NEW YORK (AP) The U.S. Tennis Association says "enhanced security procedures" in place for Arthur Ashe Kids' Day - where Michelle Obama will speak - will make for a "longer entry process" at the U.S. Open's main stadium.
The USTA will open Arthur Ashe Stadium at 11 a.m. Saturday, an hour earlier than usual, to try to reduce delays for spectators. The tournament grounds will open at 9:30 a.m. for other activities.
The USTA also says Arthur Ashe Kids' Day is sold out. The event's proceeds go to USTA Serves, the group's charitable foundation, and the Nationals Junior Tennis and Learning network, which Ashe helped found.
