Asking for help from feloow umpire

[sabattis]

I understand what you're saying, however, it is quite possible that your partner wouldn't (maybe even shouldn't) be watching the play in question. Therefore, if so, his response to "do you have a tag" or similar could only be "no" or " i didn't see it", so you remain stuck with what you originally might have called, only to do it later after much else may have happened. I say make the call, wait for a manager to ask you if you want to ask your partner for help. If you're confident, don't ask, explain what you saw. If not, call time and discuss it privately - that way you don't create the awkward situation of forcing your partner to react to something he may have no clue about. If he did see something different, then you can change it.
