How Zac Gallen Picks Are Made
Every Zac Gallen pick is made by MarcDuck with the assistance of AI software. The model isolates pitcher quality from team-level signals: park-adjusted FIP/xFIP for the rate stat, last-3-start ERA delta for short-term form, velocity drop penalty for fatigue indicators, home/road and day/night splits for context-specific adjustments, and pitcher H2H history vs the opposing team regressed at 50 TBF for matchup-specific signal. MarcDuck reviews edge cases (recent injury news, bullpen availability, weather updates) and formulates the final pick before publishing.
