KC 1 · BOS 4 — how the graded markets landed
FINAL

Kansas City Royals @ Boston Red Sox

Sun 9/13 · 2:05 PM CDT · forecast weather in the grade · ump: confirmed
FIRST 5 INNINGS
no lean
model 46% under · market 47%
TOTAL
no lean
model 47% over · market 48%
the letter is how far we sit from the market, not how sure we are
THE PICTURE — what's driving the 4-point gapsized against each other · measured against the line — a stat the market already prices can point opposite its usual read
Day game59%
The home starter strikes out 27.8% of batters, adjusted — a higher strikeout rate than average26%
Offense profile leans over — mostly the away teamagainst the under8%
Team strength & form leans under — mostly the away team4%
Umpire leans overagainst the under1%
WHAT WE COULDN'T SEEpriced into our number — not evidence about this game
No 2025 record of strikes gained behind the plate for the away catcher — graded at league average2%
Market: First-5-innings Under 3.5 at +107 (pinnacle, quoted 1:00 PM CDT) · the full picture prices it +116 · model expects ~4.1 runs · divergence 4 points — band none.
SITUATIONAL CONDITIONSdetected for this game · not a grade input — anything that carries weight appears in THE PICTURE
Catcher rest spotGetaway day (day game, then travel)Low-scoring umpire
Honest row: grades cap at the band — extreme disagreement is as often our error as the market's. Moneyline gets no grade because our model hasn't beaten that market and says so. Graded against the line at grade time; the model was validated against closing lines. Weather from forecast; regrade if conditions flip. F5 grades ride a shorter history (2023-2025).
