My son is a 15 year old sophomore and doing quite well as a pitcher in addition to being a solid power hitter. He has very projectable size and talent and as a result, is being recruited by D1 coaches and pro scouts. Over time he has become dominant using what is now a mid 80's fastball, a decent curveball and a very nasty spit finger fastball that comes in almost the same as his FB then the bottom drops out. He has used this splitter as his "change up" and rarely does anyone hit this pitch. But his HS coaches insist he must also throw a circle change which he hates to throw. As a freshman they required it, while saying NO to the splitter and basically what it amounts to is a "normal" velocity FB at 73-75 MPH and the batters jump all over it. No one can catch up to the FB or Splitter, they ground out or whiff on the curve, but he throws the circle change and it will be hit. The simple question is this: If a former MLB pitcher and 2 pro scouts as well as Tom House who worked with Nolan Ryan say a splitter is a great alternative change up to a circle change and he should use this because he has great control of it, why does he have to waste time with a circle change??? Pro pitching instructors have concluded my son throws the splitter in a healthy manner and he has NEVER had arm pain related to throwing the splitter.
In travel ball in the summer (nationally ranked team) he is allowed to throw what he and the catcher decide and he dominates. In HS he only gives up hits when he throws the change up. How do we go about approaching a HS coach about this. So far as a father I have not said ONE word. I stand back and watch and so far have kept my mouth shut. NEED ADVICE!!
