One pitch Strikeout?

[JefferMC]

I'd just like to see it called. I saw one player (who was preparing to slap) methodically erase the front (i.e. pitcher's end) line of the box on her first at bat in two different games (I say methodically because it took her three tosses with her foot to make sure the line was covered, though she mixed in a couple of non-profitable earth moves, too). PU, standing right behind F2, said nothing. During second game, opposing coach calls time and asks about player obscuring the line... "Didn't see it, Coach." This is the second or third batter in the top of the first inning, with fresh lines...
