Children form a line in the doubles alley. The first child moves into the court to receive a feed from the clinician. If the child successfully returns the ball, he or she goes to the end of the line. If he or she misses, he or she goes to the opposite alley, the bull pen. The first child in the bull pen line is the first one freed when a child in the hitting line makes a shot. The coach wins if all the children end up in the bull pen. The children win if they can return everyone to the hitting line. Feeds can be varied to make the game challenging.
