What is normal speed for my age?

Ok, i just wanna know this. what is normal speed for a 15 year-old kid (righthanded) cause i throw 78-85 mph is this normal. and if i keep hrowing lik this will it wess up my arm?

i would say anything over 80 is great! And throwing like that wont hurt you unless your throwing with all arm

It depends are you forcing your throws?

no im not forcing it. i just throw it easily. no pain nothing. i can throw bout 300 pitches then my arm kinda starts to hurt. i got good stamina. my schedule its i throw from, 2:00pm-7:00pm then i have supper. every second day so i dont exert myself
