RHP Conner Griffin, freshman at Binghamton University, started remote training with us in October of 2022 going into his senior year of high school. He came in at 6’5” and 188 lbs., sitting 88-90 mph with his fastball. Fast forward to this past August 2023 when he came back for a re-assessment, he weighed in at 200 lbs. and his fastball was sitting 90-93 mph (most recently this fall touching 95 mph at Binghamton).
How did he do it?
