Understanding the Slow Pitch Softball Strike Zone

Question
As an umpire how would you call the strike zone on batters who get set in the back of the batter box but then run towards the ball after it has been pitched?

Answer
Hi Jeff,

I'd call the same as any other batter in SP

STRIKE ZONE: That space over any part of home plate, when a batter assumes a natural batting stance adjacent to home plate, between the batter抯,
B. (Slow Pitch) Back shoulder and the front knee.

The SZ doesn't change if the batter is back, up or moving through the box.
