How the Model Reads Seattle Mariners
Seattle plays in T-Mobile Park (0.91x run factor; cool marine air + deep CF dimensions). The model leans heavily UNDER on Mariners totals. Rotation depth (Castillo, Gilbert, Kirby, Miller) is among the best in MLB: F5 picks consistently surface Mariners home games. Bullpen has been a swing factor.
