Head - Stage 1 Junior Green Tennis Ball for Age 9-11 (72 Balls per Bag)
The Stage 1 Green Dot tennis ball is a low-compression transitional ball designed for players aged 9 to 11 and advancing adult beginners. It is the final stepping stone in the International Tennis Federation's (ITF) "Play and Stay" program before players transition fully to standard, maximum-pressure yellow balls.
Key Performance Features
25% Slower: It travels roughly three-quarters the speed of a standard adult tennis ball. This minor reduction gives developing players just enough extra time to adjust their footwork and execute advanced tactical shots.
Slightly Lower Bounce: It has approximately 25% less compression than a standard ball. This keeps the bounce lower and more manageable, preventing the ball from jumping out of a junior player's strike zone during high-velocity rallies.
Full-Court Geometry: It is identical in physical size to a standard ball but features a distinct green dot or green logo. This tells players it is under-pressurized and safe for aggressive full-court training.
Who It Is For
Juniors (Ages 9–11): Tailored for older kids who have graduated from Stage 2 Orange balls and are ready to play on a full-sized 78-foot (24-meter) court using full-length junior or transition rackets (25 to 26 inches).
Intermediate Adult Starters: Highly beneficial for recreational adult beginners who can sustain a rally but struggle with the erratic bounce and extreme speed of standard tournament balls.
