The last time I was clocked was in the offseason when I clocked at 82 mph.
My mechanics(at best) looked like this
My team has told me that I throw 'mid to upper 80's' now with these mechanics
My former coach said I was at, in his opinion, 85-86mph and when he saw me pitch, it was the hardest he has ever seen me throw. And he has seen me throw for the last two summers before this one.
I'm trying to get my mechanics to be consistently like this(which has been more accurate for me)
I believe that if I throw with the above mechanics consistently I will be in the upper 80's, at least, consistently.
I made all the links url's to conserve space, so my statement weren't too spread apart.
Let me know if you have any more questions! Thanks for the kind words!
