ATH 1 · TB 10 — how the graded markets landed
FINAL

Athletics @ Tampa Bay Rays

Thu 9/17 · 12:10 PM CDT · forecast weather in the grade · ump: confirmed
FIRST 5 INNINGS
no lean
model 54% under · market 53%
TOTAL
no lean
model 49% under · market 48%
the letter is how far we sit from the market, not how sure we are
THE PICTURE — what's driving the 2-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 strikes30%
Offense profile leans over — mostly the home teamagainst the under24%
Day game18%
The away team playing like a .377 club right now16%
Starting pitchers leans under — mostly the home team12%
Market: First-5-innings Under 4.5 at -123 (pinnacle, quoted 11:00 AM CDT) · the full picture prices it -116 · model expects ~4.9 runs · divergence 2 points — band none.
SITUATIONAL CONDITIONSdetected for this game · not a grade input — anything that carries weight appears in THE PICTURE
Day game after a night gameGetaway day (day game, then travel)Time-zone spot (playing 2+ zones from home)High-strikeout 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).
