Cross the lines? You mean the foul lines?
So, you're in A and the coach from the 3rd base dugout wants to discuss something with you, he can't go past the 3rd base foul line to talk? He must walk all around the diamond to get to you in A, while remaining off the playing field, not crossing the 1st base foul line?
Or are you saying that from A you trot across the diamond to engage this coach in a conversation, in the 3rd base coaching box? Sounds like Tee Ball (the program, not the ump) to me.
This makes no sense.
