jolietboy,
i wish I would have been clearer. Most all of our data is recorded between the ages of 13 and 18. largest area 15 to 18! Just in recent years have we started to work with younger age groups In larger numbers.
So as much as I would like to answer your question, I can't give you anything meaningful for that age. However, if your son is athletic and works hard, he is very likely to reach his goals. But I'm sure you already know that.
The PG Pre season All American list the 1st teams has 100 players of which only 3 are listed under 6ft. The second team has 10 out of 100 below 6ft. Numbers and ratings are essentially the same only difference appears to be size. Projections appear to weigh heavily in the process and not necessarily confined to pitching. 2014 MLB Batting champion is listed at 5'5. Ratings should be based on current ability not future size.
