Very Simple Mechanics Question

[bossman72]

Nobody on and you're in A.

A fly ball is hit in your jurisdiction (to the right half of the outfield).

Now the very simple question that for some reason i'm having trouble with:

Where do you go to make the call?

Obviously on trouble balls, you're out.

But on the ones where you can't decide or the ones that are routine, do you stay out there and watch the catch (and the PU covers 2nd if something happens- similar if you went running out)? Or do you pivot and make the call from the infield so you can get a jump on the BR if he goes for 2nd?

Thanks!
