"You vs Basket" is one of our favourite games for beginning players. By the way, the above video shows short balls practice as well, but the feeds can be so that players only practice the strokes they have learned.

The coach is inside the service court having a basket of balls to feed from.
The player begins the drill at the baseline, opposite side from the coach.
The player, in order to win a point, will have to hit 5 balls in, in a row. If she does that, she gets 15-0. If, at any time, she misses (hits the net, or out), the score will be 0-15.
The game continues with another attempt for the player to hit 5 balls in a row in. The next point the player wins 30, then 40, followed by a... game.
Eventually, the player will either win or lose a game.

This can be continued for a few games, or even a set.

The "You vs Basket" is also good for beginning players who would like to get ready for upcoming tournaments, since this game tests their consistency under pressure.
