Delay Of Game ...

[BillyMac]

Sometimes it's the simplest things that get me confused.

A1 has designated spot throwin. B1 is aggressively defending the throwin, to the point of reaching over the boundary line. As I'm just about to sound my whistle for a delay warning (no previous warning), A1 releases the ball for the throwin and B1 reaches across the boundary and knocks the passed ball away. Since I was about to charge the delay, I went with a delay warning, and had a do-over.

I know that if B1 hit the ball out of A1's hands, it would be a technical foul. I also know that if B1 hit A1 on the hand before the ball was passed, it would be a intentional foul.

Did I handle this correctly? I know that I should know this, but I'm drawing a blank. I hate it when I question myself on the simplest things, but I would appreciate some closure here. I can't find this specific situation in the casebook. Maybe it's there, but I can't find it.
