB/9 (1.7 vs 2.9). That is not the side the model likes here — when the model and the mound disagree, tread carefully.
Cold stretch at the plate
New York Yankees is -0.037 wOBA below its own season form.

Why the setup score is what it is

Pitching plan: 6/20
No meaningful starting-pitcher edge favors New York Yankees in this matchup.
Offense: 4.17/25
New York Yankees's recent form does not clearly outpace Seattle Mariners's.
The verdict LyDia passes. Starting pitcher edge conflicts with the model side.

Pitcher edge: LyDia gives Bryce Miller a 18-point edge over Will Warren, driven mainly by WHIP (0.95 vs 1.37) and BB/9 (1.7 vs 2.9).

How to read this: the scorecards above name the starters; every number lives in this table. Highlighted cells mark a gap big enough to matter. K% and BB% are strikeout and walk rate as a share of batters faced -- K-BB% is the two combined into one skill number. HR/9 is home runs allowed per nine innings. Ground-ball and fly-ball rate are neither good nor bad on their own: high ground-ball pitchers trade strikeouts for double plays and fewer home runs, and on this data source the two rates are complementary (they add to 100%), not independent reads.

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.

Fatigue measures workload. Efficiency measures recent run prevention. Combined risk is what the moneyline and totals systems use.
