Pitch idea (fragile)

Built from his own fastball (97.3 mph) plus the typical shape 24 pitchers with his slot (34°) throw: a sweeper around 86.4 mph, 5.2″ rise, −13.1″ arm-side. On the same model it grades +25 against his curveball, the pitch with the same job (+25 to +30 across the production and three cross-fit models), about 123 on his curveball’s scale; the comps’ own sweepers grade 115 at the median, so that sits above 96% of them. That would out-grade 96% of the comps’ real pitches, more likely a result of how the pitch was built than of the pitch, so it isn’t queued.
