Just enjoy the moments that your son gets to play and let him enjoy those moments as well. Baseball becomes as business soon enough, so believe me when I say it is business and nothing personal at that time, so enjoy this time. Every player, whether he throws 77 or 97 has to have a work ethic that is beyond reproach, and that is what you need to be instilling in him right now. It can be frustrating but trying to figure it out instead of having him work through it will put him at a true disadvantage. If he truly loves this game, has a true talent for it and wants to continue to reach the higher levels there are three things he needs to do. Work, work and work.
