I'm just trying to get some opinions. Do you think it is best for a 9u pitcher to stay down in 10u for 3 years, or move up to 12u and play in 12u for 3 years. She is a well develped 9yr old pitcher however still needs plenty of work. I believe if she would stay down she would dominate that 3rd year in 10, and gain much needed confidence. Plus that change from 10u to 12u is a big adjustment for pitchers. I realize it depends on the kid. Just thought I would try and get some opinions on this subject with others who have struggled with this decision.
