It seems that Randy Choate is keeping the stereotype of lefty bullpen relievers alive. Actually I don't think he is alone in this, most baseball players are superstitious, to the point they repeat certain activities before every game.
Clark Spencer has the story.
Hey, if it works for him, or he just thinks it works for him, I'm all for it.
Personally, it doesn't sound all that quirky to me. You should have seen the crap I went through to get ready to play when I was just in Little League.
