If you're hitting it that far, maybe you can be the DH on your off days from pitching in the Bigs...
Seriously, though....I'm confused by posts like this. Why ask a bunch of folks who've never seen you play, never played with or against you, never coached you, what your chances of making the Big Leagues are?
Ask your coaches, go to tryouts and showcases, and answer the question for yourself.
Good luck and have fun!
