LATEST PG SHOWCASE REPORT
2018 Spring Top Prospect Showcase  
Zachary Bierman is a 2019 LHP with a 6-1 185 lb. frame from Dubuque, IA who attends Western Dubuque HS. Medium athletic build, square shoulders, live body actions. Fast paced delivery with high elbows throughout, has an unusual move onto the rubber before his windup that gets him in rhythm, 3/4's arm slot. Fastball topped out at 85 mph, mostly straight with some angle and occasional cutting action, aggressive with his fastball and throws strikes early in counts. Tends to get out in front of his arm on his curveball, developed a good strike groove with his breaking ball with use but will need to get out front over top of it more consistently. Developing change up. Has a feel for pitching and good athleticism, key in the future is further breaking ball development. Good student, verbal commitment to Illinois State.
