Arthur Ashe Kids' Day

The US Open is always a youngster-friendly affair, and particularly so on Kids' Day. The event, which honors the humanitarian legacy of 1968 US Open champ Arthur Ashe, features live music, interactive games, plenty of tennis instruction and chances for kids to play against each other and against touring pros, and appearances by top tennis stars and pop stars side by side. This year's lineup is scheduled to include music from Flo Rida, Zara Larsson, Forever in Your Mind and others. There will also be interactive and entertaining tennis-related fun, including appearances by Novak Djokovic and Rafael Nadal. Tickets are relatively inexpensive—cheap enough for budding fans to pay for out of their own allowance.
