Proper position

[Buster Light]

You are supposed to move up the 3rd base line as you indicated and when the out has been made at second either come back down the line or cut across the field to the 1st base line for your responsibilities there. If the out is not made at second, you have the runner on second if he goes to 3rd so you stay put. In the event of an overthrow at first, chalk it up to one of the shortcomings of the 2 umpire system.
