Let me clarify what I'm asking.
If I'm PU, and I am 100% sure that the batter didn't swing, and now coach wants to appeal, how is granting the appeal ensuring that we are getting the call right? I know I had it right, and maybe my partner is 50/50 the other way on it. So now we're taking the call from somebody who is 100% sure and giving it to somebody who is 50/50 on it.
The numbers may be exaggerated, and perhaps this doesn't happen when working at a very high level as a professional umpire. But with some of the clowns in our association, I get very nervous on a check swing appeal when I know the batter didn't go. Perhaps if I'm working with a veteran I'm not as nervous.
I know I'm not reinventing the wheel here or anything, I guess I'll just never understand why the rule is that you MUST go to your partner.
And, for the record, didn't have a check swing appeal tonight
Game 1 of post secret signals went just fine.
