Pitch idea (fragile)

Built from his own fastball (94.8 mph) plus the typical shape 22 pitchers with his slot (32°) throw: a sinker around 94.8 mph, 14.7″ rise, +12.9″ arm-side. On the same model it grades +23 against his changeup, his weakest pitch that breaks the same way (+2 to +40 across the production and three cross-fit models), about 130 on his changeup’s scale; the comps’ own sinkers grade 99 at the median, so that sits above 100% of them. The fits disagree, so it isn’t queued.
