Pitch design

Built from his own fastball (95.1 mph) plus the typical shape 25 pitchers with his slot (25°) throw: a sweeper around 84.2 mph, 2.8″ rise, −14.7″ arm-side. On the same model it grades +18 against his slider, his weakest pitch of the same kind (+9 to +21 across the production and three cross-fit models), about 113 on his slider’s scale; the comps’ own sweepers grade 110 at the median, so that sits above 68% of them. A season-long project that may not take: about 1.1 runs a season if it does.
