Today is the day young tennis fans have been waiting for in Queens. 

Arthur Ashe Kids' Day kicked off at the Billie Jean King National Tennis Center in Flushing. 

The annual event was created to honor the legacy of the late tennis great. 

Kids will get to meet some of the pros, practice their moves, and enjoy some live music. 

"It’s fun and it can also be a friendly competition,” one kid said. 

"To see the grounds alive with young people excited about tennis, inspired by role models in their life. Hopefully, Arthur Ashe is one of those people and it is an incredible thing,” said a parent of one of the kids. 

Proceeds from the day help fund free and low-cost tennis programs for kids. 

The festival is part of the U.S. Open's Fan Week -- a series of events leading up to the big tournament. 

The U.S. Open kicks off Monday.
