I know nothing about IVYS. Summer before freshman year in high school, his youth coach told us he could play college baseball and would likely start for HS the next year. I got on this site and started doing research. When he actually DID become a starting pitcher the next year, we told son the following:
If you want to do the work to get to college baseball, here's the deal. We will finance showcases, a travel team, some camps, etc. IF you do the work of arranging lessons, put what you learn to work, do the lifting, get to practice, coach contact, etc
After that, I took over as lead researcher while he worked on improving his skills. The key thing though was it put the ball in his court. He got himself up for 6 a.m. lifting, arranged lessons with pitching coaches, etc., went to practices and arranged extra practices with teammates. A lot of that was outside of his comfort zone when he started and that's how we knew he wasn't doing it to please anyone except himself.
