Thanks Jason Fingerman for sharing this simple tennis drill idea. You can use it as an appetizer (warm-up) or the main course in your tennis clinic menu.
This is a dead ball feed (coach feeding all balls one at a time, no live balls). Challenge your players to hit a series of three shots in a row of your choosing, for example three forehands, three backhands, three volleys. Jason also added three overheads but that would make it 3-3-3-3 which spoils the fun of having three 3s in the title. :)
