LATEST PG SHOWCASE REPORT
2021 Midwest Top Prospect Games  
Keller Costello is a 2025 1B/RHP, 3B with a 6-2 230 lb. frame from Ballwin, MO who attends Marquette Senior. Recorded a 8.94 second sixty yard dash time. Big frame and thick build. Primary first baseman, fields the ball deep, uneasy actions at present with limited feel for the position. Will continue to grow into his body and get comfortable at the position. Secondary right-handed pitcher, works exclusively from the stretch with a long and loose arm action that gets offline in the back. Smooth operation overall, arm comes through pretty clean and easy, projects well moving forward. Flashed a curveball with 11-5 shape and vertical drop, solid pitch for his age with some tilt and late bite at times. Threw the curveball often and could land it for strikes. Left-handed hitter with a small lift and replace trigger and a long swing path. Very loose and whippy barrel, showed the ability to elevate the ball. Pull side approach, tended to top spin everything but has power potential as he finds barrel and creates backspin. Great student.
