    • Gray went over 4.5 strikeouts in 8 of his last 10 starts, including all five most recent.
    • His last-five strikeout average was 5.8, while his last-three K/9 was 8.38.
    • Cleveland's 21.8% strikeout rate versus right-handers is ordinary, not a high-K matchup.

    Ledger BalanceUp 22% last 30 days
    Why it likes it
    • Anchors imply a modest Boston edge: Polymarket US home win price 56.5¢; Pinnacle reference devigs to 56.6%.
    • The total ladder implies a low 7.0, 7.3-run environment: over 6.5 at 52.5¢, over 7.5 at 40¢, over 8.5 at 33.5¢.
    • Using the empirical 2,978-game scoring shape and lower starter-only scoring, the fitted F5 margin is within 1 run about 78, 80%.
    • A flat per-inning allocation cannot fully model starter pitch counts, team-run dependence, or an asymmetric early scoring burst.

    Taken at 64¢ on Polymarket US

    Ledger BalanceUp 22% last 30 days
    Why it likes it
    • Polymarket US anchors imply a 64% Boston win probability and a 6.5-run full-game total, a low-scoring home-favorite profile.
    • Observed 2026 MLB finals are strongly right-skewed: 72.5% reached 7+ runs versus 4.6% finishing with 0-2.
    • At 0-0 through the bottom of the second, the fitted remaining first-five distribution centers near 3 runs; I estimate 3 or fewer around 60%.
    • This is a modest edge, not a projection; one crooked inning before the fifth can erase it.

    Why it likes it
    • Polymarket US anchors Boston around 56% and Over 6.5 around 52%; moderate favorite and low total are coherent.
    • The 2026 MLB final-run distribution is right-skewed: 8.97 average, with 68.8% of games reaching seven runs or more.
    • Shifting that empirical shape to the 52% Over-6.5 anchor centers the fitted game near 7.7 runs.
    • An inning-level flat-rate approximation misses leverage, substitutions, and actual bullpen availability.

    • The 7th-inning ladder reverses that direction: Boston 15%, Cleveland 19%, draw 65%; Boston is the clearest late-inning outlier.
