If you love baseball enough to play it in college, here are a few pointers.
1) Do what you're told. You're not at the top of the food chain anymore like you were in high school. You're with grown men and they won't stand for a know-it-all freshman.
2) Play your heart out. Leave nothing behind. Chances are you're playing there for a reason. You probably have scholarship money and if you don't play to your potential, they can give that money to someone who will.
3) Have fun. Yeah the intensity is picked up in college ball but what did you expect? Go out there and play the game you love. Improvement is always an option.
