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 7-point gapsized against each other · measured against the line — a stat the market already prices can point opposite its usual read
The away team below league average in extra-base hits, last 30 games36%
Team strength & form leans over — mostly the away teamagainst the under23%
Defense leans under — mostly the away team17%
The away starter walks 11.4% of batters, adjusted — a higher walk rate than average. Priced in, and it went too far — counts toward the under15%
Park & environment leans overagainst the under10%
Market: Under 8.5 runs at -114 (pinnacle, quoted 5:30 PM CDT) · model expects ~8.1 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 52.2% of 2,317 out-of-sample grades (2021-2024), +1.0 points over break-even at the close. Not a betting-plan cell.
Frozen B at 8:15 AM CDT · the market came toward our number · final grade C. · the morning pass leaned B; this pass stands down.
anchor Under 8.5 runs -114 → closed -108 · away
SITUATIONAL CONDITIONSdetected for this game · not a grade input — anything that carries weight appears in THE PICTURE
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.
