Average HS player or average recruited player? Big difference. I'm in a cold state so the numbers will be lower than those in baseball states, but for varsity players I would say
Avg HS Fastball: 77-80mph
Avg Exit Velo: Low 80s
IF Velo: High 70s
OF Velo: Mid 70s
The numbers for recruited players are going to be much better. I would assume these numbers are dramatically lower for freshman, especially considering the growth at 15/16
