If You Pitch, Don't Do This

Not only can you hurt yourself by accidentally tweaking your shoulder or elbow, but you look like a butt. Remember, baseball is a team sport. Don't do things like show frustration or act unprofessional, which takes the focus off of the team and puts it on yourself. Would Mariano Rivera ever do this?

You're better than that! Act professional. Do your job. Pitch your best and let the chips fall where they may. But most importantly, keep it about your team. Acting like Carlos Zambrano in this pic is selfish.
