Reid Detmers
Reid Detmers's production (67) outpaces the tools grade (56) 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 Shape: Gloveside Sweep; Usage Overuse: Four-Seam Fastball. Most actionable fix: reshape existing changeup to add arsenal shape: armside drop rather than developing a new pitch from scratch.
