How This Prediction Was Made

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.
