Foot completely on ground outside the box

[dtwsd]

I started watching the Mich/Tenn game in the 5th inning last night and saw the same batter for Tenn (in two separate at bats) make contact with the ball while her foot was on the ground completely outside the batters box. She was the player who wore the batting helmet that had the jaw protectors. She is a left handed batting slap hitter that each time she made contact with the ball her left foot was clearly on the ground directly in front of home plate between the batters boxes. Now I can understand the HP not being able to see this (maybe he was blocked out, besides he is watching the pitch) but what does surprise me is that neither of the 2 BU's called it. Did anyone else see this last night?
