We project the Chicago White Sox as the pick with a 58% win probability, though the edge against the market is uncalculated. The primary drivers supporting this pick are 'Starting Pitcher Matchup' and 'Home Advantage', while the main swing risk lies in the negative 'Team ERA'. Although our model does not beat the market over the long term, the starting pitching edge points toward the Chicago White Sox.
