Jacob Misiorowski
Jacob Misiorowski's tools (64) outpace production (63) by 1 points. Primary finding: existing slider is present, but its movement shape does not currently cover the desired gloveside-sweep window. Also flagged: Arsenal Shape: Gloveside Drop; Usage Underuse: Curveball. Most actionable fix: increase curveball usage to at least league-average for that pitch type.

Diagnosis
Fixable gaps
| Signal | Cause | Fix | Confidence |
|---|---|---|---|
| Stuff-to-Whiff Gap (Command)0.09 | 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 |
| Arsenal Shape: Gloveside Drop0.60 | Existing Curveball is present, but its movement shape does not currently cover the desired gloveside-drop window. | Reshape existing Curveball 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: Curveball0.70 | Curveball grades as the best pitch (whiff 62.5%, CSW 43.5%) but is only thrown 7.4% of the time | Increase Curveball usage to at least league-average for that pitch typeUsage rebalancing is the simplest optimization with immediate impact | MEDIUM |
| Usage Overuse: Four-Seam Fastball0.60 | Four-Seam Fastball grades as the weakest pitch (whiff 16.5%, CSW 26.8%) but is thrown 66.9% of the time | Reduce Four-Seam Fastball usage in favor of higher-performing offeringsUsage rebalancing is the simplest optimization with immediate impact | MEDIUM |
