Robert Gasser

Robert Gasser's production (66) outpaces the tools grade (46) by 20 points. Primary finding: changeup grades as the best pitch (whiff 32.4%, csw 31.6%) but is only thrown 16.4% of the time. Also flagged: Arsenal Gap: Gloveside Drop. Most actionable fix: increase changeup usage to at least league-average for that pitch type.
