Pitch idea (fragile)

Built from his own fastball (93.7 mph) plus the typical shape 25 pitchers with his slot (30°) throw: a cutter around 89.6 mph, 9.1″ rise, −4.2″ arm-side. On the same model it grades +8 against his sweeper, his weakest pitch that breaks the same way (+1 to +11 across the production and three cross-fit models), about 106 on his sweeper’s scale; the comps’ own cutters grade 96 at the median, so that sits above 88% of them. The fits disagree, so it isn’t queued.
