The youngest child in the tournament is 7 years old, with the oldest child being 12. Despite the major differences in kids' size, the Jones family still sees the good that can come from it.
"I think it's a good experience for them," Sharmila Jones said. "They get to challenge themselves playing against other kids that are older and stronger. Our kids can only just learn from that. I think it's a good thing."
All three of the brothers have been playing for at least four years while Riya has been playing for two years.
While Riya may not have the size and experience of her brothers, she is a part of a new United States Tennis Association program called the 10 and Under Tennis Initiative.
The program is designed to help younger kids that have just started to play tennis further develop with a smaller court progressing from 36 to 60 feet, to the traditional 78-foot court, as well as different sized balls to help their play.
"It changes the court size to adapt to the children's size," said Kathy Hudson, the Junior Tennis Director at the Charleston Tennis Club. "The balls make a huge difference in their progress as well, especially at an early age.
"Each age group (3-5, 6-8, and 8-10) has a different sized ball (red, orange, and green dot). The balls don't bounce as high or move as fast. It allows them to move better and get in position, and be more offensive. There is a lot of interest to learn the game. It's our job to help them stay with it."
Both Eric, 41, and Sharmila, 42, played high school tennis at George Washington and Parkersburg, respectively, but got away from the game during college. That has all but changed with all their children playing, and they couldn't be happier.
"Both of us stopped playing but when they started showing interest in tennis, that's when we started playing again," Sharmila Jones said. "The neat thing is we all six play so much together. We get our exercise and get back into the sport.
"Maybe when they are older and don't feel like they are getting much from us, we will start playing against other people, and maybe even next year in the Public Courts," she added. "That's when we aren't much of a challenge for them anymore, which is getting close."
