missed backcourt

[rsl]

Two man girls JV. I am Trail in the backcourt.

Team B is pressing. I have a 10 second count on A1, who is double teamed and trapped on the table side sideline. A1 jumps and throws a desperation pass to A2, who jumps between two defenders, catches the ball in the air and lands in the backcourt near the sideline opposite table. I didn't see A2 jump- I only see her land, but from her position I can presume she jumped from the front court.

question 1: Do I call the backcourt based on a presumed start to her jump?

My partner saw A2 jump and knows she jumped from frontcourt, but it is my call as trail.

Question 2: If you are the partner, do you make the call for me?

Question 3:As a trail covering a press in two man, how do I cover that much area of the court and see this play?
