AT&T National's third round delayed by storm damage; will resume at 1 p.m. With roughly 40 trees down all over Congressional Country Club's Blue Course, organizers of the AT&T National golf tournament have closed the event to spectators and volunteers for Saturday's third round, which has been delayed by nearly six hours. The roads around Congressional, in Bethesda, are strewn with trees after the violent overnight storms that ravaged the entire Washington area. PGA Tour officials were working Saturday morning with Congressional's grounds staff to clear the course and make play possible Saturday. Hear Tiger Woods explain how he would play each of Congressional Country Club's 18 holes. "In the interest of safety for our fans and volunteers, the AT&T national is closed to spectators and volunteers for Saturday," tournament officials said in a statement. The tournament will honor all Saturday tickets on Sunday's round. Play will begin at 1 p.m. from both the first and 10th tees in threesomes, with leader Hunter Mahan taking the course at 3:10 p.m. Tiger Woods, five shots back, will now tee off at 2:40 p.m. Officials were still trying to determine whether television coverage on CBS will be affected. Several trees were down at Congressional, both in fairways and in prime spectator areas, with loose limbs causing potentially dangerous situations. The 14th fairway was completely blocked by a fallen tree, and there is debris strewn about the course. Play was originally slated to begin at 7:10 a.m., but no players had even arrived at the course then.
