Storm damage to Congressional Country Club has postponed the start of the AT&T National. Players will tee off in threesomes at holes No. 1 and No. 10 starting at 1 p.m. In addition, spectators and volunteers will not be allowed on the course because of the heat and damage to the course. The temperature reached 100 on Friday and is predicted to be just as hot today with the possibility of another severe thunderstorm. The tournament will honor Saturday tickets on Sunday.

Hunter Mahan (135) holds a two-stroke lead on Brendon de Jonge (137), Jimmy Walker (137) and Robert Garrigus (137). Tiger Woods (140) is five back. Mahan tees off at 3:10. Woods at 2:40
