If you're going to make the call then it has to be done from the outfield. Go out as far as you can but make sure you get stopped to make the call. If make the cut into the infield the catch is now your partner's problem. You need to watch the touch at first and any other play on the runner.

A lot of guys will say they won't go out unless they have to. Their logic being they don't want to run their PU to death. If you're doing your job right you have to come out to view the catch so what's a few more steps to second.
