Against a good pitcher that can paint the outside corner she doesn't stand a chance. She would hit everything off of the end of the bat.
No. That isn't in jest. Several teams around here, tell their players to do it. I didn't originate it and I can't remember where I picked it up. Perhaps, it was at a college coach's conference 15 years ago. The funny thing is, this person (man or woman?) measures it out, but then moves back even further. It does very little good to hit w/o a batters box, though.
Watch a MLB game. No one toes the line. They are mostly in the middle of the box.
What I prefer is that they do at first is do the slow motion drill and get to the Power L position and make sure that the sweet spot of the bat is pretty much in the middle of the plate,
The typical swing has a radius, an "arc". The typical hit you want to meet the ball in front of the body. So to hit the outside pitch, with the normal "arc", if you are in position to cover the outside part of the plate when the bat is held straight out, are you still in position to hit the outside ball that you are trying to hit when its half a foot in front of the plate?
