Every August the best tennis players in the world descend upon New York for the United States Open. But the city is full of tennis players the rest of the year, too. Young ones.

The photographer Annie Tritt went in search of some of New York’s younger players in August by visiting network sites of National Junior Tennis & Learning, a community-based tennis and education program supported by the U.S.T.A. Foundation with chapters across the country that reach 225,000 youngsters. The organization now known as National Junior Tennis & Learning was founded in 1969 by the tennis stars Arthur Ashe and Charlie Pasarell, as well as the entrepreneur and philanthropist Sheridan Snyder. It has become the largest grass-roots tennis program in the United States.

Morayo Alalade, 7, above, of Queens plays at the Cary Leeds Center for Tennis & Learning in Crotona Park in the Bronx. She has been playing tennis for only a year and lists Serena Williams as her favorite player because, Morayo said, “She always doesn’t stop trying.”

The New York chapters of National Junior Tennis & Learning serve 10,000 children across the five boroughs at varying skill levels. Tritt talked to those she photographed. Their responses have been edited and condensed.
