taking out coaches box line

[umpharp]

I agree with W.M. Blue....you could call a strike, but I wouldn't unless the team had been warned.
Also, I agree the boxes are there the entire game. You can still call a batter out if a slap hitter runs out of the box and hits the ball late in the second game of a doubleheader even if there is no evidence that a batters box ever exsisted.
