How long to wait to make call

[jicecone]

Actually, once that ball is hit out of the infield I can care less about it unless I go out for a catch/no catch. I am hustling into the infield for two reason's: 1. See the touch at first. 2. Be ready for the runner if they advance to other bases. My partner will let me know if it is a catch or no catch and by then I will direct my attention to the location of the ball if I need to.

There is no reason both umpires have to have there eye on the ball at all times, at the same time.
