BOS 1 · TB 2 — how the graded markets landed
FINAL

Boston Red Sox @ Tampa Bay Rays

Sat 9/19 · 3:10 PM CDT · forecast weather in the grade · ump: confirmed
FIRST 5 INNINGS
no lean
model 51% over · market 52%
TOTAL
no lean
model 51% under · market 52%
the letter is how far we sit from the market, not how sure we are
THE PICTURE — what's driving the 2-point gapsized against each other · measured against the line — a stat the market already prices can point opposite its usual read
Offense profile leans over — mostly the home team40%
Day gameagainst the over21%
Team strength & form leans over — mostly the away team19%
Umpire's strike zone has run wider than the league this past year — more called strikesagainst the over15%
The away starter strikes out 16.6% of batters, adjusted — a lower strikeout rate than average5%
Market: First-5-innings Over 4.0 at -118 (pinnacle, quoted 2:00 PM CDT) · the full picture prices it -106 · model expects ~5.0 runs · divergence 2 points — band none.
SITUATIONAL CONDITIONSdetected for this game · not a grade input — anything that carries weight appears in THE PICTURE
Day game after a night game
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).
