Optimization diagnostic / LAD
Kyle Hurt
Kyle Hurt's tools (52) outpace production (41) by 11 points. Primary finding: existing changeup is present, but its movement shape does not currently cover the desired arsenal-shape:-armside-drop window. Also flagged: Arsenal Gap: Gloveside Drop; Usage Underuse: Changeup. Most actionable fix: reshape existing changeup to add arsenal shape: armside drop rather than developing a new pitch from scratch.

Fixable gaps
| Signal | Cause | Fix | Confidence |
|---|---|---|---|
| Stuff-to-Whiff Gap (Command)0.27 | 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: Arsenal Shape: Armside Drop0.85 | Existing Changeup is present, but its movement shape does not currently cover the desired arsenal-shape:-armside-drop window. | Reshape existing Changeup to add arsenal shape: armside drop 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 Underuse: Changeup0.70 | Changeup grades as the best pitch (whiff 12.5%, CSW 15.4%) but is only thrown 36.1% of the time | Increase Changeup usage to at least league-average for that pitch typeUsage rebalancing is the simplest optimization with immediate impact | MEDIUM |
