No Outs, No One on base. Batter run bunts ball in fair territory in between the two batters boxes right in front of the plate. The BR's first step from the left side of the plate (right handed batter) with right foot lands on top of the ball, while her left foot is still in the batters box (the right foot never reaches the ground due to it being on top of the ball). What is the call? and please give rule to back it up.
The umpire called her out due to the ball being in fair territory, I agued that she was still in the batter's box when she touched the ball and therefore should be a foul ball. I also stated that the rule states that she is not out of the batters box until she has established her foot on the ground out of the box. The umpire maintained his position and called her out.
