Pitch idea (fragile)

Built from his own fastball (96.3 mph) plus the typical shape 19 pitchers with his slot (37°) throw: a splitter around 88.1 mph, −6.5″ rise, +19.8″ arm-side. On the same model it grades +47 against his four-seam, his weakest pitch that breaks the same way (+39 to +67 across the production and three cross-fit models), about 126 on his four-seam’s scale; the comps’ own splitters grade 103 at the median, so that sits above 100% of them. That would out-grade 100% of the comps’ real pitches, more likely a result of how the pitch was built than of the pitch, so it isn’t queued.
