Rule clarification - Sept. 7, 2010: Commit Line, Safe Line, tagging runners out between 3rd and home

The commit line is 21 feet from home plate. The safe line is drawn from the 3rd base edge of the plate to the backstop. The runner cannot be tagged between the lines, the ball must go to the plate before the runner crosses the safe line to record the out. This was done so there would never be any contact around home plate. I hope I was able to help.
