Pitch idea (fragile)

Built from his own fastball (96.3 mph) plus the typical shape 17 pitchers with his slot (39°) throw: a splitter around 88.1 mph, −2.3″ rise, +18.0″ arm-side. On the same model it grades +27 against his changeup, the pitch with the same job (+19 to +31 across the production and three cross-fit models), about 121 on his changeup’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.
