Optimization diagnostic / LAD
Tyler Glasnow
Tyler Glasnow's tools (50) and production (49) are aligned. Primary finding: existing slider is present, but its movement shape does not currently cover the desired gloveside-sweep window. Also flagged: Stuff-to-Whiff Gap (Command); Usage Underuse: Knuckle Curve. Most actionable fix: increase knuckle curve usage to at least league-average for that pitch type.

Diagnosis
Fixable gaps
| Signal | Cause | Fix | Confidence |
|---|---|---|---|
| Stuff-to-Whiff Gap (Command)0.50 | 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 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 |
| Usage Underuse: Knuckle Curve0.70 | Knuckle Curve grades as the best pitch (whiff 22.8%, CSW 32.2%) but is only thrown 19.1% of the time | Increase Knuckle Curve usage to at least league-average for that pitch typeUsage rebalancing is the simplest optimization with immediate impact | MEDIUM |
