A couple of years ago, we wrote about the big foam balls from Gamma for little kids learning how to play. This year, we discovered the next level up, Gamma Quick Kids tennis balls, for school-age kids. The balls are a little bigger than regular balls, and lighter, which mean fewer balls over the fence and therefore fewer tears. The idea is that the child learns correct form because the balls (not unlike softball) slows the game down. I have been playing for most of my life and I love warming up with these as well–even when I play with grownups. Rallies with my kids go on much longer and confidence gets built up much more quickly. Because of the contrasting colors, it’s very clear whether you are putting topspin on the ball. I also learned that the USTA is recommending these balls for all tennis players under the age of 9. $17 for a dozen.
