KC 5 · HOU 2 — how the graded markets landed
FINAL

Kansas City Royals @ Houston Astros

Thu 9/17 · 7:10 PM CDT · forecast weather in the grade · ump: confirmed
FIRST 5 INNINGS · OVER 5.0
C
C cards like this have won 51% over · market 48%
TOTAL · OVER 9.0 RUNS
C
C cards like this have won 52% over · market 48%
the letter is how far we sit from the market, not how sure we are
THE PICTURE — what's driving the 7-point gapsized against each other · measured against the line — a stat the market already prices can point opposite its usual read
The away starter strikes out 17% of batters, adjusted — a lower strikeout rate than average25%
The home team above league average in home runs, last 30 games19%
How closely this umpire's calls have matched the zone this past year, against the league13%
Retractable roof — reported closed before first pitch11%
The away team allowing 4 runs a game, last 30 — below league average. Priced in, and it went too far — counts toward 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 5.0 at +101 (pinnacle, quoted 6:00 PM CDT) · model expects ~5.6 runs · divergence 7 points — band C. lean, not edge-demonstrated C-band cutoffs fitted on OOF 2021-2024; the live record starts with this log. C cards in this market have won 50.9% of 1,034 out-of-sample grades (2021-2024), -0.5 points over break-even at the close. Not a betting-plan cell.

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).
