How would you handle this?

The pitcher, however, already HAS the new ball, and is hiding it behind the glove. This position is held for a couple of seconds (for the sake of argument, only 3 seconds). The batter, believing the pitcher needs a ball thrown in, takes a step out of the batter's box. A split second before the batter does so, the pitcher had started his delivery. The pitcher, seeing the batter has stepped out, continues the pitch, but rolls it on the ground.

What would you do as the PU?

If we are talking slow pitch I would use rule 6, section 7 Quick Pitch.

The pitcher shall not attempt a quick return of the ball before the batter has taken a position in the batters box or when the batter is off balance.

And since the pitcher cause it.... No Pitch and a warning to the pitcher.
