The away team below league average in extra-base hits, last 30 games28%
Bullpen leans under — mostly the home team27%
Defense leans under — mostly the away team17%
The away team allowing 3.9 runs a game, last 30 — below league average. Priced in, and it went too faragainst the under17%
Starting pitchers leans under — mostly the away team12%
Market: Under 9.0 runs at -118 (pinnacle, quoted 5:30 PM CDT) · model expects ~7.8 runs · divergence 9 points — band B. B-band cutoffs fitted on OOF 2021-2024; the live record starts with this log. B cards in this market have won 52.2% of 1,393 out-of-sample grades (2021-2024), +1.2 points over break-even at the close. Plan cell · suggested stake 0.5u of the flat unit — the stake follows the cell, not this card's number.
Frozen B at 8:15 AM CDT · the number held. · both passes leaned this way.

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.
