The tournament, being held at Columbia University, draws some of the most talented players on the continent.
The reigning U.S. National men’s singles champion, 15-year-old Michael Landers, is going up against a crowded field of about 250 players for the title.
The open singles category features world-class athletes volleying with Olympic-level speed and precision.
The tournament also supports a non-profit after-school table-tennis program run by the American Youth Table Tennis Organization.
Organizers say table tennis has seen a resurgence in the city.
"Table tennis is growing in New York City, it's growing around the world," said AYTTO Director Ben Nisbet. "It's a great sport, it's an Olympic sport, it's a high-skill sport, it's a high-energy sport. And at the same time, you can play it in a relatively small and confined area and you don't have to have great weather to play."
The winner will be decided at the championship match on Sunday.
