Overall Evaluation
JACKSON H MILLER is a versatile high school player with balanced skills in both pitching and hitting. Physically, his sturdy build and strength stand out among peers, providing a solid foundation for his performance. As an outfielder, his exceptional arm velocity (91 mph) and reliable defensive skills allow him to handle routine plays effectively, though improvement in reading complex fly balls would elevate his defensive profile. On the mound, Miller’s fastball showcases high velocity, excellent spin efficiency (97%), and consistent control, making it a dominant pitch. His sinker demonstrates strong horizontal movement, effectively inducing ground balls. Miller’s breaking balls (curveball and slider) offer valuable versatility, with his slider displaying potential as a wipeout pitch. His changeup complements his arsenal, with notable horizontal movement and extension. At the plate, Miller’s hard-hit percentage (50%) and max exit velocity (95.0 mph) indicate strong hitting potential. However, his high ground ball rate (75%) limits his offensive output. Optimizing his swing path to increase launch angle could unlock his full hitting potential, transforming him into a more impactful offensive player. Miller has the tools to become a well-rounded and impactful player.
