Optimization diagnostic / LAA
Ryan Johnson
Ryan Johnson's production (52) outpaces the tools grade (34) by 17 points. Primary finding: existing splitter 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: Splitter. Most actionable fix: reshape existing splitter to add arsenal shape: armside drop rather than developing a new pitch from scratch.

Fixable gaps
| Signal | Cause | Fix | Confidence |
|---|---|---|---|
| Arsenal Shape: Arsenal Shape: Armside Drop0.85 | Existing Splitter is present, but its movement shape does not currently cover the desired arsenal-shape:-armside-drop window. | Reshape existing Splitter 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: Splitter0.70 | Splitter grades as the best pitch (whiff 36.8%, CSW 14.1%) but is only thrown 17.6% of the time | Increase Splitter usage to at least league-average for that pitch typeUsage rebalancing is the simplest optimization with immediate impact | MEDIUM |
| Usage Overuse: Cutter0.60 | Cutter grades as the weakest pitch (whiff 15.7%, CSW 30.4%) but is thrown 46.7% of the time | Reduce Cutter usage in favor of higher-performing offeringsUsage rebalancing is the simplest optimization with immediate impact | MEDIUM |
