I was calling a game last week and I observed a batter (right handed!) enter the batters box and starting kicking and sweeping dirt onto the front line of the batter box with her foot, trying to cover the line. I noticed she stood in the front of the bx and her foot was close to the line when swinging. Now, I know there is not a rule in USSSA against it, so I didn't say anything, but it bothered me a bit. As the umpire, I guess I could of told her to stop it, but if the coach brought up the fact that there is no rule against it, could I call unsporting behavior as a warning? Anyone have this before?
