[Ref in PA]

Since quizzes and questions are abounding today, I will add this one.

A1 is being closely guarded by B1. The ref begins his 5 second count.

At the count of 3, B1 swipes at the ball and knocks it up in the air where:

A) the ball bounces and A1 catches the ball after one bounce;
B) A1 catches the ball out of the air without moving the pivot foot.

The ref continues the 5 second closely guarded count in both cases.

If the ref correct?

This happened in a girls varsity game on Saturday I worked.
