The AT&T National golf tournament was closed to spectators and volunteers for Saturday's third round after a storm that left 1.2 million people in the area without power had ravaged the course.
More than 40 trees were down on the Congressional Country Club's Blue Course, delaying the second round of the PGA Tour event until 1 p.m. ET.
The violent storm in the Washington region tore down trees on the roads into the Bethesda, Md., course. It also left debris along key areas of the course, making it dangerous for spectators.
"In the interest of safety for our fans and volunteers, the AT&T national is closed to spectators and volunteers for Saturday," PGA Tour officials said in a statement. "The tournament will honor all Saturday tickets on Sunday's round."
Mark Russell, the PGA Tour's vice president of rules and competition, said not allowing fans to come out was a very drastic decision.
"But it's in their best interests," he told the Washington Post. "It's a dangerous situation."
Hunter Mahan led the tournament after the second round with tournament host Tiger Woods lurking at five strokes back. It was unclear how CBS' national television coverage would be changed.
"Everything that was inside the ropes was thrown outside the ropes," Russell said. "It's going to take a long time to clean this up."
