The case for Kansas City Royals

Bats are hot: +0.011 wOBA
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.

The case for Detroit Tigers

Late-inning bullpen advantage
Kansas City Royals relievers have a 3.86 ERA over the last 7 days; Detroit Tigers relievers have a 4.79. Kansas City Royals also have 5 arms pitching on back-to-back days, against 3 for Detroit Tigers. If this is still close after six innings, that gap favors Detroit Tigers.

Why it is not official

Setup quality below the bar
Lab Rating is 4.7/10, under the 8.0/10 required for an official pick.
Own bullpen carries risk: 8.2/10
The Kansas City Royals bullpen comes in high risk. A lead after six innings is less safe than usual.

Why the setup score is what it is

Conviction: 17.07/20
LyDia's win probability for Kansas City Royals (63.2%) is well clear of a coin flip -- this is a real, stated lean, not a guess.
Pitching plan: 6/20
Michael Wacha rates 6 points better than Drew Anderson on LyDia's pitcher score. A real edge, but well short of the gap that earns full credit here.
Bullpen: 5.07/20
LyDia does not see a meaningful bullpen edge for Kansas City Royals here.
Offense: 19.35/40
Kansas City Royals's recent form does not clearly outpace Detroit Tigers's.

Why the price is what it is

Team strength: 51.7%
Before any pitcher or bullpen adjustment, LyDia's team-strength model alone makes Kansas City Royals 51.7% to win. Everything below moves the price from this starting point.
Pitcher score gap: 6 points
The pitcher-score gap favors Kansas City Royals by 6 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: -0.096
The bullpen-fatigue gap between the two pens nudges the price toward Detroit Tigers. This moves the price less than the starting pitchers do, since a starter covers more of the game than the bullpen.
Net effect: 51.7% -> 63.2%
Team strength alone had Kansas City Royals at 51.7%. After the pitcher and bullpen terms, the price is 63.2% -- the same number shown as Model Lean above.
The verdict LyDia passes. The combined Lab Rating did not clear the official threshold.

Pitcher edge: LyDia gives Michael Wacha a 6-point edge over Drew Anderson, driven mainly by expected innings (6.2 vs 4.0) and BB/9 (2.4 vs 3.4).

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.
