A projected 7.58, with a push cushion

OPTIMUS II projected 7.58 total runs. Across 500,000 simulations, Under 8 won outright 55.86% of the time, with exactly eight runs landing another 7.26% and returning the stake. That push protection was the main difference between simply backing a low-scoring script and paying for unnecessary volatility.

Two left-handers, both with caveats

Framber Valdez’s full-season line was not elite, but the recent profile was encouraging — 14 innings, a 1.29 ERA and a 53.6% ground-ball rate over his last two starts. Keeping the ball on the ground is valuable against a Cleveland offense in the lower third of the league. Foster Griffin had a strong season (12–4, 3.31 ERA), but a 4.20 FIP and a rough Cleveland debut — five runs in four innings — meant the read leaned on him returning to baseline, not repeating that volatility.

Neither dominated on paper — and the full-team profiles pointed the same way: contained staff ERAs and respectable bullpens on both sides.

Context: better lineup, minus its centrepiece

Detroit owned the stronger season offense — a 105 wRC+ (7th) to Cleveland’s 94 (23rd) — but the ceiling was cut by the absence of Riley Greene, out injured after leaving Tuesday’s game (.273/.365/.450, 16 HR). With Greene absent and the push sitting at exactly eight, Under 8.0 was the more balanced position than reaching for a lower number.
