DET 6 · TOR 5 — how the graded markets landed
FINAL

Detroit Tigers @ Toronto Blue Jays

Mon 9/14 · 6:07 PM CDT · forecast weather in the grade · ump: confirmed
FIRST 5 INNINGS
no lean
model 55% under · market 53%
TOTAL
no lean
model 52% under · market 51%
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
The away starter mixed his pitches differently than usual last start31%
Retractable roof — reported open before first pitchagainst the under25%
Both catchers gain extra strikes behind the plate17%
Umpire's strike zone has run wider than the league this past year — more called strikes14%
The away team below league average in home runs, last 30 games13%
Market: First-5-innings Under 4.0 at -122 (pinnacle, quoted 5:00 PM CDT) · the full picture prices it -121 · model expects ~4.3 runs · divergence 1 point — band none.
Frozen C at 8:15 AM CDT · the market came toward our number · final grade no lean.
SITUATIONAL CONDITIONSdetected for this game · not a grade input — anything that carries weight appears in THE PICTURE
Heavily used bullpenSeptember call-up lineup
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).
