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
Starting pitchers leans over — mostly the away team33%
The home team has the lefty-righty edge in the lineup22%
The away team playing like a .575 club right now18%
Umpire's strike zone has run wider than the league this past year — more called strikesagainst the over15%
Retractable roof — reported closed before first pitch13%
Market: First-5-innings Over 4.0 at -123 (pinnacle, quoted 6:00 PM CDT) · model expects ~5.1 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 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.
Frozen C at 8:15 AM CDT · the number held.

SITUATIONAL CONDITIONSdetected for this game · not a grade input — anything that carries weight appears in THE PICTURE
Hot day (90°+)
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).
