BOS 2 · TEX 4 — how the graded markets landed
FINAL

Boston Red Sox @ Texas Rangers

Wed 9/16 · 7:05 PM CDT · forecast weather in the grade · ump: confirmed
FIRST 5 INNINGS
no lean
model 52% under · market 51%
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 0-point gapsized against each other · measured against the line — a stat the market already prices can point opposite its usual read
The home starter strikes out 29.7% of batters, adjusted — a higher strikeout rate than average59%
The home team above league average in home runs, last 30 gamesagainst the under16%
The away team playing like a .579 club right nowagainst the under11%
Retractable roof — reported closed before first pitchagainst the under9%
Umpire's strike zone has run wider than the league this past year — more called strikes4%
Market: First-5-innings Under 4.0 at -114 (pinnacle, quoted 6:00 PM CDT) · the full picture prices it -109 · model expects ~4.5 runs · divergence 0 points — band none.
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).
