Perhaps I need to clarify myself a bit on my position. I truly believe we are pretty much getting at the same thing. I never did clarify equency of pitch type my son throws. Reading back over some of my posts it may come across as if my son throws a lot of breaking balls, perhaps more than his fastball. I generally keep track of pitch type %. Son generally is in the 60-70% fastball range. There have been a few games where he was below 60% and a few above 70%. This thus means his primary pitch(most frequent) is the fastball. For his age, his breaking pitch is well above average as we were told at a recent camp. He was evaluated by a current professional pitcher. Son prides himself in his ability to command that pitch and have success with it. That pride however does not take away from his number one goal- adding velocity to his fastball. He knows he has to bump his velocity up another 3-5 mph by next year if he wants to get in with a good high level program. I know for a fact that he works harder than anyone on the teams he plays with to add that velocity- has always had that fastball velocity focus. Around here he has one of the strongest arms for his age.
Just to be clear, his fastball is and always has been his number one focus. Like many have said- velocity is key to going places. Son knows that and works very hard at it.
