Enjoy playing baseball wherever you can find a place to play. Go ahead and dream about playing professionally.
Don't, I repeat don't let down your family by trying to play professional ball. It isn't going to happen. When I was 17 and playing on an Angel's scout team we had a pitcher who was 26 on the team. He threw a lot of junk, had pinpoint control and not much of a fastball, probably less than 80 mph. He was quite effective pitching against the HS, JC and single A players we typically faced. In fact, he and I combined to beat a professional team out of an independent league one time. He had absolutely no chance of ever signing a contract. Neither did I. Neither do you.
Sorry if this hurts but it is the truth.
