2 umpire mechanics question

[shipwreck]

That's off line from what I am asking. I am saying if as PU you call a strike on a batter you don't go for help since you saw something that convinced you it was a strike. So in Little Jimmy's post he said the fielder made a sweeeping tag attempt and the PU called her out and then went for help which was then overturned. If they were not sure shouldn't they have called her safe and then went for help and if they were sure there was a tag then why go to your partner? I just want to get it right. Dave
