AI Summary grounded in real data · zero hallucination
We project the Chicago White Sox as the pick with a 56% win probability, though the edge against the market is not calculated. The selection is primarily supported by 'Last 10 Games Form' and 'Home/Away Split', while the significant disadvantage in 'Starting Pitcher Matchup' remains the primary swing risk. Given that our model does not beat the market over the long term, this prediction should be approached with disciplined caution.
Logistic-regression statistical model — predicts Chicago White Sox vs St. Louis Cardinals by accumulating the log-odds contributions of 12 proven structured metrics. Only structured metrics enter the probability; qualitative and folklore factors get a label only. Predictions are sealed with SHA-256 before the game.
