I actually study boxing - my dad was a Golden Gloves champion so I learned how to fight at a very young age. Growing up in Brooklyn you always had to watch your back so I pretty much learned to protect myself.
I never smile when I have a bat in my hands. That's when you've got to be serious. When I get out on the field nothing's a joke to me. I don't feel like I should walk around with a smile on my face.
