I am an AC on DD'd team. Both my DD and the HC's DD pitch. At the end of our turn at offense I will usually walk out to the circle and fill in the ruts left by the opposing pitchers drag foot. Both of our pitchers like a fairly flat surface in front of the rubber. For the first time ever the plate ump approaches me in the third inning and informs me that I cannot be doing that any more or he is going to start considering it a plate visit. Our catchers not even out of the dug out and in most cases I am leaving when the pitcher arrives in the circle for her warm up pitches. I am not doubting the rule but wanted to get clarification that he was correct in informing me of that. This was following ASA rules.
