I personally called the NCAA and NJCAA an asked if Junior College players can attend my Clutch Performance Baseball clinics. They both said their is no rule stating participation is not allowed. As long as no extra benefits were given. So unsigned JUCO kids can attend Clutch Performance Baseball clinics. Just as long as you pay the same as the high school kids.
Go to
www.clutchperformancebaseball.com and look around. Look at the instructor list an see if there is a school your interested in.
Its free to sign into the database. Take a look and good luck. There is also a summer woodbat league in Nashville called the Sandlott Woodbat League. Many JUCO kids come to that league and find a college from playing all summer with wood. Let me know if you would like more info on the league.
