The case for Kansas City Royals

Bats are hot: +0.127 OPS
Kansas City Royals 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.

Why it is not official

Below the 72.0% official gate
Win probability is 51.7%. LyDia does not make a game official below 72.0%, 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 3.6/10, under the 8.0/10 required for an official pick.
Not enough market edge
The model and the market are too close for the price to matter.
The verdict LyDia passes. Model and market are too close for a clear official pick.

Pitcher edge: San Francisco Giants by 6 points.

How to read this: highlighted cells mark a gap big enough to matter, not just any difference. K-BB% is strikeouts minus walks per batter faced, one of the most predictive skill stats in pitching. HR/9 is home runs allowed per nine innings. Ground-ball rate is neither good nor bad on its own: high ground-ball pitchers trade strikeouts for double plays and fewer home runs.

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.
