Akron, Ohio, Aug 4, 2012 (AFP) - Furyk reached 11-under 199 and has a one-shot lead over former British Open champion Louis Oosthuizen, who shot a two-under 68 at the Firestone Country Club course.
Keegan Bradley shot a 67 and was four shots behind. He will be in the final group Sunday, as tee times were moved ahead because weather forecasters are predicting thunderstorms Sunday morning.
Tiger Woods broke par for the first time this week, shooting a two-under 68. Woods, a seven-time winner of this event, however has a lot of ground to make up, as he is 11 shots back.
Rory McIlroy shot a 67 and shares fourth place at minus-six with Steve Stricker, who carded his third-straight 68.
Justin Rose and Bo Van Pelt both shot four-under 66. They were joined in sixth place at five-under-par 205 by John Senden, who had a 69.
Last year's winner Adam Scott managed a one-over 71 to finish three rounds at two-over-par 212.
