NEW YORK (AP) The U.S. Tennis Association says the site of the U.S. Open has ``minimal damage'' from Tropical Storm Irene and the Grand Slam tournament will begin on most courts as scheduled at 11 a.m. Monday.

The start of play on the main court, Arthur Ashe Stadium, is being delayed by two hours until 1 p.m.

The gates at the Billie Jean King National Tennis Center will open to the public at 10 a.m.

Irene made landfall in New York as a tropical storm with 65 mph winds, not the 100-mph hurricane that had churned up the East Coast.
