LATEST PG SHOWCASE REPORT
2021 14U National Showcase  
Boston Kellner is a 2025 RHP/SS, OF with a 6-0 175 lb. frame from Colorado Springs, CO who attends Pine Creek. Lean, athletic build with plenty of projection for the future. Ran the sixty in 7.15 seconds. Primary RHP, he throws from a high 3/4 arm slot and his FB peaked at 85 mph while sitting 78-84 mph. Showed a devastating 12/6 CB that had solid tightness and bite along with having feel for landing it in the zone. Will also manipulate the shape to a 11/5 version as well. In the OF, his best throw was 86 mph and he showed a quick and fluid release. His best throw as an infielder was 85 mph. At the plate he hits out of a balanced stance and uses a leg lift to generate leverage. The bat path has natural loft to it to go along with his solid bat speed and aggressive intent in his swings. Also an excellent student in the classroom.
