Fixable gaps
| Signal | Cause | Fix | Confidence |
|---|---|---|---|
| Arsenal Shape: Gloveside Sweep0.70 | Existing Slider is present, but its movement shape does not currently cover the desired gloveside-sweep window. | Reshape existing Slider to add gloveside sweep rather than developing a new pitch from scratch.Shape refinement would improve platoon coverage while preserving the existing usage signal. | HIGH |
| Arsenal Gap: Gloveside Drop0.60 | No vertical drop pitch (Curveball/Knuckle Curve) — hitters can ignore low zone | Develop a Curveball to cover the gloveside-drop regionFilling this gap would improve platoon coverage and arsenal depth | HIGH |
| Usage Overuse: Sinker0.60 | Sinker grades as the weakest pitch (whiff 12.8%, CSW 24.0%) but is thrown 43.8% of the time | Reduce Sinker usage in favor of higher-performing offeringsUsage rebalancing is the simplest optimization with immediate impact | HIGH |
