Game Analysis

Omega line prices Giants -173 (36.6% Nats win) but Bayesian posterior fuses to 51.2% Nats win (+14.6% edge, +39 EV on +173 ML); MC sims project 10.7-10.1 score with 73% under 24 (HIGH conf). Extreme $513k whales on Giants contradict Tier 1 models (reduce conf); net injuries favor Giants slightly (-2.3%) but poor data (48% quality, no pitchers) caps conviction. Lean Nats ML + under total.
