There is a unique way to express one's self on a baseball field that makes a player stand out and be unique. It far outshines all the long hair, funky beards and baggy pants that anyone can dream up. Any joker can do those things. Use the bat, the arm, the glove, the speed. Guarantee that will get you noticed more than any of the cosmetics.
