Pitch idea (fragile)

Built from his own fastball (98.1 mph) plus the typical shape 25 pitchers with his slot (42°) throw: a slider around 89.1 mph, −7.6″ rise, +3.8″ arm-side. On the same model it grades +44 against his four-seam, his weakest pitch that breaks the same way (+27 to +80 across the production and three cross-fit models), about 106 on his four-seam’s scale; the comps’ own sliders grade 107 at the median, so that sits above 32% 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.
