IMO, if your son has aspirations of playing after High School in college at some level, I would forgo summer ball and train. Not sure what part of the country you are in but typically Fall Ball would provide an opportunity at a much cheaper rate for your son to showcase his ability. I believe honing his craft to become a better player with a specific work out plan would be of greater service to him than playing games in the summer. In the end making the High School team would be fantastic actually playing on the field in those games a greater reward. Good Luck to you and your son.
