Overview
Moving a child past the beginner ball, these orange felt balls use lower compression for a controlled bounce and a reduced speed. They are meant for mid-size junior courts and are approved by the USTA for its youth program.
The lower compression and reduced speed give a child more time to prepare and control the ball, and USTA approval for the youth program makes it easy to use in organized play. The ball suits a mid-size court only, and the listing gives no warranty.
Who it's for
Children in the middle of the junior age range, plus coaches running organized youth programs. Players on full-size courts, or younger children still learning the basics, are better served by balls matched to their court.
Pros and cons
- Lower compression for control
- USTA approved for youth program
- Twelve balls per bag
- Only for mid-size junior courts
Performance notes
Lower compression means the ball flattens more easily on impact, so it rebounds with less speed and a lower, more controlled bounce. The description lists a sharply reduced speed against a regular ball, which gives young players more time to reach it. The felt cover is the contact surface.
