NEW YORK (AP) - U.S. Open organizers plan to try to avoid closing the new roof over Arthur Ashe Stadium as much as possible, even if that means wet courts making for a longer delay.

NEW YORK (AP) U.S. Open organizers plan to try to avoid closing the new roof over Arthur Ashe Stadium as much as possible, even if that means wet courts making for a longer delay.

U.S. Tennis Association executive director Gordon Smith said Monday that a meteorological crew on site should be able to accurately predict rain within about 20-30 minutes. What he doesn't want to see is an overly cautious approach where the roof closes frequently when rain isn't likely.

Smith says: "We want this to be an outdoor tournament; we want to keep the roof open if at all possible. We will run a little risk of getting some rain on the court in order to keep this an outdoor event, to keep the competition fair for everybody."

USTA officials gave an update on construction Monday, with the roof over Ashe and a new Grandstand set to be ready for this year's tournament, which starts Aug. 29.
