The case for Philadelphia Phillies

Starting pitcher edge: 18 points
LyDia gives Zack Wheeler a 18-point edge over Kyle Leahy, driven mainly by K-BB% (24.1% vs 13.4%) and K/9 (10.8 vs 7.9).
Bats are hot: +0.011 wOBA
Philadelphia Phillies 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 St. Louis Cardinals

Late-inning bullpen advantage
Philadelphia Phillies relievers have a 5.74 ERA over the last 7 days; St. Louis Cardinals relievers have a 2.86. If this is still close after six innings, that gap favors St. Louis Cardinals.

Why it is not official

Below the 61.0% official gate
Win probability is 50.2%. 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 4.3/10, under the 8.0/10 required for an official pick.
Own bullpen carries risk: 8.0/10
The Philadelphia Phillies bullpen comes in tired. A lead after six innings is less safe than usual.

Why the setup score is what it is

Conviction: 0/35
LyDia's own win probability for Philadelphia Phillies (50.2%) is close enough to a coin flip that the rating credits no conviction at all — credit only starts above 53%.
Bullpen: 6.98/20
Both bullpens are rated tired — 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 Zack Wheeler a 18-point edge over Kyle Leahy, driven mainly by K-BB% (24.1% vs 13.4%) and K/9 (10.8 vs 7.9).

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.
