Purpose: To work on seeing the ball all the way into the hands.
How it works: Players line up about 30 feet from a coach sitting on a bucket. The coach rolls a numbered tennis ball directly to the first player. As the player receives the ball, she calls out its number and transfers into her throwing motion. She then places the ball in a nearby bucket and the coach rolls a ball to the next player. Drill repeats until everyone has had several turns.
Variation: Extend the drill with balls rolled to the right and left side of players.
Requirements: Three or more players, a bucket, a coach, numbered tennis balls and a field
