STRIKEOUT PREDICTIONS

Three approaches projected side by side for every probable starter: Calculation Engine (deterministic batter-vs-pitch-type matchup math), KNN, and Gradient Boosting (XGBoost) — built on full Statcast pitch-level data (whiff%, CSW%, pitch-type splits). When today's lineup isn't posted yet, projections fall back to each team's expected lineup, built from its last several completed games, so every pitcher gets a full projection all day long. Updated daily.
