Alley Cats

Great activity for improving control especially if your players are young enough to be using bounce serves.

Two players in alley across net from each other. First player has 10 balls. Second player lays his/her racquet down to extend the service line across the alley. First player bounce feeds ball across net. Second player shags balls after one bounce, keeps score. 1 point for ball over net in front of racquet; 2 points for hitting racquet; three points for ball landing beyond racquet. All balls must land in alley. When balls run out, switch tasks. Whoever earns the most points with their allotted 10 balls wins.

Progressions
Too hard? Have first player toss ball underhand instead.
Too easy? No bounce - underhand feed. Or add a time limit.
