KC 2 · HOU 4 — how the graded markets landed
FINAL

Kansas City Royals @ Houston Astros

Wed 9/16 · 7:10 PM CDT · forecast weather in the grade · ump: confirmed
FIRST 5 INNINGS
no lean
model 46% over · market 47%
TOTAL
no lean
model 51% under · market 50%
the letter is how far we sit from the market, not how sure we are
THE PICTURE — what's driving the 1-point gapsized against each other · measured against the line — a stat the market already prices can point opposite its usual read
Umpire's strike zone has run wider than the league this past year — more called strikesagainst the over27%
The home starter has thrown 484 pitches over 30 daysagainst the over19%
Retractable roof — reported closed before first pitch11%
The home team lacks the lefty-righty edge in the lineupagainst the over10%
Team strength & form leans under — mostly the away teamagainst the over1%
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 average32%
Market: First-5-innings Over 4.5 at +106 (pinnacle, quoted 6:00 PM CDT) · the full picture prices it +115 · model expects ~4.8 runs · divergence 1 point — band none.
SITUATIONAL CONDITIONSdetected for this game · not a grade input — anything that carries weight appears in THE PICTURE
none detected for this game
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).
