LATEST PG SHOWCASE REPORT
2023 Northeast Top Prospect Games @ Rutgers (Wed-Thur)  
Jameson Bayliss is a 2025 RHP/3B with a 5-11 175 lb. frame from Williamstown, MA who attends Mt Greylock Reg. As a primary RHP, Bayliss worked from a lean projectable build with additional velocity on the way. He displayed a mechanically sound operation and remained balanced over the rubber well, flashing running action to the FB that ultimately topped out at 80 mph. He effectively mixed a bigger shaped 12-6 breaker that had late downward bite up to 2004 rpm. CH successfully killed spin at 1341 rpm. From the IF, he kept a consistent throwing slot and made plays asked of him, touching 82 mph across the diamond. Offensively, the righty started from a slightly open base with a toe tap trigger and high hand set, creating natural lift in the bat path to generate loud barrels with carry to the middle of the field. He created his best impact when he got the barrel out in front and extended. Ran a 7.44 sixty yard dash.
