Is the ball considered to be in A's backcourt when A1 holds the ball straddling the division line and pivots on the foot that is in A's frontcourt?

The ball is not considered to be in A's backcourt when A1 is straddling the division line and pivots on the foot that is in A's frontcourt. The fundamental rule regarding the backcourt and frontcourt is based on where the player is legally positioned and where the ball itself is located.

In this situation, A1's pivot foot is in the frontcourt, which establishes that the player's center of gravity is in that court. Since the player is holding the ball while one foot is in the frontcourt, the ball maintains its status in the frontcourt as well. The action of straddling the division line does not change this fact, as the determination of court positioning primarily relies on where the player is standing.

Understanding this rule helps clarify how court sections are defined during play, emphasizing the importance of both player positioning and ball placement in determining whether the ball is considered in the frontcourt or backcourt.
