The case for Boston Red Sox

Starting pitcher edge: 19 points
LyDia gives Jake Bennett a 19-point edge over Bubba Chandler, driven mainly by BB/9 (1.9 vs 4.8) and WHIP (1.04 vs 1.38).
Bats are hot: +0.037 wOBA
Boston Red Sox 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 Pittsburgh Pirates

The case is thin
The model finds little going Pittsburgh Pirates's way — it trails on the pitching plan, bullpen, and recent form. The main path to a Pittsburgh Pirates win is variance.

Why it is not official

Below the 61.0% official gate
Win probability is 55.9%. LyDia does not make a game official below 61.0%, no matter how good the price is. This is a value spot, not a high-confidence winner.
Setup quality below the bar
Lab Rating is 6.1/10, under the 8.0/10 required for an official pick.

Why the setup score is what it is

Conviction: 9.49/35
LyDia leans toward Boston Red Sox, but not strongly enough to earn full conviction credit.
Bullpen: 8.45/20
Both bullpens are rated normal — this is close to a wash, not an advantage either way.
The verdict LyDia passes. The combined Lab Rating did not clear the official threshold.

Pitcher edge: LyDia gives Jake Bennett a 19-point edge over Bubba Chandler, driven mainly by BB/9 (1.9 vs 4.8) and WHIP (1.04 vs 1.38).

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.
