Can batter touch home plate when swinging at a pitch ball?

Answer 1

well you can do anything you want. first of all both feet have to be in the batters box while making contact with the ball. if your foot is on home plate while making contact with the ball you are out!!

Answer 2

No, but he still must touch home plate. The runners and batter are not "automatically in"when an "out-of-the-park"home run is hit. The runs aren't scored until each crosses home.
