Backcourt violation

[BBrules]

A1 brings the ball up from his backcourt and about 4 feet from the division line he launches a baseball type throw toward a teammate moving across the baseline toward the basket. The ball bangs off the backboard about a foot from the rim and low, bounces back, makes one bounce in the frontcourt and back into the hands of the kid that threw it, still in the backcourt. Backcourt violation? Since the ball never touched a player in the frontcourt, does 9-9-2 apply?
