Pitch idea (fragile)

Built from his own fastball (94.2 mph) plus the typical shape 20 pitchers with his slot (43°) throw: a changeup around 85.6 mph, 2.3″ rise, +21.1″ arm-side. On the same model it grades +41 against his four-seam, his weakest pitch that breaks the same way (+20 to +45 across the production and three cross-fit models), about 117 on his four-seam’s scale; the comps’ own changeups grade 99 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.
