When does the arrow change?

[ranjo]

9.2.8 SITUATION: Team A is awarded an alternation-possession throw-in. A1lobs the throw-in pass toward A2 who is breaking for the basket. The throw-in pass is too high and lodges between the ring and backboard. RULING: Volation by A1 for lodging the untouched throw-in pass. Team B's ball at the throw-in spot. Since A1 violated during an alternating-possession throw-in, Team A has lost the arrow. Team B will have the arrow for the next alternating-possession throw-in. (6-4-5)

So the question is: When do we change the arrow?

1. As soon as the violation occures.
2. When team B thrower-in is handed the ball.
3. When the ball is legally touched in-bounds.

In most of my games the timer is also keeping the arrow and I want to make sure I can expain it to the table if I get an alternating throw-in violation.
