Shota Imanaga CHC
Shota Imanaga shows a -6-point gap between tools (55) and production (61), but no specific root cause was isolated with sufficient confidence.
Swing path and decision map
Heliot Ramos's tools (84) outpace production (79) by 5 points. Primary finding: excellent plate discipline but too passive on hittable pitches — letting strikes go by.
Dustin May
MIL · Stuff-to-Whiff Gap (Command)
Dustin May's tools grade (44) outpaces production (18) by 26 points. Primary diagnosis: elite stuff tunnels well but pitches land in hittable zones. Secondary signals: Arsenal Shape: Gloveside Drop; Usage Underuse: Curveball. High-fixability path: increase curveball usage to at least league-average for that pitch type.
Mason Fluharty
TOR · Arsenal Shape: Armside Drop
Mason Fluharty's tools grade (53) outpaces production (28) by 25 points. Primary diagnosis: existing changeup is present, but its movement shape does not currently cover the desired armside-drop window.. Secondary signals: Arsenal Gap: Gloveside Drop. High-fixability path: reshape existing changeup to add armside drop rather than developing a new pitch from scratch..
Mason Barnett
ATH · Stuff-to-Whiff Gap (Command)
Mason Barnett's tools grade (51) outpaces production (32) by 19 points. Primary diagnosis: changeup grades as the best pitch (whiff 50.0%, csw 16.7%) but is only thrown 14.5% of the time. Secondary signals: Arsenal Shape: Gloveside Drop; Usage Overuse: 4-Seam Fastball. High-fixability path: increase changeup usage to at least league-average for that pitch type.
Cristian Javier
HOU · Arsenal Shape: Armside Drop
Cristian Javier's tools grade (66) outpaces production (62) by 4 points. Primary diagnosis: existing changeup is present, but its movement shape does not currently cover the desired armside-drop window.. Secondary signals: Arsenal Shape: Gloveside Sweep; Arsenal Gap: Gloveside Drop. High-fixability path: reshape existing changeup to add armside drop rather than developing a new pitch from scratch..
Garrett Mitchell
MIL · Launch Angle Too Low
Garrett Mitchell's tools (87) outpace production (62) by 26 points. Primary finding: groundball-heavy approach with the raw power to drive the ball — leaving fly-ball damage on the table. Also flagged: Contact-Discipline Mismatch. Most actionable fix: elevate bat path to increase average launch angle toward 12-18° range.
Wilyer Abreu
BOS · Power Efficiency Gap
Wilyer Abreu's tools (73) outpace production (68) by 5 points. Primary finding: groundball-heavy approach with the raw power to drive the ball — leaving fly-ball damage on the table. Also flagged: Power Efficiency Gap; Contact-Discipline Mismatch. Most actionable fix: elevate bat path to increase average launch angle toward 12-18° range.
Coby Mayo
BAL · Launch Angle Too High
Coby Mayo's tools (98) outpace production (78) by 20 points. Primary finding: excessive fly-ball angle — producing popups instead of line drives.
Brandon Nimmo
TEX · Launch Angle Too Low
Brandon Nimmo's tools (73) outpace production (68) by 5 points. Primary finding: groundball-heavy approach with the raw power to drive the ball — leaving fly-ball damage on the table. Also flagged: Chase Rate Problem; Contact-Discipline Mismatch. Most actionable fix: elevate bat path to increase average launch angle toward 12-18° range.
