Yes another backcourt question

[CoachP]

Did a search thru threads and didn't see this question, at least not 2 pages worth. Nor do I have my rule books here at work.

A1 dribbling ball in backcourt. A2 is straddling 10 second line (both feet on the floor with left foot in FC and right in BC)

A1 passes to A2 who catches it as she stands as noted above.

A2 establishes her right foot as her pivot (in BC) and brings her left foot up and down into the BC then back to the FC.

IIRC, no violation?

(At least until 10 seconds are up....)
