BOS 4 · TEX 3 — how the graded markets landed
FINAL

Boston Red Sox @ Texas Rangers

Fri 9/18 · 7:05 PM CDT · forecast weather in the grade · ump: confirmed
FIRST 5 INNINGS
no lean
model 47% under · market 47%
TOTAL
no lean
model 50% over · market 49%
the letter is how far we sit from the market, not how sure we are
THE PICTURE — what's driving the 3-point gapsized against each other · measured against the line — a stat the market already prices can point opposite its usual read
The home starter likely goes only an inning or two — relievers cover most of the game. Priced in, and it went too far — counts toward the under53%
Team strength & form leans over — mostly the away teamagainst the under17%
Retractable roof — reported closed before first pitchagainst the under12%
The home team's catcher loses strikes on close pitchesagainst the under11%
Umpire's strike zone has run wider than the league this past year — more called strikes6%
Market: First-5-innings Under 4.0 at +105 (pinnacle, quoted 6:00 PM CDT) · the full picture prices it +113 · model expects ~4.4 runs · divergence 3 points — band none.
SITUATIONAL CONDITIONSdetected for this game · not a grade input — anything that carries weight appears in THE PICTURE
Getaway day (day game, then travel)Catcher rest spotHigh-scoring umpireHot 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).
