Who's call?

[GarthB]

Chris:

What would you have done if he bunted the ball and was tagged by the catcher five feet up the line? You'd have called the out, right?

How about if the pitcher ran him down ten feet up the line? Your call again, right?

So where do we draw the line? At the 45 foot line if you have one, if you don't have one then take the call until you determine the runner is more than half way to first.

As Carl said, cover this in your pre-game.
