THE PICTURE — what's driving the 6-point gapsized against each other · measured against the line — a stat the market already prices can point opposite its usual read
97°F — heat carries the ball51%
The home starter has thrown 488 pitches over 30 daysagainst the over17%
The away team below league average in extra-base hits, last 30 gamesagainst the over14%
Team strength & form leans over — mostly the away team9%
Umpire's strike zone runs narrower than most — fewer called strikes4%
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 average5%
Market: First-5-innings Over 4.5 at -104 (pinnacle, quoted 5:30 PM CDT) · model expects ~5.4 runs · divergence 6 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.
anchor First-5 Over 4.5 -104 → closed -106 · our way
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).
