The Importance of Age in Tennis

The USDA is trying to cut down on the number of kids competing in tennis tournaments. But it's tricky because skill level should be more of an indicator of what ball to use, not age. Some nine-year-olds are fully grown and can crush 17-year-old boys like they did 11 years ago. The best 10 year olds aren't necessarily going to be the best 18 and under kids.
