Pitch idea (fragile)

Built from his own fastball (97.6 mph) plus the typical shape 24 pitchers with his slot (33°) throw: a slider around 88.6 mph, 3.4″ rise, −5.6″ arm-side. On the same model it grades +17 against his knuckle curve, the pitch with the same job (+14 to +26 across the production and three cross-fit models), about 115 on his knuckle curve’s scale; the comps’ own sliders grade 107 at the median, so that sits above 96% 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.
