Opening tip

[pmasonf]

I saw this recently in a girls high school game and I'm not sure if the ref's call was right. The ref throws up the ball for the opening tip and it goes to a player on team A. A player from team B immediately--and I mean immediately--grabs the ball for a held ball. The ref signalled that the player on team A never had posession and replayed the jump ball. I would have thought that even though the player from team A only had posession for a split second that would have been enough and the ball would go to team B on alternate possession.
