65-70 mph would be pretty decent. Age plays a factor obviously, but how and when the body matures(some sooner than others) also needs to be accounted for. I believe most importantly, however, is how mechanically sound is the young pitcher. Good pitching mechanics can easily add 5+ mph no a pitchers fastball, quit often more. And mechanics keep the arm "safer" as well.
you half to have accuracy, and be able to throw fast and throw different types like a curv, or fastballs, or stuff like sliders. I agree with that but when you get that you need to show it off in front of your coach.
I'm guessing between 95 & 105 miles per hour
73 mph
90-100 mph
You want the javelin to be going as fast as possible when you release it. If you are running as fast as you can and THEN throw it, it will have significantly higher velocity, and will travel farther.
The equivalent of an 80mph pitch from 47ft at 54ft is 54/47*80 = 91.9 mph.
Simple flick the wii remote as fast as you can.
Between 55 and 75 MPH
It varies from player to player. Some throw in the 70s to the upper 90s.
it depends on how fast you throw it and if you can throw strikes i would say from 4'11 or above but you dont have to be tall to be a good pitcher it just helps
yes
As fast as you can throw them ;)
