Going for help BBox

[tcblue13]

2 Outs
R1 on 3B, R2 of 2B
B6, Slap Hitter, at the plate.
Clearly clearly clearly has front foot out of the BBox when she slaps the ball through the hole. (BU sees it from C position)
PU does not see it
R1 Scores, R2 stays at second as F7 gets the ball to F5 quickly BR reaches
DC calls time PU grants time
DC asks PU to go to partner for help on batter contacting the ball outside the BBox.

Is this a situation where PU can go for help?
If BU tells PU what he saw and you were PU would you change the call to B6 out?
