I'm not sure what the exact average is but I'm 13 and my fastball is consistently clocked from 81 to 84mph. What I mostly saw when batting this season was low to mid 70s. It depends on the size and development of the player though. Like I am 6'2" 220 lbs and usually the biggest on the field but the average size player probably hits mid 70s but it is about good location. If you can throw hard and have good command of all your pitches that is more effective than somebody that throws mid 80s with no control.
