Also flagged: Arsenal Shape: Gloveside Drop; Usage Overuse: Four-Seam Fastball. Most actionable fix: increase changeup usage to at least league-average for that pitch type.

Diagnosis
Fixable gaps
| Signal | Cause | Fix | Confidence |
|---|---|---|---|
| Stuff-to-Whiff Gap (Command)0.10 | Elite stuff tunnels well but pitches land in hittable zones | Reduce heart-of-zone pitches; increase edge and chase attemptsBetter location could push whiff rate toward 24%+ | MEDIUM |
| Arsenal Shape: Gloveside Drop0.60 | Existing Knuckle Curve is present, but its movement shape does not currently cover the desired gloveside-drop window. | Reshape existing Knuckle Curve to add gloveside drop rather than developing a new pitch from scratch.Shape refinement would improve platoon coverage while preserving the existing usage signal. | HIGH |
| Usage Underuse: Changeup0.70 | Changeup grades as the best pitch (whiff 62.4%, CSW 42.6%) but is only thrown 10.7% of the time | Increase Changeup usage to at least league-average for that pitch typeUsage rebalancing is the simplest optimization with immediate impact | HIGH |
| Usage Overuse: Four-Seam Fastball0.60 | Four-Seam Fastball grades as the weakest pitch (whiff 11.7%, CSW 19.1%) but is thrown 34.4% of the time | Reduce Four-Seam Fastball usage in favor of higher-performing offeringsUsage rebalancing is the simplest optimization with immediate impact | HIGH |
