Cristian Javier
Cristian Javier's tools (66) outpace production (62) by 4 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 Shape: Gloveside Sweep; Arsenal Gap: Gloveside Drop. Most actionable fix: reshape existing changeup to add arsenal shape: armside drop rather than developing a new pitch from scratch.

| 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 Shape: Gloveside Sweep0.70 | Existing Sweeper is present, but its movement shape does not currently cover the desired gloveside-sweep window. | Reshape existing Sweeper 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: 4-Seam Fastball0.60 | 4-Seam Fastball grades as the weakest pitch (whiff 24.7%, CSW 22.8%) but is thrown 51.8% of the time | Reduce 4-Seam Fastball usage in favor of higher-performing offeringsUsage rebalancing is the simplest optimization with immediate impact | MEDIUM |
