Obviously it's best if you can get closer than that, but not everyone can get there depending on what level of ball you are working and the quality of your partner.

Either way, anywhere in that vicinity is a heck of lot better than where the base umpire is, and as someone that has had partners fail to recognize this situation as it is occurring and leaving the play at 2nd completely uncovered, really getting to anywhere and at least acting like you know what's going on is acceptable at most levels.

And really, the pitching rubber is a decent "holding zone" position in this instance. Remember, we have not yet determined that the BR is in fact going to attempt to get to 2nd, so really not a lot of reason to move all the way into the primary position at 2B if there is unlikely to be a play there. You can then adjust your distance accordingly depending on what the runner does.
