"
STRIKE ZONE: The strike zone is that space over any part of
home plate that is between the batter's armpit and the top of the
batter's knees when the natural batting stance is assumed. Any part
of the ball passing through this strike zone is considered a strike. The
umpire is instructed to determine the batter's strike zone according to
the batter's usual stance when swinging at a pitch."
Where does this say anything about "when it crossed her body" ??
The strike zone is
over the plate at a height determinded by the batter's body,
not where it crosses the batter (unless standing right next to the plate).
