ball is touched last inbounds by player a, player b goes oob while ball is still in the air and attempts to save ball but she has one foot oob. i inadvertently award ball to b team. nobody complains but i know its a bad call, how should i handle and whats the proper mechanic for correcting this?

If you catch it before the ball is inbounded, you can correct it. If you don't catch it before then, it's too late. You gotta live with it.

does it have to be corrected by ap? are can i just say correction team a ball?

No. You just whistle and signal the correct direction. It has nothing to do with the arrow. Give the ball to the correct team.

My mistake. My mistake.

You stepped on the line before you touched the ball. Team A ball.

You're probably going to catch crap but only until you hand the ball in... so hurry up.

Excellent advice right there. Get it going right away and the coach will return to doing his job(coaching) usually and quit his kvetching. If you're standing there, the coach is usually gonna just keep on yapping about it. Tough to yap, too, if you're at the other end of the court.

I had a similar "mistake" situation last Friday (throw-in vs oob). Visiting team inbounding in front court about half-way down the side line. Ball was "tapped" by visiting team into the b/c where they retrieved the ball. I was T and like a dumba**, I called a b/c violation. Turned and started up court and immediately realized what I had done. My partner also realized it right away and she started towards me, I'm sure to tell me about it. I just told both coaches that I had a "brain cramp" and we gave the ball back to visitors.

Can it be corrected before the ball is inbounded or before you hand the ball the thrower in?

The first one might draw a little heat from the coach/crowd because it looks like you are not even sure since you made the ball live, but if you knew it and just handed the ball to a player quickly, blow it immediately.
