Time out?

[paulis]

Had this play today: Team A with the ball in their frontcourt. Pass goes into A1 on the low post. He passes the ball out to A2 at the top of the key but the ball sails over his head and into the backcourt. As the ball is rolling towards B's basket (no one has touched the ball since A1 passed it)and is in A's backcourt, A3 requests a time out. A still has team control and no violation had occured yet, so we grant A the time out. Of course B coach goes primal and I am sure it looked really bad but I think we had the right call. Comments?
