Game Analysis

Athletics +2.2 carries a +7.5pp Bayesian edge, but sharp money at Pinnacle is hammering the Mariners side (18.2% divergence). Whale activity on Polymarket ($180K volume) backs the Athletics, creating a three-way conflict. Data quality is degraded (68%) with no pitcher data, forcing a conservative approach. The under 10.5 has a slight edge but historical total struggles and low model agreement make it a pass. Only the spread shows enough posterior strength to warrant a small lean despite the sharp contradiction.
