lol very true. Curveballs are not supposed to be fast. I pitch for a rec 16-18 year old baseball league and my curveball is not very fast but it moves a lot.
He needs to get his curveball down to the 70-79 MPH range and his slider down to low to mid 80s. a 92 MPH curveball is essentially a cut or 2 seam fastball IMO
