Pitch design

Built from his own fastball (92.8 mph) plus the typical shape 17 pitchers with his slot (41°) throw: a sweeper around 81.4 mph, 4.5″ rise, −9.2″ arm-side. On the same model it grades +12 against his slider, the pitch with the same job (+10 to +20 across the production and three cross-fit models), about 111 on his slider’s scale; the comps’ own sweepers grade 105 at the median, so that sits above 88% of them. A season-long project that may not take: about 1.5 runs a season if it does.
