If you are a pitching coach then please review this 9-year old pitcher who just starting pitching this spring. He is in a semi-competive league and I do not know how fast he is throwing; he does throw a lot of strikes including one inning with 10 pitches (9 S and 1 B); he is a very motivated youngster and wants to throw all the time (I limited him to four times a week).
Thank you for your constructive criticism
