If A3 "held" the ball, team control was established by A3 establishing player control (holding or dribbling a live ball inbounds). Team control was lost when A1 took the shot, A2 batting it didn't reestablish it. It's a judgment call as to whether A3's grip while throwing is considered holding it. If it came to rest in his hand, you could claim "yes". If he just batted it, you could claim "no".
