I grew up much like your son playing baseball year round all the way up until I was ready for college. I had an opportunity to play college ball and turned it down cause I was burnt out on baseball at the time, something that I regret all the time. So it may not be too bad that he gets a break now to really evaluate how much his heart is in the game. Another thing is, idk about his school but we always had a team manager or two that would be at practice all the time and come to the game and take stats and warm up pitchers. It would be a great way to show the coach that he really is dedicated to the game and willing to put in the work. However, I know at that age my ego would have prevented me from doing something like but it sounds like he has the talent so the coaches will eventually see that.
