I was sitting at a steel guitar practicing paradiddles and watching the Phillies and the Giants and noticed something odd. Right handed batters wear a batting helmet with an ear flap over the left ear, and left handed batters have a flap over the right ear. Makes perfect sense, until they get on base, wearing the same helmet. Then the runner with the ear flap over his left ear has some added protection, because he could get hit in the left side of the head, which is facing the infield, by a batted ball or a thrown ball if he tries to steal second, third or score a run. The left handed batter’s unprotected ear is hanging right out there, exposed to all manner of injuries while he’s running the bases. They take off their batting gloves and shin protectors and adjust their testicles when they get on base, so why not change helmets, too?
