Is a fifteen year old throwing a seventy two mph fastball good?

Answer 1

I'll say yes it would be because this is your developing stage and each year you'll go up 2 mph. When you're a senior you'll be at 88 mph, but this will only happen if you work hard and throw strikes.

Answer 2

That is great for a 12 year old. My sister is 14 and when she played Baseball she was throwing at least 65 mph.

Answer 3

Nothing special.
