The USTA has canceled all US Open tennis on Tuesday after the forecast called for worsening conditions in Flushing Meadows.

Rain was lightly drizzling all morning before becoming heavier in Queens just before the scheduled 11 a.m. start.

The USTA was hopeful a dry spell would occur around 2 p.m., but gave up hope shortly before that time came. Those who had tickets for Tuesday can refund them for tickets later in the week or next year. However, a USTA spokesman said tickets are severely limited for the remainder of this tournament.

The Open hadn’t seen a raindrop until Tuesday. It is scheduled to resume Wednesday at 11 a.m., however, rain is in the forecast. If they are able to play it will be an impressive card with Rafael Nadal and Novak Djokovic playing on Arthur Ashe in the afternoon and Serena Williams and Roger Federer playing there at night.

Andy Roddick will start play at 11 a.m. on Louis Armstrong against David Ferrer, while fellow American Donald Young will also start early against No. 4 Andy Murray on the Grandstand. Young will be followed by John Isner, who plays Gilles Simon.

The rescheduling could endanger the Sept. 11 men’s final. The past two years, the men’s final was pushed back to a Monday because of rain.
