Venue: Busch Stadium. Park run factor: 0.98. The model adjusts the predicted total by both the flat park run factor (70% weight) and the hand-aware HR factor (30% weight) to capture park-by-batter-handedness effects on home runs.
Active drivers behind this pick: bullpen. Each driver represents a factor pushing the same direction as the model's pick. More aligned drivers = higher confidence.
The pick was made by MarcDuck with the assistance of AI software, not by AI alone. The AI weighs starting pitcher FIP/xFIP, bullpen quality, park factors by handedness, weather, lineup splits, recent form, line movement, and ~25 other factors. MarcDuck reviews the AI's output, refines edge cases (late injury news, narrative-driven line moves, weather updates), and formulates the final pick. Full methodology: /methodology.html.
