Another question: I have had more experienced umps tell me not to call "FOUL!" for foul balls. Just raise both hands above your head. But, I call it out because I think it is a disservice to the players, especially runners, if you don't. I've seen runners at first sprint all the way through third before the looked/realized that the ball was already in foul territory. What say you?
DD's coaches tell them to ignore anything they hear from anyone other than the first and third base coaches. I've heard too many parents (and sometimes coaches) yell "FOUL" on a fair ball and the kids aren't familiar enough with the umpire's voice to know who's yelling.
